Product Description

Product Description

Hot-dip Zn-AL-MG alloy coated 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, Zn-AL-MG 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.
 

Product Features

1.Superior corrosion resistance: With the addition of MG and AL content, Zn-AL-MG alloy coated steel has superior corrosion resistance. The planar corrosion resistance of Zn-AL-MG coating is about 3 times that of GI coating.
2. Formability: The coefficient of friction of the Zn-AL-MG coating is 15% lower than that of the GI coating, and it remains stable during reciprocating friction, giving it excellent formability.
3. Cost Reduction: An excellent alternative to much more costly materials such as aluminum and stainless steel.
