Hot dipped galvalume steel coil
Hot dipped galvalume steel sheet(coil) is a formed by passing the full hard sheet which has undergone the acid washing process and rolling process through the aluminum and zinc alloy pot. The aluminum-zinc alloy coating with reasonable ratio; aluminum weight ratio is 55%, zinc weight ratio weight ratio is 43.4%
Application
Indoor and outdoor decoration, electrical, electronics, auto parts and pipes and so on.
Product features.
Corrosion resistance: Hot dipped galvalume steel shows superior anti-corrosion quality than galvanized steel in the temperature and salt spray test.
Processing: Processibility of galvalume steel sheet is same as galvanized steel sheet and, especially the crack of forming place is less than galvanized steel sheet.
Weldability: Has excellent weldability.
Paintability: When for signs and commercial use, can be painted without pretreatment and weathering, while galvanized steel sheet need such treatment.
