MESCO Group has a galvalume and Z A M 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!
MESCO is a coated steel manufacturer, supplying steel raw materials and finished products to various industries, our main coated products include GI, PPGI, GL, PPGL, tin, aluminum, chrome, organically, pvc, Z A M, zinc phosphate steel, etc. all kinds of metal roofing plates, stainless steel plates, etc. We have exported metal coating steel and organic-coating steel to the UAE, Saudi Arabia, Malaysia, Singapore, Chile, Colombia, Libya, Azerbaijan, Spain and 200 other countries.
| Feature | Z-A-M Steel | Galvalume Steel |
|---|---|---|
| Composition | Zinc, Aluminum, and Magnesium | 55% aluminum, 43.4% zinc, and 1.6% silicon |
| Corrosion Resistance | Superior due to the inclusion of magnesium | Very good, but slightly less than Z AM |
| Coating Thickness | Typically thinner due to higher efficiency | Generally thicker for similar performance |
| Durability | High, with excellent edge protection | High, but edges may be more susceptible to corrosion |
| Surface Appearance | Smooth and shiny | Smooth and slightly spangled |
| Cost | Generally higher due to advanced properties | Generally lower compared to Z AM |
| Applications | Roofing, siding, automotive, appliances | Roofing, siding, construction |
| Environmental Impact | Uses less zinc, potentially more eco-friendly | Standard zinc-aluminum coating |
| Paint Adhesion | Excellent | Very good |
| Heat Resistance | Good | Good |
Both materials offer excellent performance in terms of durability and corrosion resistance, but Z AM steel tends to provide enhanced protection, especially at the edges, due to its unique composition. Galvalume steel, on the other hand, is widely used and cost-effective, making it a popular choice for many applications.
EN 10346: Specifies the technical delivery conditions for continuously hot-dip coated steel flat products, including zinc-aluminum-magnesium coatings.
JIS G 3323: Specifies the requirements for hot-dip zinc-aluminum-magnesium alloy-coated steel sheets and coils.
ASTM A1046/A1046M: This specification covers the requirements for steel sheet, zinc-aluminum-magnesium alloy-coated by the hot-dip process.
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.
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.
