ZAM 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. Wanzhi Group provides professional customized services for applications in construction, home appliances, automobile manufacturing, the chemical industry, etc., supplying ZAM coil, sheet, and strip materials, and deep processing such as forming, bending, punching, etc..
ZAM Steel Specification
Wanzhi Group has a galvalume and ZAM coating steel production line with an average monthly output of 10,000 tons, producing full-size alloy-coated steel with a delivery time of 5–45 days. If you are interested in coated steel, you can contact us to request a sample!

ZAM Steel Coating and Applications
ZAM 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 +6%Al+3%Mg. (Coating used by Wanzhi ZAM)
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.
ZAM Coated Steel Benefits
- Corrosion resistance: ZAM 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.
- Weathering: Keeps steel from deforming in high-temperature environments.
- Durable: Zinc-aluminum-magnesium-coated steel is harder and has good wear resistance.
- Machinability: Can be cold worked, cut, bent, stamped, and other in-depth processing.
Comparison of GI, GL ZAM Steels
GI steel, GL steel and ZAM 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, ZAM hardness is 140Hv-160Hv.
- Corrosion resistance: ZAM 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.
