Color Coated Tin Roofing Sheet
Electrolytic tinplate sheet with a printed passivated surface for roofing and panels
Specifications
Electrolytic Tinplate Coil Strip and Sheet
Electrolytic tinplate in coil strip and sheet form for can makers metal decorators and roofing fabricators
Tinplate, known on drawings as SPTE or ETP, is cold rolled low carbon steel sheet or strip electroplated with commercial pure tin on both sides. The steel carries the strength and formability while the tin layer supplies corrosion resistance, solderability and the bright surface that printing and lacquering need. This category groups the plain range of tinplate coil, tinplate strip and tinplate sheet with the coated tinplate coil, strip and sheet, the customized tinplate sheet cut to a blank size, and the tin roofing sheet and color coated tin roofing sheet used on light structures. It exists for buyers who are currently splitting can body stock, printed panel stock and roofing sheet across separate mills because no single supplier stocks all three forms.

What This Range Is For
Three Forms Bought From Three Suppliers
Can bodies come from coil, small stamped parts come from strip and printed panels come from sheet. When each form sits at a different mill the buyer runs three approvals and three inspection files for one material.
Corrosion Starting Before the Pack Is Filled
Bare cold rolled steel begins to rust in storage and sea transit. Tin is plated on both faces specifically to prevent corrosion and rust so blanks reach the filling line in usable condition.
Blanks Cracking During Drawing and Seaming
Packaging steel has to survive deep drawing and seaming without splitting. Tinplate keeps the formability of the low carbon steel base instead of trading it away for surface protection.
Seams That Will Not Take Solder
Side seams and closures depend on a solderable surface. The pure tin coating gives the solderability that a painted or plain steel surface cannot.
Standard Blank Sizes Generating Scrap
Buying a standard sheet size and trimming to the blank throws away steel on every press stroke. Customized tinplate sheet is released at the size your blanking line actually runs.
Who Buys It
Buyers Who Order From This Range
- Food and beverage can makers buying body and end stock in both coil and sheet
- Metal decorating and lithography shops that feed coated tinplate sheet through a printing press
- Aerosol chemical and general line packaging producers specifying tin coated steel by finished blank size
- Roofing and light building contractors sourcing tin roofing sheet and color coated tin roofing sheet
- Pail drum and closure manufacturers who solder or double seam the finished container
- Distributors supplying tinplate strip to small stamping and pressing workshops
Core Advantages
Why Source This Range From Tianyu Metal
Coil Strip and Sheet From One Range
The same tinplate specification is released as coil for decoiling lines, strip for stamping presses and sheet for blanking lines so one approval covers every form on the bill of material.
Tin Plated on Both Faces
Commercial pure tin is applied to both sides, so the inner face that meets the contents is protected as well as the outer face that carries the print.
Plain Coated and Color Coated in the Same Category
Plain tinplate, coated tinplate and color coated tin roofing sheet sit together, which lets a fabricator move between bare and finished surfaces without changing supplier.
Steel Behavior With a Tin Surface
You keep the strength and formability of cold rolled low carbon steel and add corrosion resistance, solderability and appearance from the tin layer.
Cut to Your Blank Instead of a Standard Sheet
Customized tinplate sheet is released against your length and width so the press works to your nesting plan rather than the mill standard.
Documented on Arrival
Material ships with a mill test certificate to EN 10204 so the tinplate on the line matches the tinplate on the purchase order.
Application Scenarios
Where This Range Ends Up
Food and Beverage Can Bodies and Ends
Round and shaped can bodies, ends and easy open components where the inside face must resist corrosion and the seam must solder.
Aerosol and Chemical Containers
Cans and closures for fillers who need a steel wall that takes internal pressure and a plated surface that resists the contents.
Printed and Lithographed Packaging
Gift tins, biscuit tins and promotional packaging where coated tinplate sheet goes straight onto a metal decorating line.
Roofing and Wall Cladding Panels
Tin roofing sheet and color coated tin roofing sheet on sheds, canopies and low rise buildings where a coated steel panel is fixed straight to purlins.
Caps Closures and Crown Corks
High volume stamped closures blanked from tinplate coil and strip where consistent thickness keeps the press tooling stable.
Small Stamped and Formed Components
Brackets, clips and housings pressed from tinplate strip where a protected surface removes a downstream plating step.
Buying Guide
What To State When You Order
State the designation you specify to, SPTE or ETP, together with the temper you need for drawing or for stiffness
Give thickness and width for coil and strip, and finished length and width for sheet if you want blanks rather than standard sheets
Say whether you need plain tinplate, coated tinplate or color coated roofing sheet, and name the color for the roofing range
Confirm the surface condition you print, lacquer or solder over so the material is released in the right finish
Name the form the line takes, coil for decoiling, strip for a stamping press or sheet for a blanking line, and the coil inside diameter your decoiler accepts
Ask for the mill test certificate and state the packing you need for sea freight so sheet edges and coil edges stay protected

Tinplate Coil/Strip/Sheet FAQ
What do SPTE and ETP mean on a tinplate specification?
They are the common designations for electrolytic tinplate. Both describe cold rolled low carbon steel sheet or strip that has been electroplated with commercial pure tin on both sides.
Can coil strip and sheet go on one order?
Yes. All three forms sit in this category, so a can maker can take coil for the body line, strip for the closure press and sheet for the printing line under a single purchase order.
Why specify tinplate instead of plain cold rolled steel?
Plain cold rolled steel gives you strength and formability but no surface protection. Tinplate adds corrosion resistance, solderability and a bright appearance without giving up the behavior of the steel base.
Do you supply coated and color coated tinplate?
Yes. Coated tinplate coil, coated tinplate strip and coated tinplate sheet are stocked alongside the plain range, and the roofing range includes both tin roofing sheet and color coated tin roofing sheet.
Is tinplate solderable for can side seams?
The tin layer is what gives tinplate its solderability, which is one of the reasons it is used for side seams and closures on cans and drums.
Can you cut sheet to our blank size?
Customized tinplate sheet is cut to the length and width you nominate. Send the blank dimensions and the quantity per size and we will confirm what can be released against them.
