Color Coated Tinplate Roofing Sheet
Electrolytic tinplate sheet with a printed passivated surface for roofing and panels
Color coated tin roofing sheet is electrolytic tinplate, a cold rolled low carbon steel sheet coated on both sides with commercial pure tin and then finished in a bright, stone or silver surface with passivation treatment. It is specified by roofing panel fabricators and decorated container converters who want a light gauge steel sheet that carries print and resists rust without a separate paint line. Buying the sheet already tinned and passivated removes the coating step that thin steel normally needs before it can be formed, seamed and fixed. Material runs 0.15~0.50mm and can be ordered against GB/T 2520-2008, JIS G3303-2008, DIN EN 10203-1991 or ASTM A623M-2011.

Why It Is Specified
Key Benefits of Color Coated Tin Roofing Sheet
Tin Layer Does the Corrosion Work
Commercial pure tin on both faces prevents corrosion and rust so the steel core keeps its strength. Coating weight is selectable across the 1.1~11.2g/m2 range to match how exposed the finished panel will be.
Gauge Held to a Tight Tolerance
Sheet is supplied from 0.15~0.50mm with a thickness tolerance of +/- 0.01 mm, which keeps roll former and press brake settings stable across a whole delivery.
Surface Ready for Printing
Bright, stone and silver finishes are passivated and oiled with DOS oil, so the face accepts lithographic ink and decoration without a primer coat applied at your end.
Steel Strength With Tin Behavior
The sheet combines the strength and formability of steel with the corrosion resistance, solderability and appearance of tin, so panels can be folded, seamed and soldered on existing equipment.
Four Specifications From One Stock
The same material is released against GB/T 2520-2008, JIS G3303-2008, DIN EN 10203-1991 or ASTM A623M-2011, so a drawing written to any of them can be quoted without changing supplier.
Problems It Solves
What This Material Removes From Your Process
Painting Thin Sheet Before It Can Be Used
Bare cold rolled sheet has to be protected before forming, which adds a line and a drying time. Tinplate arrives already coated on both sides and passivated, so forming can start on delivery.
Forming Settings Drifting Across a Batch
Gauge variation makes roll formers and presses need constant adjustment. A +/- 0.01 mm thickness tolerance keeps the setting valid through the run.
Buying Against a Foreign Specification
A customer drawing may call GB, JIS, DIN or ASTM. The sheet is released against GB/T 2520-2008, JIS G3303-2008, DIN EN 10203-1991 or ASTM A623M-2011 so one order covers the requirement.
Surfaces That Reject Ink
Untreated steel needs preparation before printing. The bright, stone or silver passivated finish is supplied print ready, which removes a preparation stage in the decoration shop.
Application Scenarios
Where It Is Used
Roofing and Cladding Panels
Light gauge formed panels where a rugged light proof sheet with a decorative face is wanted and the panel has to be folded and fixed on site.
Food Packaging Containers
Can bodies, ends and closures where the sealing, preservation and non toxic behavior of tinplate are the reason the material is specified.
Pharmaceutical Packaging
Tins and closures for medical goods that need a light proof metal wall and a clean, passivated inner surface.
Commodity and Gift Containers
Printed tins and decorative boxes that rely on the metal decoration effect of tinplate rather than an applied paint finish.
Instrument and Industrial Packaging
Protective cases and industrial packs where antioxidant behavior and mechanical ruggedness matter more than weight.

Comparison
Color Coated Tin Roofing Sheet Against the Alternatives
| Pre painted galvanized sheet | Tinplate carries a metallic tin surface that is non toxic and solderable, so it suits food contact and soldered seams where an organic paint film does not. |
|---|---|
| Bare cold rolled steel sheet | The tin layer on both faces prevents corrosion and rust in transit and in service, so the sheet does not need protecting before it is formed. |
| Aluminum sheet of the same gauge | The steel base gives higher strength at 0.15~0.50mm and the tinned surface accepts soldering, which aluminum of the same thickness does not. |
Use Guide
Specifying Handling and Welding Notes
- State the finished panel or blank size so the sheet is sheared to length rather than trimmed in your shop
- Pick the tin coating weight for the exposure the panel will see and keep the heavier end of 1.1~11.2g/m2 for humid duty
- Use a lower temper such as T2 or T2.5 where the panel is deeply formed and a higher temper where stiffness matters
- Keep the sheets in the original packing until forming so the DOS oil film stays intact
- Store stacks off the floor in a dry store because passivation protects the tin layer but does not replace dry storage
- Ask for the mill test certificate with the shipment so the standard and coating weight are on record
