Activity Description

The production activities of the product include raw material preparation, material cutting and forming, coating preparation, cutting, packaging, and other processes.

Process Description

Aluminum-zinc coated steel sheet is a coated steel sheet obtained by hot-dip coating an Al-Zn layer on both sides of cold-rolled steel sheets of various thicknesses and strengths, with zinc and aluminum as the main components. It combines the physical protection and high durability of aluminum with the electrochemical protection characteristics of zinc.
