Electrolytic Tinplate

Food canning, aerosol, paint and packaging industries across Poland depend on food-safe electrolytic tinplate with consistent coating weight and surface finish. Sino East Steel is a tinplate manufacturer and factory supplying ETP sheets, coils and strips to ASTM A623, EN 10202 and JIS G3303 standards, with tin coating classes from 1.0 to 11.2 g/m² and single or double cold-rolled temper. Buying direct from our factory gives Polish packagers controlled batch chemistry, precise coating for corrosion protection and printability, and full food-contact documentation.
Electrolytic Tinplate — Precision Coating for Packaging and IndustryElectrolytic tinplate is cold-rolled low-carbon steel strip coated with a thin layer of pure tin by electroplating. The tin layer provides corrosion resistance, a bright surface and food-safe contact properties, making tinplate the standard material for food cans, beverage ends, closures, batteries and a wide range of industrial packaging. Sino East Steel supplies electrolytic tinplate in thicknesses from 0.15 mm to 0.55 mm and widths from 600 mm to 1,100 mm, with tin coatings from 1.1 to 11.2 g/m² per side, in single and double reduced tempers, as sheets or coils. Material is produced to JIS G3303, EN 10202 and GB/T 2520 with full surface and coating certification.
Electrolytic Tinning LineCold-rolled strip is cleaned, annealed and skin-passed, then passed through an electroplating line where tin is deposited from electrolyte solution onto both surfaces. The coated strip is reflowed to fuse the tin into a smooth bright layer, passivated for stability, and oiled to protect the surface. Coating weight is controlled by current density and measured per side, so each coil meets the specified tin distribution before sheeting or recoiling.
ApplicationsTinplate is used for food and beverage cans, aerosol cans, fish and meat packaging, metal closures and crowns, dry batteries, electronic components, and decorative and industrial containers. For Polish can makers and packaging converters, consistent gauge and coating weight are critical — they determine drawability on high-speed can lines and final corrosion performance in contact with food products.
Selecting Tinplate Grade and TemperSelect the temper (T1–T5 or DR grades) according to the forming severity: soft tempers for deep-drawn bodies, harder tempers for ends and closures. Choose the tin coating weight by the corrosivity of the contents — lighter coatings (2.8/2.8 g/m²) for dry goods, heavier coatings (5.6/5.6 and above) for acidic or aggressive products. Specify whether you need sheets, coils or coils for shearing, plus the required surface finish (bright, stone or matte).

Specification Deep-Dive for Electrolytic TinplateElectrolytic tinplate (ETP) is cold-rolled low-carbon steel coated with a thin layer of pure tin by electroplating, providing corrosion resistance and a food-safe surface. Key specifications: base steel MR (low residual, for food) or L (for chemical), temper T1-T5 (hardness class), tin coating E2.8-E11.2 (g/m², per side or total), and surface finishes bright, stone and matte. Coating weight is verified by the coulometric method and stated on the certificate. Sheet sizes from 700×500 mm to 1200×1200 mm (or coil form) with thicknesses from 0.15 mm to 0.55 mm. Mechanical properties follow the temper class, balancing formability and strength for can bodies, ends and closures. Packaging: sheets interleaved and palletised, coils wrapped with edge protection, with food-contact declarations available. Polish canners, aerosol and paint manufacturers use ETP for its consistent coating and printability — we document coating weight, temper and chemistry per lot and can supply sample sheets for print and draw testing before series production.
Ordering Electrolytic TinplateSpecify the base steel (MR or L), temper, tin coating weight (E2.8–E11.2), sheet size or coil dimensions and surface finish (bright, stone, matte). We confirm coating weights, packaging and food-contact documentation for canning lines, and supply sample sheets for print and draw tests 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.
