Aluminum zinc plating steel coil is an important alloy material which is often used in daily life.

It with many excellent characteristics: strong corrosion resistance, 3 times of pure galvanized sheet; beautiful zinc flower on the surface, which can be used as building exterior board.

Aluminum zinc alloy steel plate has good heat resistance, can withstand high temperature of more than 300 degrees Celsius, similar to the high temperature oxidation resistance of aluminum plated steel plate, it is often used in chimney tube, oven, illuminator and fluorescent lamp shade.

The thermal reflectance of Al Zn steel sheet is very high, which is twice as high as that of galvanized steel sheet.

Because the density of 55% Al Zn is smaller than that of Zn, the area of Al Zn steel sheet is more than 3% larger than that of galvanized steel sheet with the same weight and thickness of gold plating layer.

Specification

Advantages

1.Available for customized specification on customers’ request.
2.Perfect Corrosion Resistance. The service life of galvalume is 3-6times as long as that of galvanized surface.
3.Perfect Processing Performance. Fully meet the requirement of roll processing, stamping, bending, ect.

5.Perfect Heat Resistance. Galvalume products can be used at 315 degree Celsius for a long time without discoloration.
6.Excellent adhesion between the paint. Easy to paint and can be painted without pretreatment and weathering.

Galvanized Steel Coil Types

According to the processing method, we divide galvanized steel into the following categories:

1. Hot-dip Galvanized Steel Coil

As the name implies, hot-dip galvanizing is immersing the cleaned iron sheet into the molten zinc bath at about 500 degrees to form a zinc layer. It is the most commonly used method. It has some advantageous features:

1) The entire steel surface is uniformly covered with a zinc layer, even the corners, hollows, etc. so that the steel sheet is fully protected.

2) The cost of hot-dip galvanizing is cheap.

2. Electro-galvanized Steel Coil

Electro-galvanizing is a process of applying a layer of zinc to steel through electroplating, with a saline anode and steel conductor. It is able to enhance the corrosion and heat resistance of steel. Also, it makes steel sheets more good-looking.
