Galvanized coil is a surface galvanized sheet with yield strength of 235MPa.

Galvanized coil, a thin steel sheet that is dipped into a molten zinc bath to adhere a layer of zinc to its surface. It is mainly produced by the continuous galvanizing process, in which rolls of steel sheet are continuously dipped into a bath of molten zinc to make galvanized steel sheet; alloyed galvanized steel sheet. This steel sheet is also manufactured by the hot dipping method, but immediately after leaving the bath, it is heated to about 500°C to produce an alloyed coating of zinc and iron. This type of galvanized coil has good paint adhesion and weldability.

Warehouse Storage

Galvanized steel is represented by cold-rolled and hot-rolled coils coated with zinc, which helps protect the steel from atmospheric corrosion. Galvanized steel coils are successfully used in industries with strict requirements on corrosion resistance, durability, strength and appearance,and can form or apply a variety of coatings. Galvanized steel coils can be customized according to their own needs.

What are advantages of galvanized steel?

Because it is produced through applying Zn coat on both faces by hot dip process. It enjoys both the physical protective feature and the electrochemical protective property of Zn.

>>Machinability: It can satisfy the processing requirements of rolling, coiling and others processes alike.

>>Thermal resistance: Common HDG steel plate normally works under 230℃, and has its color changed at 250℃, however, Galvanized steel plate can sustain the environment at 315℃ for long time.

>>High reflectivity: Reflection ability of heat and light is twice as much as those of hot-dip zinc steel sheet, and its reflectivity is more than 0.70, which is an ideal construction materials of saving energy.
