Zn-AL-MG alloy coated steel, also known as ZAM 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, ZAM 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.

Advantage of Zinc Aluminum Magnesium coated steel
* Zn Al Mg coating steel is 5~8 times the corrosion resistance of the flat part of the galvanized steel plate.
* The unique cut-off coating self-healing anti-corrosion performance.
* Ihe excellent acid and alkali corrosion resistance, and can replace stainless steel in some fields.
* The better abrasive resistance than GI and GL.
* Machinability stability under severe conditions, can replace the hot-dip galvanized plate.
* Environmentally and friendly products. It doesn't contain heavy metal ions. Meet ROHS standards
Zn Al Mg coating steel has better anti-corrosion performance than GI and GL. The ability of cutting port protection is good. Its welding performance is also deserved to be mentioned. It could be even a good replace for stainless steel from some parts.
