1. What is the zinc-aluminum-magnesium coating?

According to the definition of European standard EN10346-2015, zinc-aluminum-magnesium coating is a ternary alloy coating whose main component is zinc, and the content of aluminum and magnesium is between 1.5% and 8% (the magnesium content is not less than 0.2%).

European standard EN10346-2015 Zinc-Aluminum-Magnesium Coil is a new type of lightweight and high-strength product with zinc-aluminum-magnesium coating. It is used in construction, automobile manufacturing, power industry, photovoltaic and other fields. Progress and production costs have decreased, and its fields of application have continued to expand.

2. What should be paid attention to when purchasing zinc-aluminum-magnesium coils?

High-quality zinc-aluminum-magnesium coils should have uniform composition and dense structure to ensure excellent corrosion resistance and mechanical properties, thereby ensuring the service life and performance stability of the product. For example, the zinc-aluminum-magnesium coil material used in the building materials scene must have more than 3% magnesium, so as to ensure 30-year corrosion resistance in the atmospheric environment.

Commonly used zinc-aluminum-magnesium materials are: DX51D, S350GD, S420GD, S450GD, S550GD, etc. Generally speaking, the material of zinc-aluminum-magnesium coils can be found by checking the product quality inspection report or communicating with the supplier. However, whether the chemical composition of the material meets the relevant standards and requirements is the main basis for ensuring that the material has the required mechanical properties and corrosion resistance.
