Product Description

Galvanized Steel Pipe Square ASTM A252-1998 Q195 Q235 Q345 25*25mm For Structural

Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized steel pipe base and hot-dip galvanized steel pipe undergo complex physical and chemical anti-galvanizing to form a zinc-iron alloy layer with a tight corrosion-resistant structure.
The alloy layer is formed by combining the pure zinc layer and the steel pipe matrix. Hot dip galvanizing is one of the most excellent electroplating methods for protecting steel substrates. It is the liquid state of zinc. After quite complex physical and chemical action, not only a thick pure zinc layer is plated on the steel, but also a zinc-iron alloy layer is formed. This method not only has the corrosion resistance of galvanizing, but also has strong corrosion resistance unmatched by galvanized due to the zinc-iron alloy layer.
