What kind of plate is galvanized aluminum magnesium plate?
Galvanized aluminum-magnesium plate is an alloy-coated plate in steel-plated products. The mass fraction of metal elements in the coating is: aluminum 53%, zinc 43%, magnesium 2%, 1.5% silicon and other elements. The surface of aluminum-zinc-magnesium plated steel plate has fine zinc flower texture formed by crystallization, and the neat fine zinc flower makes the appearance of the plated product more natural and delicate.

Al-Zn-Mg coating has corrosion resistance, and all metal elements in the alloy coating work together, which reduces the consumption speed of the coating on the surface of the plated steel, and at the same time, the corrosion resistance of the cut section of the plated steel is also improved. In most cases, its performance is better than that of aluminum-zinc coated steel plate with the same coating amount, and also better than that of galvanized steel plate.

In the aluminum-zinc-magnesium electroplating steel plate with activation technology, zinc in the alloy coating provides sacrificial protection and aluminum provides passivation protection. The addition of magnesium activates the alloy coating, and the coordination of zinc and aluminum reduces the consumption rate of the coating, forming an insulating protective layer on the incision and section. The inside of the coating provides barrier protection, which greatly improves the corrosion resistance of coated steel.

Aluminum-zinc-magnesium plated steel plates can be directly used as finished products, and can also be used as the base material of color-coated plates. It can be mainly used as the wall material of steel structure building envelope system, and its final application fields include roofs, walls, ceilings, rolling doors, etc. of industrial workshops, power plants, stadiums, airports, exhibition halls or civil houses. At the same time, its excellent formability and ductility can also be applied to manufacturing industries, such as pipes, furniture, electrical backplanes, automobile parts and so on.
