The hot-dipped galvanizing refers to the metal surface treatment. The metal product will be immersed it in the bath of the molten zinc. The whole process of the hot-dipped galvanizing process can be divided into 3 parts, like the surface preparation, galvanizing, and inspection.

Perforated steel sheet is often galvanized for increased corrosion resistance. Galvanizing is a process that involves coating the steel sheet with a thin layer of zinc. The zinc acts as a barrier, protecting the steel from corrosion and oxidation. The added corrosion resistance makes galvanized perforated steel sheets an ideal choice for outdoor applications, such as stair treads, fence panels, and protective grates.
