Cold Rolled Zinc coated DX51D AZ150 AL-ZN Hot Dipped Galvanized Coil Zero Spangle Gi Sheet

Hot dipped galvanized steel sheet & coil is made of carbon steel coated in zinc utilizing the hot-dip process. The end result of this process is a layer of zinc on each side of the steel sheet or coil that is tightly adhered to the steel through the formation of an iron-zinc alloy bonding layer.

Is galvanized better than carbon steel?

Galvanized steel is created by dipping standard steel into molten zinc by a process called hot dipping. The layer of zinc serves as a protectant from corrosion. The protectant makes galvanized steel the best option, over untreated carbon steel, for worksites that are exposed to acid rain, road salt, and sea water.

Hot dip galvanized steel plate DC51D,also named as hot dip galvanized steel sheet DC51D+Z and hot dip zinc coated steel plate and coil DC51D+ZF.Under Q/BQB 420 steel standard,there are DC51D+Z,DC51D+ZF which is for bending and profiling quality,DC52D+Z,DC52+ZF which is for drawing quality,DC53+Z,DC53+ZF which is for deep drawing quality,DC54D+Z,DC54D+ZF which is for special deep drawing quality,DC56D+Z,DC56D+ZF which is for extra deep drawing quality.

DX51D stands for galvanized steel sheet. The first D means flat steel for cold forming. The X means the rolling state is indefinite. 51 is the series number of the steel. The second D means hot dipped galvanized.

Galvanized steel coil is the steel coil with hot dipped surface coating such as zinc. According to steel material’s advantages of strength, durability and toughness, also according to advantage of protection as zinc plating against to rust and corrosion, galvanized steel coils widely are applied to more industries.
