Golden Roofing /Corrugated 55% Galvalume Steel Coil /Metal ,AFP/
Non AFP ,G550,G450,G300
Introduction:
Galvanized steel,the cold rolled steel roll continuously immersed
in the molten zinc plating bath ,the surface fusion it a layer of
zinc anticorrosive materials in 470 dgree Centigrade heat.it is a
steel basedcomposite material ,effctively prevent the corrosion of
steel,to extend the service life,with excellent corrosion
resistance,good surface quality is conducive to deep
processing,economical and practical,widely used in
construction,household appliances,vehicles,container manufacturing
industry ,electromechanical industry etc.55% aluminum, 43.4% zinc
and 1.6% silicon at 600 C. The whole structure is composed of
aluminum, one iron, one silicon and one zinc, forming a compact
four element crystal. Heat plated aluminum, zinc and silicon (GL)
products, with various strength and thickness of the cold rolled
steel plate as the base material, on the surface of the strip, heat
plating aluminum (AL55%), zinc (ZN43.4%), silicon (S11.6%) alloy,
have excellent corrosion resistance.
