Color Coated Tin Roofing Sheet
Electrolytic tinplate sheet with a printed passivated surface for roofing and panels
Specifications
Tinplate Coil/Strip/Sheet
Coated Tinplate Sheet SPTE Electrolytic Tin Plate
Electrolytic tin coated steel sheet for printed can bodies ends and closures
Coated tinplate sheet is cold rolled low carbon steel electroplated with commercial pure tin on both faces then passivated and oiled before shearing to sheet size. Can makers, lithographers and packaging converters specify it in SPCC, MR or SPCH material against GB/T 2520-2008, JIS G3303-2008, DIN EN 10203-1991 or ASTM A623M-2011. Receiving it already sheared to the press sheet size in the ordered temper and tin coating weight removes the coil decoiling and shearing step that ties up a converter line and the offcut that comes with buying wide material. Thickness runs 0.15-0.50mm with a tolerance of plus or minus 0.01 mm so print registration and double seam dimensions stay repeatable across the run.

Why It Is Specified
Key Benefits of Coated Tinplate Sheet
Tin Coating Weight Matched to the Contents
Tin coating is available from 1.1 to 11.2 g/m2 on both faces. Dry goods can run on a light coating while acidic or aggressive contents take a heavier one, so you are not paying for tin the pack does not need.
Thickness Held Within 0.01 mm
Sheets are supplied 0.15-0.50mm thick with a thickness tolerance of plus or minus 0.01 mm. That keeps press feeding, flanging and double seam dimensions consistent from the first sheet to the last.
Passivated Surface Ready for Lithography
Bright, stone or silver finish is supplied with passivation treatment and DOS oil. The passivation film holds coating and ink adhesion and the oil protects the tin surface until the sheets reach the coating line.
Four Tinplate Standards Accepted on One Order
The same material can be ordered against GB/T 2520-2008, JIS G3303-2008, DIN EN 10203-1991 or ASTM A623M-2011 so a buyer serving several export markets does not have to split the order between suppliers.
Steel Strength with Tin Corrosion Resistance
The steel base carries the strength and formability while the pure tin layer brings corrosion resistance, solderability and a decorative metallic surface. The combination is non-toxic and stays ductile enough to draw and flange.
Problems It Solves
What This Material Removes From Your Process
Shearing Coil In House Before Every Print Run
Converters who buy coil have to slit and shear before anything can be printed. Sheet supplied at the finished press size takes that step out of the plant and frees the cut to length line for other work.
Print Registration Drifting With Gauge Variation
Uneven gauge upsets feeding and registration on a sheet fed press. A thickness tolerance of plus or minus 0.01 mm across the 0.15-0.50mm range keeps the stack consistent.
Over Specifying Tin on Low Risk Packs
Buying one heavy coating weight for every pack wastes tin on dry and neutral contents. A coating range of 1.1 to 11.2 g/m2 lets each pack be ordered at the weight the contents actually require.
Certificate Sets That Do Not Match the Market
Packaging sold into different regions is checked against different standards. Ordering against GB/T 2520-2008, JIS G3303-2008, DIN EN 10203-1991 or ASTM A623M-2011 keeps documentation aligned with the destination.
Application Scenarios
Where It Is Used
Food Can Bodies and Ends
Sheets printed and coated then cut into body blanks and end shells for food cans where sealing, preservation and light exclusion matter.
Pharmaceutical and Health Product Tins
Small hinged and slip lid tins where a non-toxic metal pack protects the contents from light and moisture.
Printed Commodity and Gift Packaging
Confectionery tins, tea caddies and promotional boxes that rely on the metal decoration and exquisite printing the tin surface accepts.
Instrument and Component Packaging
Rugged tin boxes for instruments, tooling and small parts that have to survive handling and transport without crushing.
Industrial Pails Cans and Closures
Paint, adhesive, sealant and chemical containers where the pack has to resist the contents and carry a printed label directly on the metal.

Comparison
Coated Tinplate Sheet Against the Alternatives
| Uncoated cold rolled black plate | The electroplated tin layer adds corrosion resistance and solderability that bare cold rolled sheet does not have, which is what makes the pack suitable for food contact. |
|---|---|
| Aluminium sheet for packaging | Tinplate keeps the higher strength and rigidity of a steel base, so thin walled bodies resist denting and stacking load. |
| Plastic packaging | Tinplate gives light exclusion, sealing and preservation in one material and takes printing directly on the metal without a separate label. |
| Tinplate bought as full coil | Sheet arrives at the press size so the converter skips decoiling and shearing and does not carry the offcut from a wide coil. |
Use Guide
Specifying Handling and Welding Notes
- Match the tin coating weight to the contents rather than buying one heavy weight for the whole range
- Pick a harder temper such as DR7 or DR8 where wall thickness is being reduced and a softer T2 or T3 where the blank is deep drawn
- Keep sheets stacked flat and dry because the DOS oil is transit protection and not a permanent barrier
- Degrease the surface to the level your coating line expects before printing or varnishing
- State the destination market standard on the order so the material is certified against GB/T JIS DIN EN or ASTM
- Confirm the sheet size against the press feed before production so the blank layout wastes as little as possible
Questions Buyers Ask
Coated Tinplate Sheet FAQ
What thickness and tolerance can you hold on tinplate sheet?
Thickness runs from 0.15mm to 0.50mm with a tolerance of plus or minus 0.01 mm. Sheet size is sheared to the press feed dimensions you specify.
Which tin coating weights are available?
Tin coating runs from 1.1 to 11.2 g/m2 electroplated on both faces. Tell us the contents and the shelf life you are targeting and we will confirm which weight fits.
What is the difference between BA and CA material?
BA is batch annealed and CA is continuous annealed, and both are available across the T2 to DR8 temper range. The choice affects formability and how the sheet behaves through drawing and flanging.
Which standards can the sheet be supplied against?
GB/T 2520-2008, JIS G3303-2008, DIN EN 10203-1991 and ASTM A623M-2011. Name the standard on the order so the material is certified to the one your market checks.
What surface finishes do you offer?
Bright, stone and silver finish, each with passivation treatment and DOS oil. The passivation film is there to hold coating and ink adhesion on the printing line.
What certifications does the material carry?
ISO9001, BV, SGS and RoHS. Confirm which documents your customs entry or customer audit needs and we will include them with the shipment.
Can you supply SPCC MR and SPCH on the same order?
Yes. All three materials are available, so a converter running food packs and industrial packs can take both on one shipment instead of splitting the order.
