galvanized pipe3

Hot dip galvanizing: the molten metal reacts with the iron matrix to produce an alloy layer, so as to combine the matrix and the coating. 


Galvanized pipe: It means that ordinary carbon building steel, including electro-galvanizing and hot-dip galvanizing, can effectively prevent corrosion and rust of steel after galvanizing, thereby extending the service life of steel.

Steel is galvanized steel, which is commonly used for building exterior walls such as glass curtain walls, marble curtain walls, and aluminum curtain walls as columns and stress-bearing materials, or for outdoor telecommunications towers, highways, and other open-air buildings. Galvanizing is divided into electro-galvanizing and hot-dip galvanizing.
