Aluminized zinc steel plate

Because the steel plate will be affected by moisture oxidation rust, it must be added on the surface of the anti-corrosion protective layer, the general use of anti-corrosion coating is divided into hot dip galvanized Zn and hot dip aluminum zinc alloy Al-Zn (aluminum zinc alloy composition of 55% aluminum, zinc 43.5% and silicon 1.5%, referred to as 55%Al-Zn).

Differential introduction

The difference between galvanized plate and aluminized zinc plate:

The difference between galvanized plate and aluminized zinc plate mainly lies in the difference of coating, the surface of galvanized plate is evenly distributed with a layer of zinc material, which plays an anodic protection role on the base material, that is to say, the alternative corrosion of zinc material protects the use of the base material, and only when the zinc is all corroded can damage the base material inside.

The surface coating of the aluminized zinc plate is composed of 55% aluminum, 43.5% zinc and a small amount of other elements. The surface of the aluminized zinc coating is a honeycomb structure at the microscopic level, and the "honeycomb" composed of aluminum contains zinc. In this case, although the aluminized zinc coating also plays the role of anode protection, But on the one hand due to the reduction of zinc content on the one hand because the zinc material is not easy to electrolyze by aluminum, the role of anode protection is greatly reduced, so once the aluminum plated zinc plate is cut, the edge of the cut is basically lost in the case of protection will soon rust, so the aluminum plated zinc plate should be cut as little as possible, once the cut after the application of anti-rust paint or zinc-rich paint to protect the edge, Only then can the service life of the plate be extended.
