Tinplate Coil/Strip/Sheet
Electrolytic Tinplate Coil SPTE ETP
Cold rolled low carbon steel strip tin coated on both sides for can and container making
Tinplate coil, also called SPTE or ETP, is cold rolled low carbon steel strip electroplated with commercially pure tin on both sides. Can makers, aerosol and closure lines, pharmaceutical packers and instrument case producers specify it when they need the strength and forming behavior of steel with the corrosion resistance, solderability and printable surface of tin. Ordering to a fixed temper and tin coating weight removes the guesswork that causes drawn bodies to split or ends to corrode after filling. Coils are supplied in defined thickness and width bands with passivation and DOS oil already applied, so the strip runs straight into a slitter or press line.

Why It Is Specified
Key Benefits of Tinplate Coil
Tin Coating Weight Chosen by Contents
Coating runs from 1.1 to 11.2g/m2 so a dry food can and an aggressive filling can be ordered on the same purchase order with different coating weights.
Temper Band Matched to the Forming Step
Tempers cover T2 through T5 and DR7 DR7M DR8, so deep drawn bodies, easy open ends and stiff closures each get the hardness they need.
Tight Gauge and Width Tolerance
Thickness holds to plus or minus 0.01 mm and width to 0~3mm, which keeps press feed and seam forming stable across the coil.
Four Reference Standards on One Product
Material is produced against GB/T 2520-2008, JIS G3303-2008, DIN EN 10203-1991 and ASTM A623M-2011, so buyers working to different regional specifications can order the same coil.
Surface Ready for Printing and Lacquering
Bright, stone or silver finish with passivation treatment and DOS oil gives a surface that accepts lacquer and lithographic printing without extra cleaning.
Coil Size Suited to decoiling Lines
Inside diameter of 420 or 508mm and coil weight of 1~5 MT match standard slitter and press feeders in most packaging plants.
Problems It Solves
What This Material Removes From Your Process
Coating Weight Guessed Rather Than Specified
Under coated strip corrodes after filling and over coated strip wastes tin. A stated coating between 1.1 and 11.2g/m2 lets you fix the figure against the product being packed.
Press Line Stopping on Gauge Variation
Feed problems and split bodies often trace back to thickness drift. Holding gauge to plus or minus 0.01 mm keeps forming force consistent down the coil.
Specifications Written to Different Regional Standards
Plants in different markets quote GB, JIS, DIN EN or ASTM. The same coil is produced against all four references so one order covers several destinations.
Surface Rejects After Printing
Passivation treatment and DOS oil applied at the mill protect the tin surface in transit so lacquer and ink adhere instead of lifting.
Application Scenarios
Where It Is Used
Food Can Bodies and Ends
Three piece and two piece food cans where the tin layer prevents corrosion and rust on the inside wall and the steel carries the seaming load.
Pharmaceutical and Health Product Containers
Tins and closures where non-toxic behavior and a sealed, light proof container protect the contents.
Commodity and Gift Packaging
Decorative boxes and tins where the metal surface takes exquisite printing and gives the finished container its own visual appeal.
Instrument and Industrial Packaging
Cases and pails for tools, instruments and industrial goods that need rugged walls rather than a fiber or plastic box.
Crown Caps Closures and Lids
Hard temper and DR grades formed into caps and lids where springback and edge strength decide sealing performance.

Comparison
Tinplate Coil Against the Alternatives
| Tin free steel TFS | Tinplate keeps solderability and the bright metallic surface that TFS loses, which matters for soldered side seams and uncoated decorative tins. |
|---|---|
| Aluminium can stock | The steel base gives higher strength for the same gauge and the coil is ordered in the same thickness band of 0.15~0.50mm used by existing steel press tooling. |
| Prepainted cold rolled sheet | The electroplated tin layer resists corrosion on both cut edges and formed radii rather than only where the paint film survives forming. |
Use Guide
Specifying Handling and Welding Notes
- Set the tin coating weight from the contents being packed rather than from price alone
- Pick a lower temper for deep drawn bodies and a DR grade for ends and closures
- Keep coils in dry storage and leave the DOS oil in place until the strip enters the line
- Allow for the 0~3mm width tolerance when setting slitter and feeder guides
- State the standard you work to so the coil ships against GB JIS DIN EN or ASTM
- Ask for the mill test certificate with the order so coating weight and temper are documented
Questions Buyers Ask
Tinplate Coil FAQ
What thickness and width can you supply in tinplate coil?
Thickness runs 0.15~0.50mm with a tolerance of plus or minus 0.01 mm, and width runs 600~1050mm with a tolerance of 0~3mm. Narrower strip is produced by decoiling from these widths.
Which tin coating weights are available?
Coating runs from 1.1 to 11.2g/m2. Tell us what the can will hold and we will confirm the coating weight for each side.
Which standards is the material produced against?
GB/T 2520-2008, JIS G3303-2008, DIN EN 10203-1991 and ASTM A623M-2011. Name the one your drawing calls out and the certificate is issued against it.
What is the difference between BA and CA temper?
BA is batch annealing and CA is continuous annealing. Both are available across the T2 to T5 range and the DR7, DR7M and DR8 grades, so the choice follows your forming route.
What coil inside diameter and weight will we receive?
Coil inside diameter is 420 or 508mm and coil weight is 1~5 MT. State your uncoiler limits and we will set both before production.
Is the surface ready for lithographic printing?
Coils ship in bright, stone or silver finish with passivation treatment and DOS oil. Remove the oil to your normal line procedure before lacquering or printing.
Can we get a sample coil before a full order?
Send the thickness, width, temper and coating weight you want to trial and we will confirm what can be released for testing on your line.
