PPGI Coils

Polish producers of roofing sheets, sandwich panels, wall cladding and white goods need a PPGI coil supplier who delivers consistent colour, coating and formability. Sino East Steel is a pre-painted galvanized coil (PPGI) manufacturer and factory in Tianjin, exporting colour-coated coils to EN 10169, ASTM A755 and JIS G3321 standards in the most requested RAL colours — RAL 3009, RAL 3011, RAL 5002, RAL 6005, RAL 7016, RAL 8017 and many more — with PE, SMP and PVDF paint systems. As the factory, we control the galvanized substrate, the paint film thickness and the coil packing, giving Polish processors colour stability and yield they can plan production around.
PPGI Coils — Prepainted Steel for Architecture and IndustryPPGI (prepainted galvanized iron) coil is galvanized steel sheet coated with a primer and a finish paint layer on a continuous paint line. The result is a durable, color-consistent surface that arrives ready for roll forming into roofing sheets, wall cladding, gutters, and a wide range of architectural and industrial profiles. Sino East Steel supplies PPGI coils in thicknesses from 0.18 mm to 1.2 mm, widths from 600 mm to 1,250 mm, in polyester (PE), silicon-modified polyester (SMP), PVDF and high-durability finishes, with a full range of standard RAL colors and custom color matching. Base metal can be specified as regular galvanized, galvalume (AZ) or Z275 grade to suit the project environment.
Continuous Coil Coating LineGalvanized coil is cleaned, chemically treated and primed on a continuous line, then cured in an oven before a finish coat is applied and cured again. The two-coat system provides excellent adhesion, flexibility for roll forming and resistance to UV and weathering. Reverse-side coating is applied as standard, and each batch is checked for color consistency, film thickness (typically 20–25 micron total), hardness and adhesion before packing.
ApplicationsPPGI coil is the raw material for the roofing and cladding sector across Poland: trapezoidal and standing-seam roof sheets, sandwich panel facings, wall cladding profiles, corrugated sheets for agricultural buildings, garage doors, fence panels, and indoor liner profiles. It is also used in appliances, electrical enclosures and furniture components where a factory-quality painted surface replaces costly post-painting.
Selecting the Right Paint SystemFor standard roofing and cladding, polyester (PE) gives the best value with good durability. For coastal or industrial environments, and where the warranty period is long, SMP or PVDF coatings provide superior UV and chemical resistance. Always confirm the reverse-side coating (usually gray or epoxy) and the film thickness with the mill — these details determine the sheet’s service life on Polish buildings.

Specification Deep-Dive for PPGI CoilsPPGI (pre-painted galvanized iron) coil consists of a galvanized steel substrate, a chemical pre-treatment layer and a paint system applied on a coil coating line. The substrate is normally DX51D to DX54D with Z80 to Z275 zinc coating; the paint system is polyester (PE), silicone modified polyester (SMP), polyvinylidene fluoride (PVDF) or high-durability polyurethane. Paint film thickness is typically 20-25 microns total (top coat plus primer) for PE and up to 25-30 microns for SMP/PVDF, with a 5-7 micron back coat. Key properties verified per coil: pencil hardness, T-bend adhesion (2T-3T typical for PE), impact resistance, salt spray resistance and colour difference (ΔE) between coils. We produce in the most requested RAL colours and any custom code, with batch colour records so reorders match. Thicknesses from 0.17 mm to 1.2 mm, widths up to 1250 mm, and coil weights up to 8 tons are available. For Polish roofing, cladding and panel producers, consistent colour from coil to coil and stable formability are the two properties that protect their product reputation — both are documented in the certificate set we provide with every delivery.
Ordering PPGI Coils for Polish Roofing and PanelsFor PPGI, specify the substrate (DX51D–DX54D galvanized), coating class (Z80–Z275), paint system (PE, SMP, PVDF), RAL colour, thickness, width and quantity. We produce colour coils against your exact RAL code and confirm colour consistency with batch records, so your profiling line receives coils that match from order to order. Sample coils for colour approval are available before series production.
Quality Control & CertificationEvery 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.
Export Documentation IncludedEvery 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 SteelImporting 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 EUProducts 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 ServicesBeyond 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 ServiceOur 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.
Inspection & Testing Before ShipmentBefore 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.
