The aluminum-magnesium-zinc steel sheet (Al-Ma-Zn) is a new type of high-corrosion-resistant coated steel sheet. Its base layer is mainly composed of zinc, plus 11% aluminum, 3% magnesium and a small amount of silicon. The surface of the aluminum-zinc-magnesium steel plate has a fine spangle crystal texture, and the surface is coated with a special resin protective film to keep the surface of the product smooth and metallic.

Excellent Performance

• Self-healing: The wound of the aluminum-magnesium-zinc steel plate is self-healing, and its cross section is usually covered by a dense protective film composed of zinc hydroxide, alkaline zinc chloride or magnesium hydroxide.

• Good corrosion resistance: It can effectively resist the corrosion of various acid and alkali chemicals and prolong the service life of steel.

• High temperature resistance: When the temperature is as high as 450℃-650℃, the coating can still be guaranteed not to fall off.
