Product Description

Z-A-M steel has excellent corrosion resistance, heat resistance, and machinability. It is a highly corrosion-resistant metal-coated steel. At the same time, the alloy layer composed of zinc, aluminum, magnesium, and silicon can improve the steel's scratch and chemical resistance. MESCO STEEL Group provides professional customized services for applications in construction, home appliances, automobile manufacturing, the chemical industry, etc., supplying Z-A-M coil, sheet, and strip materials, and deep processing such as forming, bending, punching, etc..

Z A M Steel Coating and Applications

Z A M steel is a high-strength steel substrate coated with an alloy layer of three metals, Zn, Al, and Mg. Zn improves the corrosion resistance of the steel, Al provides weathering and oxidation resistance, and Mg enhances the corrosion resistance of the steel. The higher the aluminum and magnesium content, the better the corrosion resistance.

Common Coating Types

• Zn +1.5%Al+1.5%Mg.
• Zn +2%Al+2%Mg.
• Zn +11%Al+3%Mg. (Coating used by Wanzhi Z A M)

Application

• Automobile exterior panels, home appliance exterior panels, etc.
• Color-coated substrates, interior panels for home appliances, etc.
• Soundproof board, photovoltaic support, outdoor screen/fence, etc.

Z A M Coated Steel Benefits

• Corrosion resistance: Z A M coating can make the steel in the humidity, salt spray, and other environments to maintain the performance of stability, and can resist the erosion of harsh weather conditions.
• Self-repairing properties: Z A M-coated steel maintains high corrosion resistance even in scratched or damaged areas.
• Weathering: Keeps steel from deforming in high-temperature environments.
• Durable: Zinc-aluminum-magnesium-coated steel is harder and has good wear resistance.
• Machinability: It can be cold-worked, cut, bent, stamped, and used for other in-depth processing.

 

Comparison of GI, GL Z A M Steels

GI steel, GL steel, and Z AM steel are three common metal-coated steels and Wanzhi Group's popular coated steel materials, which are widely used in construction, industry, transportation, and other fields. However, the coating compositions of these three materials are different, so there are differences in price, performance, and application.

 

 

• Cost: galvanized has the lowest processing cost, galvalume has a relatively high cost, and Zinc-Aluminum-Magnesium has the highest cost.
• Hardness: GI hardness is 55Hv-65Hv, GL hardness is 100Hv-110Hv, and Z AM hardness is 140Hv-160Hv.
• Corrosion resistance: Z AM is more corrosion resistant than GL and GI steel.
• Uses: galvanized steel is mainly used in general indoor and outdoor environments, Galvalume steel is suitable for use in humid and high-temperature environments, and Zinc-Aluminum-Magnesium steel is suitable for use in marine and chemical environments.

ZInc Aluminium Magnesium Alloy Coated Steel Coil

Zinc Aluminum Magnesium coating is through the role of aluminum and magnesium, so that hot dip plating layer has excellent ANTI-corrosion resistance, wear resistance and machinability, can be widely used in various fields,especially for photovoltaic bracket and husbandry. Zn-al-mg-coated steel plate allows customers using GI products to directly replace ZN-AL-MG-coated coating steel plate without changing the existing processing, assembly, painting and other processes.
