产品简介

Al Zn Mg Steel Plate (band)

 Zinc-aluminum-magnesium is a kind of alloy metal, mainly used for surface anti-corrosion treatment of steel and steel products, including various zinc series coatings and a large number of whole steel parts immersion-plated anti-corrosion; initially used as surface anti-corrosion of steel products The metal processed is pure zinc. With the improvement of technology, alloy metals such as aluminum-zinc alloy and zinc-aluminum-magnesium alloy have appeared one after another, which increases the corrosion resistance of the metal layer.
       Huajing super corrosion-resistant zinc-aluminum-magnesium alloy coated steel sheet (strip) is formed by high temperature solidification of zinc (Zn), aluminum (Al), magnesium (Mg) and other rare elements on the surface of the steel plate (strip) using special advanced technology. Eutectic structures such as Zn, Al, Zn2Mg, etc., penetrate the steel base and form a firm bonding surface with the steel base, which prevents corrosion of the steel strip; the surface of the zinc (Zn)-based coating containing magnesium (Mg) will form dense protection Layer, and play the role of anti-corrosion and self-repairing of steel belt.

Product Performance: Super corrosion resistant

The samples of Wuxi City Product Quality Supervision and Inspection Institute conducted salt spray test. The galvanized steel strip showed red rust after 384 hours, while the super corrosion-resistant zinc-aluminum-magnesium alloy coated steel strip did not see red rust after 1000 hours. Compared with ordinary galvanized products, it can achieve better corrosion resistance, which is 3 to 5 times that of hot-dip galvanized steel.
100g, 275g ultra-corrosion-resistant zinc-aluminum-magnesium alloy coated steel strip has no red rust on the surface for 1000h
Red rust on the surface of 275g galvanized steel strip 384h

Super corrosion resistance: Salt spray test

02

Product performance: Self-healing

The coating components around the cutting surface and the punching surface can automatically dissolve out and form a dense protective film to cover the cut end surface, incision and embroidered parts, realizing automatic repair of the alloy coating.

The coating components automatically dissolve and form a dense protective film to continuously cover the end surface or cut
Form a dense protective film to completely cover the end face or cut and red rust parts

Self-healing function: cut or end face

03

Product performance: Long life

Since the super corrosion resistance is 5-10 times that of ordinary hot-dip galvanized sheets and the corrosion-resistant self-repairing function of the cut section, the components made of hot-dip galvanized aluminum-magnesium steel alloy coated sheets have a long service life. Under normal circumstances, it can Reach 50-100.

Product performance: Zinc-free

The ultra-corrosion-resistant zinc-aluminum-magnesium alloy coated steel plate (strip) has no spangles, and the surface coating is dense and flat, which is beneficial for subsequent personalized processing and advanced coating after the plate (strip) is formed.
The welding process is resistance lap welding, and the weld quality is good

Zinc-free--easy welding process

04

Product performance: Strong attachment

The coating of hot-dip galvanized aluminum-magnesium steel is denser than that of galvanized steel, so it is not easy to peel off the coating during the stamping process. It has excellent tensile, stamping, bending, welding and other processing properties under severe conditions, and due to the coating The hardness is high, so it has excellent damage resistance.
180° bending test: no coating peeling off on the curved outer surface
Complicated bending test: the steel plate has good bending performance and good coating

  • Strong attachment:Bending test

  • Strong attachment:Complex bending test

05

Product performance: Safety and environmental protection

This product adopts the ecological water washing method to remove rust, and realizes the green and safe environmental protection production process. The product coating does not contain heavy metal elements such as lead, which realizes the safety and environmental protection of the product application field.
