The steel can be coated with differing thicknesses of tin, and even different thicknesses on the two faces (differential coatings) may be produced to cater for varying conditions at the internal and external surfaces of a container.

16 Οκτ 2014 · In practice the range of steel base thickness is from 0.13 mm to 0.50 mm and the tin coating from 0.5 g/m2 to 15.2 g/m2 tin per surface. There are international and national standards which specify the ranges and tolerances for the various characteristics, and methods of verifying them.
Tata Steel’s range of products includes; tinplate, tin-free steels (ECCS), blackplate, and our market leading Protact®laminated steel. This includes; clean steels for D&I, high strength formable steels for easy-open-ends and coated steels ideally suited to coil-fed canmaking operations. Our manufacturing base produces reliable

INTRODUCTION. This specification is the metric counterpart of Specification A 623. It is not intended to replace A 623. Users of the standard should note several very significant differences in how the product is produced and marketed. (1) The metric product does not carry the overrun associated with tin mill products produced to customary units.
Steels for packaging are thin gauge flat carbon steels, tin or chromium coated on both sides. This particular combination gives the tinplate an interesting set of properties: strength and stiffness, formability, weld-ing ability, lacquer ability and printability, good cosmetic appearance and corrosion resistance.
