Specification and thickness of galvanized sheet

The thickness of ordinary galvanized sheet is 0.4~2.0.

Generally, it is not produced by large steel mills of state-owned enterprises, but by small steel mills of private enterprises. Conventional specifications are 0.35, 0.30, 0.28, 0.25, the thinest is generally 0.1, more than 2.0mm, because straightening is very difficult, the price above 2.0 will increase with the increase of thickness.

There are two kinds of galvanized sheet: hot galvanized sheet and electrogalvanized sheet. The national standards of these two kinds of galvanized sheets are briefly introduced.

According to GB/T 2518-2008, the thickness range of hot galvanized sheet is 0.3 ~ 5.0 mm

According to GB/T 15675-2008 "Continuous electric galvanized, zinc-nickel alloy coated steel plate and steel strip", its plate thickness is not specified. But according to GB/T 708-2006 "cold rolled steel plate and strip size, shape, weight and allowable deviation", galvanized sheet thickness is 0.40 ~ 4.00 mm
