1. galvalume steel sheet is designed to extend the service life of the steel sheet by covering its surface with a layer of zinc and aluminum to prevent corrosion. This thin steel sheet that has been galvalume is called galvalume steel sheet.
The key to the production of galvalume steel sheet lies in the zinc-aluminum coating on its surface. This process effectively prevents the oxidation of the steel surface. Galvalumed steel sheet usually has the characteristics of small zinc flowers, and its surface presents a white tone.

2. Stainless steel is known for its excellent corrosion resistance and can resist erosion by air, steam, water and various chemically corrosive media. The production of stainless steel depends on other metal elements added to the steel. Through the changes in the internal structure of these elements, the product has excellent rust resistance. For example, chromium stainless steel, chromium-nickel stainless steel, and chromium-manganese-nitrogen stainless steel are all common types of stainless steel. The surface of stainless steel is relatively smooth, without any decorations, showing its unique metallic texture.
