CHARACTERISTICS OF TIN-PLATED STRIPS
Tin-plated strip is characterized by a tin coating that protects the steel against corrosion and prevents deterioration of the base material. The chemical composition of tin-plated strip is determined by the maximum weight percentage for Type A steels or Type B steels and is governed by the EN 10202 standard for cold-rolled steels for packaging. For details of each of these, please refer to the product data sheet section.
The approximate density of tin-plated strip is 7.85 kg/dm³ regardless of the format in which it is supplied. The weight of the coil is calculated taking into account the inside and outside diameter, as well as the material from which the strip is made. These three factors are important when calculating the total weight, but to facilitate this operation, VINCO has a weight calculator that helps you to obtain the final value without complications.
