The three important elements of galvalume steel sheet are zinc, aluminium and aluminum-zinc alloy material.
Zinc is generally expressed in Z, and is the abbreviation of Zinc. In the specification, there always appears Z80, it refers to the surface galvanized content is 80 grams per square. The galvalume steel sheet is alloy steel sheet. And the aluminum and zinc components accounted for aluminium 55%, zinc 43.5% and silicon 1.5% in the galvalume compound.
The AZ100 in the specification of galvalume steel sheet means the galvalume is 100 grams per square, and AZ70 means galvalume is 70 grams per square. The texture of galvalume steel coil in the market generally have: AZ50、AZ70、AZ100、AZ150、AZ180、AZ200.
In CAMELSTEEL, our regular galvalume layer is AZ40-AZ150. In addition, the galvalume steel sheet with AZ180 and AZ200 are lesser in market, and the highest galvalume technology in domestic generally can achieve 200 grams per square.
