What Is Zam?
Zn-Al-Mg is a new type of highly corrosion-resistant coated steel sheet with a coating composition consisting of zinc as the main substrate in combination with aluminum (about 11%), magnesium (about 3%) and a trace amount of silicon.Adding Al, Mg, and Si to it, the composite effect of these added elements improves corrosion resistance.Compared with hot-dip galvanized steel sheet and hot-dip galvanized-55% aluminium alloy steel sheet, it has less adhesion but equal corrosion resistance.
Features Of Hot Dip Zn-Al-Mg Alloy Coated Steel
· Longer service life than other coated products
· Cut edge rust protection - the hallmark feature of ZAM
· Thinner coating yet more protection - ecologically friendly
· Excellent in severe environments - especially coastal and agricultural
· Eliminates the need for post dip (batch) galvanizing
· Superior formability due to coating characteristics
· Cost savings through longer service life and reduced maintenance
· Bridges the product gap between heavily coated galvanized and costly stainless steel
