ZAM steel refers to zinc aluminum magnesium steel, and its coating consists of Zn, Al, and Mg. Adding Al and Mg contents offers much better corrosion resistance, several times to ten times higher than that of GI and GL steel. In addition, zinc magnesium aluminum coating has excellent processing performance and great hardness. And it also has a great self-healing effect on the cutting area. Because of its superior corrosion resistance, ZAM steel products are widely used in construction (roofing and wall), steel structures and accessories, railways, bridges, agriculture and animal husbandry (greenhouses, livestock farms, etc.), home appliances, automobiles, color-coated substrates, etc.
