Cold-Rolled Steel Coils — Precise Dimensions, Clean Surface

Cold-rolled steel is hot-rolled strip that has been further reduced at ambient temperature, producing a thinner, stronger and dimensionally precise material with a clean, smooth surface. It is the preferred substrate for products that are painted, plated, deep-drawn or machined to tight tolerances. Sino East Steel supplies cold-rolled coils and sheets in thicknesses from 0.15 mm to 3.5 mm, widths from 600 mm to 1,800 mm, in grades DC01 to DC06 (EN 10130), SPCC to SPCE (JIS G3141), and structural grades like S235JR-CR. Material can be delivered as full hard, skin-passed or annealed per your forming requirements, with slit coils and cut-to-length sheets available.

Cold Rolling and Annealing

Hot-rolled pickled coil is cold-reduced on tandem mills to the target gauge, which work-hardens the steel. For forming applications the coil is then annealed in a controlled atmosphere to restore ductility, and skin-passed to achieve the final surface finish and flatness. The result is a product with tight thickness tolerance (±0.02 mm typical), excellent surface quality and consistent mechanical properties across the full coil length.

Applications

Cold-rolled steel is consumed by manufacturers of automotive components, appliances, office furniture, lockers and shelving, electrical enclosures, lighting fittings, drums and containers, and as the base for galvanized, color-coated and tin-plated products. Polish manufacturers of metal furniture and household goods rely on cold-rolled coil for its consistent gauge, which keeps pressing and forming dies running without adjustment.

Choosing the Right Cold-Rolled Grade

For simple bending and general fabrication choose DC01/SPCC. For deep drawing use DC04 or DC06 (SPCD/SPCE) with the appropriate r-value. If the part is load-bearing, select a structural grade such as S235JR-CR or HC340LA for higher yield strength. Always state the surface finish (bright or dull) and the required mechanical values, because these determine how the coil performs in your press.

Product Advantages for Press Shops and Appliance Makers

Cold-rolled steel earns its place in high-volume production because its consistent gauge and surface quality keep dies running without constant adjustment. Our coils offer tight thickness tolerance, controlled surface roughness and batch-to-batch mechanical consistency — the three properties that matter most to Polish press shops and appliance manufacturers. We can supply full hard coil for your own annealing line or annealed skin-passed coil ready for forming, and we support development batches with smaller coil weights before committing to program volumes. Because we are the mill, technical support and grade substitution advice come from the people who made the steel.

Quality Control & Certification

Every batch of material delivered from our Tianjin plant passes through a documented inspection routine: chemical composition analysis, tensile and yield testing, dimensional checks and, where applicable, hydrostatic or flattening tests. Each consignment ships with an EN 10204 3.1 mill test certificate (MTC) and batch traceability records, so your incoming inspection at Gdansk, Gdynia, Szczecin or any other EU port is straightforward. The factory operates under an ISO 9001:2015 quality management system and is independently audited by SGS and TUV Rheinland for production capacity and export reliability.

Inspection & Testing Before Shipment

Before any material leaves the plant it passes through a defined inspection gate. Dimensional checks are performed against the ordered specification, surface quality is inspected visually and with instruments where required, and the relevant mechanical and chemical tests are verified against the mill certificate. For pipe and tube products, hydrostatic and non-destructive testing results are reviewed against the standard’s acceptance criteria. Customers who request it can witness the inspection or receive photographs and video of the loaded goods before the vessel sails — a practical way to build confidence without travelling to China.

Export Documentation Included

Every order is shipped with a complete documentation set: commercial invoice, packing list, bill of lading, certificate of origin, and the EN 10204 3.1 mill test certificate with heat numbers and test results. Where your project requires third-party inspection, we can arrange SGS, TUV or Bureau Veritas inspection before loading, with the inspection report issued in English for easy clearance in the EU.

Why European Buyers Source This Product from Sino East Steel

Importing steel from China to Poland is a routine, well-understood process when you work with a manufacturer that has done it hundreds of times. Sino East Steel combines factory-direct pricing with export experience across the EU, so you avoid the margin stack of trading companies and the documentation delays that slow down first-time imports. Our export team prepares commercial invoices, packing lists, certificates of origin, and the EN 10204 3.1 mill certificates your quality department and customs broker expect. We also coordinate vessel booking from Tianjin/Xingang to Baltic ports, and for regular customers we can hold production slots so repeat orders keep your warehouse stocked without interruption.

Because we are the manufacturer, specification changes, coating requirements, packing instructions and delivery dates are agreed directly with the people who control the production line. This transparency is what distributors and contractors in Poland value most: one accountable partner, one set of documents, and material that matches the sample on every shipment.

Packaging & Delivery to Poland and the EU

Products are packed in seaworthy export condition: steel strapping, waterproof wrapping, and wooden or steel pallets where required, with clear marking for safe handling. For pipe and tube orders we use the standard export bundle format with plastic end caps on request. Sea freight to Polish and Baltic ports (Gdansk, Gdynia, Szczecin, Klaipeda) is arranged from Tianjin or Xingang port, with typical lead times of 15–25 days after production. FCL and LCL options are both available, and mixed-container consolidation is offered for regular customers who combine several product lines in one delivery.

Customization & Value-Added Services

Beyond standard supply, our finishing lines can prepare material for your exact production step: cutting to length, drilling, bevelling, threading, coating, marking and custom bundling per your drawings. Packaging can be adapted to your handling equipment — pallets, frames, slings or individual protective wrapping — and private labeling is available for distributors who resell under their own brand. For customers with regular monthly programs, we schedule production slots so that reorder quantities arrive on time, allowing you to run leaner stock without risking supply gaps on your own production line.

Technical Support & After-Sales Service

Our export engineers support you from specification to installation: confirming grade and size selections, advising on coatings and packing for your climate and handling equipment, and answering technical questions from your quality department. After delivery, we keep the batch records on file and can issue additional documentation, arrange replacement paperwork, or support you in the rare case of a claim. For Polish customers this means a single point of contact who knows your orders, your specifications and your delivery history — service that trading intermediaries rarely match.

Storage & Handling on Site

To protect the material between delivery and installation, store it off the ground on sleepers, keep it dry and allow air circulation between layers. Galvanized products should be separated from black steel to avoid zinc staining, and painted or polished surfaces should keep their protective wrapping until installation. When lifting, use fabric slings or spreader bars for long lengths to avoid damage. Our packing lists indicate bundle weights and lifting points, and our export team can advise on safe unloading at your warehouse or construction site.

How to Order & Request a Quotation

To receive a firm quotation, please send your required specification: grade and standard, dimensions, quantities (in tons or pieces), end use, and the destination port in Poland or the EU. Our export team replies within 24 hours with pricing, availability and a proposed shipping schedule. We work with T/T and L/C payment terms, and for established EU customers longer payment arrangements can be discussed on a project basis.

Frequently Asked Questions

What is the difference between full hard and annealed cold-rolled coil?

Full hard coil is cold-reduced without annealing — it has high strength but is not suitable for forming. Annealed (and skin-passed) coil has restored ductility and is the standard choice for pressing, deep drawing and general fabrication.

Do you supply cold-rolled coil with surface oiling?

Yes, coils can be supplied lightly oiled or dry per your storage and handling preference. Oiled material protects the surface during transit and storage in humid conditions.

What documents do you provide with each shipment?

Each shipment includes the EN 10204 3.1 mill test certificate, packing list, commercial invoice and bill of lading. Inspection reports and third-party certificates (SGS, TUV, Bureau Veritas) can be arranged before loading if your project requires them.

Can you supply to Polish and European standards?

Yes. We regularly export to EN and DIN specifications used across the EU, including EN 10219, EN 39, EN 10210, EN 10305 and DIN 2440, in addition to ASTM and API standards. Tell us the standard your project specifies and we will quote accordingly.

What are your MOQ and lead times?

MOQ depends on the product and size — typically from 1 to 10 tons for standard lines. Production and shipping to Polish ports normally takes 15–25 days from order confirmation.

Do you ship to Polish ports and handle customs paperwork?

Yes. We ship FOB Tianjin/Xingang, CIF or CFR to Gdansk, Gdynia, Szczecin and other Baltic ports, and we prepare the export documentation (commercial invoice, packing list, bill of lading, certificate of origin, mill certificates) needed for import clearance in Poland.

Can we arrange a pre-shipment inspection?

Yes. Third-party inspection by SGS, TUV, Bureau Veritas or your own representative can be arranged before loading, and the inspection report is provided before the vessel departs.

Do you offer samples before a full order?

For most products we can provide small samples or cut pieces so your quality department can verify the material. Sample cost is credited against the first order for regular customers.

Why European Buyers Source This Product from Sino East Steel

Importing steel from China to Poland is a routine, well-understood process when you work with a manufacturer that has done it hundreds of times. Sino East Steel combines factory-direct pricing with export experience across the EU, so you avoid the margin stack of trading companies and the documentation delays that slow down first-time imports. Our export team prepares commercial invoices, packing lists, certificates of origin, and the EN 10204 3.1 mill certificates your quality department and customs broker expect. We also coordinate vessel booking from Tianjin/Xingang to Baltic ports, and for regular customers we can hold production slots so repeat orders keep your warehouse stocked without interruption.

Because we are the manufacturer, specification changes, coating requirements, packing instructions and delivery dates are agreed directly with the people who control the production line. This transparency is what distributors and contractors in Poland value most: one accountable partner, one set of documents, and material that matches the sample on every shipment.

Packaging & Delivery to Poland and the EU

Products are packed in seaworthy export condition: steel strapping, waterproof wrapping, and wooden or steel pallets where required, with clear marking for safe handling. For pipe and tube orders we use the standard export bundle format with plastic end caps on request. Sea freight to Polish and Baltic ports (Gdansk, Gdynia, Szczecin, Klaipeda) is arranged from Tianjin or Xingang port, with typical lead times of 15–25 days after production. FCL and LCL options are both available, and mixed-container consolidation is offered for regular customers who combine several product lines in one delivery.

Customization & Value-Added Services

Beyond standard supply, our finishing lines can prepare material for your exact production step: cutting to length, drilling, bevelling, threading, coating, marking and custom bundling per your drawings. Packaging can be adapted to your handling equipment — pallets, frames, slings or individual protective wrapping — and private labeling is available for distributors who resell under their own brand. For customers with regular monthly programs, we schedule production slots so that reorder quantities arrive on time, allowing you to run leaner stock without risking supply gaps on your own production line.

Technical Support & After-Sales Service

Our export engineers support you from specification to installation: confirming grade and size selections, advising on coatings and packing for your climate and handling equipment, and answering technical questions from your quality department. After delivery, we keep the batch records on file and can issue additional documentation, arrange replacement paperwork, or support you in the rare case of a claim. For Polish customers this means a single point of contact who knows your orders, your specifications and your delivery history — service that trading intermediaries rarely match.

Storage & Handling on Site

To protect the material between delivery and installation, store it off the ground on sleepers, keep it dry and allow air circulation between layers. Galvanized products should be separated from black steel to avoid zinc staining, and painted or polished surfaces should keep their protective wrapping until installation. When lifting, use fabric slings or spreader bars for long lengths to avoid damage. Our packing lists indicate bundle weights and lifting points, and our export team can advise on safe unloading at your warehouse or construction site.

Yes. We regularly export to EN and DIN specifications used across the EU, including EN 10219, EN 39, EN 10210, EN 10305 and DIN 2440, in addition to ASTM and API standards. Tell us the standard your project specifies and we will quote accordingly.

What are your MOQ and lead times?

MOQ depends on the product and size — typically from 1 to 10 tons for standard lines. Production and shipping to Polish ports normally takes 15–25 days from order confirmation.

Do you ship to Polish ports and handle customs paperwork?

Yes. We ship FOB Tianjin/Xingang, CIF or CFR to Gdansk, Gdynia, Szczecin and other Baltic ports, and we prepare the export documentation (commercial invoice, packing list, bill of lading, certificate of origin, mill certificates) needed for import clearance in Poland.

Can we arrange a pre-shipment inspection?

Yes. Third-party inspection by SGS, TUV, Bureau Veritas or your own representative can be arranged before loading, and the inspection report is provided before the vessel departs.

Cold-Rolled Steel Coils — Precise Dimensions, Clean Surface

Cold-rolled steel is hot-rolled strip that has been further reduced at ambient temperature, producing a thinner, stronger and dimensionally precise material with a clean, smooth surface. It is the preferred substrate for products that are painted, plated, deep-drawn or machined to tight tolerances. Sino East Steel supplies cold-rolled coils and sheets in thicknesses from 0.15 mm to 3.5 mm, widths from 600 mm to 1,800 mm, in grades DC01 to DC06 (EN 10130), SPCC to SPCE (JIS G3141), and structural grades like S235JR-CR. Material can be delivered as full hard, skin-passed or annealed per your forming requirements, with slit coils and cut-to-length sheets available.

Cold Rolling and Annealing

Hot-rolled pickled coil is cold-reduced on tandem mills to the target gauge, which work-hardens the steel. For forming applications the coil is then annealed in a controlled atmosphere to restore ductility, and skin-passed to achieve the final surface finish and flatness. The result is a product with tight thickness tolerance (±0.02 mm typical), excellent surface quality and consistent mechanical properties across the full coil length.

Applications

Cold-rolled steel is consumed by manufacturers of automotive components, appliances, office furniture, lockers and shelving, electrical enclosures, lighting fittings, drums and containers, and as the base for galvanized, color-coated and tin-plated products. Polish manufacturers of metal furniture and household goods rely on cold-rolled coil for its consistent gauge, which keeps pressing and forming dies running without adjustment.

Choosing the Right Cold-Rolled Grade

For simple bending and general fabrication choose DC01/SPCC. For deep drawing use DC04 or DC06 (SPCD/SPCE) with the appropriate r-value. If the part is load-bearing, select a structural grade such as S235JR-CR or HC340LA for higher yield strength. Always state the surface finish (bright or dull) and the required mechanical values, because these determine how the coil performs in your press.

Product Advantages for Press Shops and Appliance Makers

Cold-rolled steel earns its place in high-volume production because its consistent gauge and surface quality keep dies running without constant adjustment. Our coils offer tight thickness tolerance, controlled surface roughness and batch-to-batch mechanical consistency — the three properties that matter most to Polish press shops and appliance manufacturers. We can supply full hard coil for your own annealing line or annealed skin-passed coil ready for forming, and we support development batches with smaller coil weights before committing to program volumes. Because we are the mill, technical support and grade substitution advice come from the people who made the steel.

Quality Control & Certification

Every batch of material delivered from our Tianjin plant passes through a documented inspection routine: chemical composition analysis, tensile and yield testing, dimensional checks and, where applicable, hydrostatic or flattening tests. Each consignment ships with an EN 10204 3.1 mill test certificate (MTC) and batch traceability records, so your incoming inspection at Gdansk, Gdynia, Szczecin or any other EU port is straightforward. The factory operates under an ISO 9001:2015 quality management system and is independently audited by SGS and TUV Rheinland for production capacity and export reliability.

Inspection & Testing Before Shipment

Before any material leaves the plant it passes through a defined inspection gate. Dimensional checks are performed against the ordered specification, surface quality is inspected visually and with instruments where required, and the relevant mechanical and chemical tests are verified against the mill certificate. For pipe and tube products, hydrostatic and non-destructive testing results are reviewed against the standard’s acceptance criteria. Customers who request it can witness the inspection or receive photographs and video of the loaded goods before the vessel sails — a practical way to build confidence without travelling to China.

Export Documentation Included

Every order is shipped with a complete documentation set: commercial invoice, packing list, bill of lading, certificate of origin, and the EN 10204 3.1 mill test certificate with heat numbers and test results. Where your project requires third-party inspection, we can arrange SGS, TUV or Bureau Veritas inspection before loading, with the inspection report issued in English for easy clearance in the EU.

Cold-Rolled Steel Coils — Precise Dimensions, Clean Surface

Cold-rolled steel is hot-rolled strip that has been further reduced at ambient temperature, producing a thinner, stronger and dimensionally precise material with a clean, smooth surface. It is the preferred substrate for products that are painted, plated, deep-drawn or machined to tight tolerances. Sino East Steel supplies cold-rolled coils and sheets in thicknesses from 0.15 mm to 3.5 mm, widths from 600 mm to 1,800 mm, in grades DC01 to DC06 (EN 10130), SPCC to SPCE (JIS G3141), and structural grades like S235JR-CR. Material can be delivered as full hard, skin-passed or annealed per your forming requirements, with slit coils and cut-to-length sheets available.

Cold Rolling and Annealing

Hot-rolled pickled coil is cold-reduced on tandem mills to the target gauge, which work-hardens the steel. For forming applications the coil is then annealed in a controlled atmosphere to restore ductility, and skin-passed to achieve the final surface finish and flatness. The result is a product with tight thickness tolerance (±0.02 mm typical), excellent surface quality and consistent mechanical properties across the full coil length.

Applications

Cold-rolled steel is consumed by manufacturers of automotive components, appliances, office furniture, lockers and shelving, electrical enclosures, lighting fittings, drums and containers, and as the base for galvanized, color-coated and tin-plated products. Polish manufacturers of metal furniture and household goods rely on cold-rolled coil for its consistent gauge, which keeps pressing and forming dies running without adjustment.

Choosing the Right Cold-Rolled Grade

For simple bending and general fabrication choose DC01/SPCC. For deep drawing use DC04 or DC06 (SPCD/SPCE) with the appropriate r-value. If the part is load-bearing, select a structural grade such as S235JR-CR or HC340LA for higher yield strength. Always state the surface finish (bright or dull) and the required mechanical values, because these determine how the coil performs in your press.

Product Advantages for Press Shops and Appliance Makers

Cold-rolled steel earns its place in high-volume production because its consistent gauge and surface quality keep dies running without constant adjustment. Our coils offer tight thickness tolerance, controlled surface roughness and batch-to-batch mechanical consistency — the three properties that matter most to Polish press shops and appliance manufacturers. We can supply full hard coil for your own annealing line or annealed skin-passed coil ready for forming, and we support development batches with smaller coil weights before committing to program volumes. Because we are the mill, technical support and grade substitution advice come from the people who made the steel.

Quality Control & Certification

Every batch of material delivered from our Tianjin plant passes through a documented inspection routine: chemical composition analysis, tensile and yield testing, dimensional checks and, where applicable, hydrostatic or flattening tests. Each consignment ships with an EN 10204 3.1 mill test certificate (MTC) and batch traceability records, so your incoming inspection at Gdansk, Gdynia, Szczecin or any other EU port is straightforward. The factory operates under an ISO 9001:2015 quality management system and is independently audited by SGS and TUV Rheinland for production capacity and export reliability.

Inspection & Testing Before Shipment

Before any material leaves the plant it passes through a defined inspection gate. Dimensional checks are performed against the ordered specification, surface quality is inspected visually and with instruments where required, and the relevant mechanical and chemical tests are verified against the mill certificate. For pipe and tube products, hydrostatic and non-destructive testing results are reviewed against the standard’s acceptance criteria. Customers who request it can witness the inspection or receive photographs and video of the loaded goods before the vessel sails — a practical way to build confidence without travelling to China.

Export Documentation Included

Every order is shipped with a complete documentation set: commercial invoice, packing list, bill of lading, certificate of origin, and the EN 10204 3.1 mill test certificate with heat numbers and test results. Where your project requires third-party inspection, we can arrange SGS, TUV or Bureau Veritas inspection before loading, with the inspection report issued in English for easy clearance in the EU.

Why European Buyers Source This Product from Sino East Steel

Importing steel from China to Poland is a routine, well-understood process when you work with a manufacturer that has done it hundreds of times. Sino East Steel combines factory-direct pricing with export experience across the EU, so you avoid the margin stack of trading companies and the documentation delays that slow down first-time imports. Our export team prepares commercial invoices, packing lists, certificates of origin, and the EN 10204 3.1 mill certificates your quality department and customs broker expect. We also coordinate vessel booking from Tianjin/Xingang to Baltic ports, and for regular customers we can hold production slots so repeat orders keep your warehouse stocked without interruption.

Because we are the manufacturer, specification changes, coating requirements, packing instructions and delivery dates are agreed directly with the people who control the production line. This transparency is what distributors and contractors in Poland value most: one accountable partner, one set of documents, and material that matches the sample on every shipment.

Packaging & Delivery to Poland and the EU

Products are packed in seaworthy export condition: steel strapping, waterproof wrapping, and wooden or steel pallets where required, with clear marking for safe handling. For pipe and tube orders we use the standard export bundle format with plastic end caps on request. Sea freight to Polish and Baltic ports (Gdansk, Gdynia, Szczecin, Klaipeda) is arranged from Tianjin or Xingang port, with typical lead times of 15–25 days after production. FCL and LCL options are both available, and mixed-container consolidation is offered for regular customers who combine several product lines in one delivery.

Customization & Value-Added Services

Beyond standard supply, our finishing lines can prepare material for your exact production step: cutting to length, drilling, bevelling, threading, coating, marking and custom bundling per your drawings. Packaging can be adapted to your handling equipment — pallets, frames, slings or individual protective wrapping — and private labeling is available for distributors who resell under their own brand. For customers with regular monthly programs, we schedule production slots so that reorder quantities arrive on time, allowing you to run leaner stock without risking supply gaps on your own production line.

Technical Support & After-Sales Service

Our export engineers support you from specification to installation: confirming grade and size selections, advising on coatings and packing for your climate and handling equipment, and answering technical questions from your quality department. After delivery, we keep the batch records on file and can issue additional documentation, arrange replacement paperwork, or support you in the rare case of a claim. For Polish customers this means a single point of contact who knows your orders, your specifications and your delivery history — service that trading intermediaries rarely match.

Storage & Handling on Site

To protect the material between delivery and installation, store it off the ground on sleepers, keep it dry and allow air circulation between layers. Galvanized products should be separated from black steel to avoid zinc staining, and painted or polished surfaces should keep their protective wrapping until installation. When lifting, use fabric slings or spreader bars for long lengths to avoid damage. Our packing lists indicate bundle weights and lifting points, and our export team can advise on safe unloading at your warehouse or construction site.

How to Order & Request a Quotation

To receive a firm quotation, please send your required specification: grade and standard, dimensions, quantities (in tons or pieces), end use, and the destination port in Poland or the EU. Our export team replies within 24 hours with pricing, availability and a proposed shipping schedule. We work with T/T and L/C payment terms, and for established EU customers longer payment arrangements can be discussed on a project basis.

Frequently Asked Questions

What is the difference between full hard and annealed cold-rolled coil?

Full hard coil is cold-reduced without annealing — it has high strength but is not suitable for forming. Annealed (and skin-passed) coil has restored ductility and is the standard choice for pressing, deep drawing and general fabrication.

Do you supply cold-rolled coil with surface oiling?

Yes, coils can be supplied lightly oiled or dry per your storage and handling preference. Oiled material protects the surface during transit and storage in humid conditions.

What documents do you provide with each shipment?

Each shipment includes the EN 10204 3.1 mill test certificate, packing list, commercial invoice and bill of lading. Inspection reports and third-party certificates (SGS, TUV, Bureau Veritas) can be arranged before loading if your project requires them.

Can you supply to Polish and European standards?

Yes. We regularly export to EN and DIN specifications used across the EU, including EN 10219, EN 39, EN 10210, EN 10305 and DIN 2440, in addition to ASTM and API standards. Tell us the standard your project specifies and we will quote accordingly.

What are your MOQ and lead times?

MOQ depends on the product and size — typically from 1 to 10 tons for standard lines. Production and shipping to Polish ports normally takes 15–25 days from order confirmation.

Do you ship to Polish ports and handle customs paperwork?

Yes. We ship FOB Tianjin/Xingang, CIF or CFR to Gdansk, Gdynia, Szczecin and other Baltic ports, and we prepare the export documentation (commercial invoice, packing list, bill of lading, certificate of origin, mill certificates) needed for import clearance in Poland.

Can we arrange a pre-shipment inspection?

Yes. Third-party inspection by SGS, TUV, Bureau Veritas or your own representative can be arranged before loading, and the inspection report is provided before the vessel departs.

Do you offer samples before a full order?

For most products we can provide small samples or cut pieces so your quality department can verify the material. Sample cost is credited against the first order for regular customers.

Before any material leaves the plant it passes through a defined inspection gate. Dimensional checks are performed against the ordered specification, surface quality is inspected visually and with instruments where required, and the relevant mechanical and chemical tests are verified against the mill certificate. For pipe and tube products, hydrostatic and non-destructive testing results are reviewed against the standard’s acceptance criteria. Customers who request it can witness the inspection or receive photographs and video of the loaded goods before the vessel sails — a practical way to build confidence without travelling to China.

Export Documentation Included

Every order is shipped with a complete documentation set: commercial invoice, packing list, bill of lading, certificate of origin, and the EN 10204 3.1 mill test certificate with heat numbers and test results. Where your project requires third-party inspection, we can arrange SGS, TUV or Bureau Veritas inspection before loading, with the inspection report issued in English for easy clearance in the EU.

Why European Buyers Source This Product from Sino East Steel

Importing steel from China to Poland is a routine, well-understood process when you work with a manufacturer that has done it hundreds of times. Sino East Steel combines factory-direct pricing with export experience across the EU, so you avoid the margin stack of trading companies and the documentation delays that slow down first-time imports. Our export team prepares commercial invoices, packing lists, certificates of origin, and the EN 10204 3.1 mill certificates your quality department and customs broker expect. We also coordinate vessel booking from Tianjin/Xingang to Baltic ports, and for regular customers we can hold production slots so repeat orders keep your warehouse stocked without interruption.

Because we are the manufacturer, specification changes, coating requirements, packing instructions and delivery dates are agreed directly with the people who control the production line. This transparency is what distributors and contractors in Poland value most: one accountable partner, one set of documents, and material that matches the sample on every shipment.

Packaging & Delivery to Poland and the EU

Products are packed in seaworthy export condition: steel strapping, waterproof wrapping, and wooden or steel pallets where required, with clear marking for safe handling. For pipe and tube orders we use the standard export bundle format with plastic end caps on request. Sea freight to Polish and Baltic ports (Gdansk, Gdynia, Szczecin, Klaipeda) is arranged from Tianjin or Xingang port, with typical lead times of 15–25 days after production. FCL and LCL options are both available, and mixed-container consolidation is offered for regular customers who combine several product lines in one delivery.

Customization & Value-Added Services

Beyond standard supply, our finishing lines can prepare material for your exact production step: cutting to length, drilling, bevelling, threading, coating, marking and custom bundling per your drawings. Packaging can be adapted to your handling equipment — pallets, frames, slings or individual protective wrapping — and private labeling is available for distributors who resell under their own brand. For customers with regular monthly programs, we schedule production slots so that reorder quantities arrive on time, allowing you to run leaner stock without risking supply gaps on your own production line.

Technical Support & After-Sales Service

Our export engineers support you from specification to installation: confirming grade and size selections, advising on coatings and packing for your climate and handling equipment, and answering technical questions from your quality department. After delivery, we keep the batch records on file and can issue additional documentation, arrange replacement paperwork, or support you in the rare case of a claim. For Polish customers this means a single point of contact who knows your orders, your specifications and your delivery history — service that trading intermediaries rarely match.

Storage & Handling on Site

To protect the material between delivery and installation, store it off the ground on sleepers, keep it dry and allow air circulation between layers. Galvanized products should be separated from black steel to avoid zinc staining, and painted or polished surfaces should keep their protective wrapping until installation. When lifting, use fabric slings or spreader bars for long lengths to avoid damage. Our packing lists indicate bundle weights and lifting points, and our export team can advise on safe unloading at your warehouse or construction site.

How to Order & Request a Quotation

To receive a firm quotation, please send your required specification: grade and standard, dimensions, quantities (in tons or pieces), end use, and the destination port in Poland or the EU. Our export team replies within 24 hours with pricing, availability and a proposed shipping schedule. We work with T/T and L/C payment terms, and for established EU customers longer payment arrangements can be discussed on a project basis.

Frequently Asked Questions

What is the difference between full hard and annealed cold-rolled coil?

Full hard coil is cold-reduced without annealing — it has high strength but is not suitable for forming. Annealed (and skin-passed) coil has restored ductility and is the standard choice for pressing, deep drawing and general fabrication.

Do you supply cold-rolled coil with surface oiling?

Yes, coils can be supplied lightly oiled or dry per your storage and handling preference. Oiled material protects the surface during transit and storage in humid conditions.

What documents do you provide with each shipment?

Each shipment includes the EN 10204 3.1 mill test certificate, packing list, commercial invoice and bill of lading. Inspection reports and third-party certificates (SGS, TUV, Bureau Veritas) can be arranged before loading if your project requires them.

Can you supply to Polish and European standards?

Yes. We regularly export to EN and DIN specifications used across the EU, including EN 10219, EN 39, EN 10210, EN 10305 and DIN 2440, in addition to ASTM and API standards. Tell us the standard your project specifies and we will quote accordingly.

What are your MOQ and lead times?

MOQ depends on the product and size — typically from 1 to 10 tons for standard lines. Production and shipping to Polish ports normally takes 15–25 days from order confirmation.

Do you ship to Polish ports and handle customs paperwork?

Yes. We ship FOB Tianjin/Xingang, CIF or CFR to Gdansk, Gdynia, Szczecin and other Baltic ports, and we prepare the export documentation (commercial invoice, packing list, bill of lading, certificate of origin, mill certificates) needed for import clearance in Poland.

Can we arrange a pre-shipment inspection?

Yes. Third-party inspection by SGS, TUV, Bureau Veritas or your own representative can be arranged before loading, and the inspection report is provided before the vessel departs.

Do you offer samples before a full order?

For most products we can provide small samples or cut pieces so your quality department can verify the material. Sample cost is credited against the first order for regular customers.
