T3 Temper ETP Tin Coated Electrolytic Tinplate Coil The Top Solution For Food And Beverage Packaging JIS G3303 EN10203
Tin mill products encompass several key varieties: electrolytic tinplate, electrolytic chromium coated steel (known as tin free steel or TFS), and Black Plate. Tinplate consists of a thin steel sheet coated with tin, imparting a glossy metallic finish and enhancing properties like corrosion resistance and paintability. TFS, on the other hand, is steel plated with a thin layer of chromium and chromium oxide, delivering similar aesthetic appeal and robust qualities in terms of protection from corrosion and suitability for painting.
Modern tinplate is typically crafted from cold-rolled, low carbon steel, meticulously coated with pure tin on both sides. This composite material synergizes the inherent strength and malleability of steel with the superior corrosion resistance, weldability, and visual appeal of tin. Such tinplate finds extensive applications across various industries, particularly in the food sector for cans and packaging. It also serves in non-food applications such as aerosol cans, bottle caps, gas-containing beverage containers, as well as in the manufacturing of home appliances, toys, stationery, and engineering materials.
Excellent Corrosion Resistance
By selecting a proper coating weight, appropriate corrosion resistance is obtained against container contents.
Excellent Paintability & Printability
Printing is beautifully finished using various lacquers and inks.
Excellent Solderability & Weldability
TIN PLATE is widely used for making various types of cans by soldering or welding.
Excellent Formability & Strength
By selecting a proper temper grade, appropriate formability is obtained for various applications as well as the required strength after forming.
Beautiful Appearance
Electrolytic ETP is characterized by its beautiful metallic luster. Products with various kinds of surface roughness are produced by selecting the surface finish of the substrate steel sheet.

The hardness is the average value of 2 samples, allowing 1 of them to exceed the specified allowable range by 1 unit. |

a The yield strength is a reference value determined as required. b Yield strength is the average value of the two samples. The sample is P5 in GB/T 228, and the direction of the sample is transverse. c Due to the thickness thinning effect, the elongation is too low and the yield strength cannot be measured. In this case, the yield strength is replaced by the tensile strength. d For the tensile test, the width of the parallel part of the sample is (12.5±1) mm, and the standard distance L0=50mm. Before the test. The sample should be artificially aged for 20min at 200℃. |
