Aluminum-Magnesium-Zinc coated steel 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-5% aluminium alloy steel sheet, it has less adhesion but equal corrosion resistance. In addition, it can be used instead of stainless steel or aluminium sheet because of its excellent red rust resistance.

Use cases of zinc aluminum magnesium steel
Zinc Aluminum Magnesium Alloy Coated Sheet is frequently used in the metal forming industries of construction, road protection, three-dimensional parking lots, storage equipment, and automobile electromechanical devices.
All types of steel components, corrosion-resistant parts, keel ceilings, perforated plates, and cable trays may be produced using it. By switching to zinc aluminum magnesium coil, post-galvanizing and post-painting processes that are required for some applications can be skipped, lowering costs and shortening lead times.
The Zn -Al-Mg Coated Coil's and its color steel's corrosion resistance is five times greater than that of conventional Galvalume Steel, which addresses the issue of color steel's rapid rusting in coastal areas as well as its short service life in applications such as structure engineering, power engineering, purification engineering, photovoltaic design, etc.
Products made of steel that has been coated with zinc, aluminum, and magnesium are widely used, particularly in civil construction such as keel ceilings, perforated plates, and cable bridges, especially in the agricultural sector in infrastructures such as breeding greenhouses, steel structures, steel components, greenhouses, breeding equipment, railways, roads, and many more.
