Top 3 Z-A-M steel manufacturer in China
First manufacturer that make Z-A-M coating mass to 450g/m2
Overall Z-A-M steel daily stock 7000-12000 tons, fast deliveryFEATURES OF HOT DIP ZN-AL-MG ALLOY COATED STEEL
1Superior corrosion resistance:
With the addition of MG and AL content, ZM alloy coated steel has superior corrosion resistance. The planar corrosion resistance of ZM coating is about 3 times that of GI coating.
2Formability:
The coefficient of friction of the ZM coating is 15% lower than that of the GI coating, and it remains stable during reciprocating friction, giving it excellent formability.
Hot-dip Zn-AL-MG alloy coated steel, also known as Z-A-M steel, is a new type of coating product. The zinc-aluminium-magnesium coating is a ternary alloy coating with zinc as the main component, and the content of aluminium and magnesium is between 1.5-8% (among which the magnesium content is not less than 0.2%). The magnesium in the coating is beneficial to promoting the formation of a very stable and well-organized and meticulous protective film, namely Hydrozincite ((Zn5 (OH)8Cl2 H2O), which generates and maintains a film-like covering on the surface of the coating, thereby ensuring excellent corrosion resistance. Compared with traditional coatings such as GI and Aluzinc, ZM alloy-coated steel is known for its superior corrosion resistance, formality, wear and scratch resistance and can be applied in a wide range of fields such as automotive, HAVC, solar photovoltaics, agriculture, high-speed guardrails, electrical cabinets, greenhouse structures, etc.
