What is hot dipped galvanized sheet?

Hot-dip galvanizing is a process of coating steel with a thin zinc layer, which serves as a barrier between the steel and the environment. The finish is applied by passing the steel through a molten bath of zinc at a high temperature.
The galvanized steel plate is covered with aluminum-zinc alloy on the surface of the steel plate. It is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600 ° C. Its entire structure is composed of aluminum-iron-silicon-zinc, forming a dense An alloy-coated steel sheet of quaternary crystal.

Galvanized sheet is refers to the surface has a layer of zinc plated steel plate.

Galvanized is a frequently used economic and effective anticorrosion method, about half of the zinc production in the world are used in this process.
Galvanized steel is regular steel sheets that have been coated in zinc to make them corrosion resistant. Regular steel is made of iron which will rust when exposed to moisture, either in the form of rain or ambient humidity. Over time rust will corrode a steel part to the point of failure.

Description	Galvanized steel is mild steel with a coating of zinc. The zinc protects the steel by providing cathodic protection to the exposed steel, so should the surface be damaged the zinc will corrode in preference to the steel. Zinc steel is one of the most widely used products, used extensively in the building sector, automotive, agricultural and other areas where the steel needs to be protected from corrosion
