Zn-Al-Mg steel coil

Zinc aluminum magnesium coated steel plate refers to a coated steel plate with a certain amount of Al and Mg added to the hot-dip galvanized coating or a certain amount of Mg element added to the hot-dip aluminum zinc coating, which has the characteristics of high corrosion resistance and high edge protection.

Corrosion resistance is 3-10 times higher than hot-dip galvanizing, the incision self repairs, the processing weldability is good, the thin coating reduces costs, and it is adaptable to multiple scenarios

Zinc aluminum magnesium is usually divided into three categories based on the aluminum content in the coating: low aluminum products (aluminum content less than 5%), medium aluminum products (aluminum content 5-13%), and high aluminum products (aluminum content 45-70%).

Product Name	W(AL/%)	W(mg/%)	Corrosion resistance of edge banding plate with the same thickness coating (1-5 from strong to weak)	Corrosion resistance of the edge of the same thickness coating (1-5 from strong to weak)	Main purpose of the product
High alumina zinc aluminum magnesium	53%	1.6-2.0%	1	3	Building material sheets, walls and roofs
Aluminum Zinc Aluminum Magnesium 1	6%	1.2-3.0%	4	2	Solar photovoltaic bracket, keel
Aluminum Zinc Aluminum Magnesium 2	11%	1.2-3.0%	3	1 (Especially in animal husbandry)	Solar photovoltaic brackets, keels, and animal husbandry walls and roofs
Low aluminum zinc aluminum magnesium	2.5%	1.5%	5	4	Home appliances and automobiles
