Galvanized Steel Plate
Hot-Dip Galvanized Steel Sheet
Galvanized sheet is a type of anti-corrosion steel with a surface treated by galvanization. It is divided into two major categories: hot-dip galvanized sheet (GI) and electro-galvanized sheet (EG). Common grades include DX51D+Z, SGCC, SGCD, ST01Z, ST02Z, etc. The specifications cover galvanized coil sheets and galvanized plates with thickness ranging from 0.3mm to 3.0mm and width ranging from 600mm to 1500mm.

You can be assured that all the products you get from us are reliable.
Hot-Dip Galvanized Steel Sheet is a steel product manufactured by immersing steel sheets—after cleaning and annealing—into molten zinc baths for coating treatment. This process forms a uniform, dense zinc-iron alloy coating on the steel surface.
