Key Specifications/Special Features:
Galvalume coil introduce：
Materials and manufacturing process of galvanized coils
Galvalume coil is a kind of cold-rolled steel plate or hot-rolled steel plate. After degreasing, pickling, dissolving zinc, drying, etc., it is then coated with an aluminum-zinc alloy layer and a modified epoxy or polyester coating layer. Composite materials made by technology. The common aluminum-zinc alloy layer refers to an aluminum-zinc alloy layer composed of 55% aluminum, 43.5% zinc and 1.5% silicon. There are also alloy layers with other proportions.
Characteristics of galvanized coils：
1. Good corrosion resistance: The aluminum-zinc alloy layer can effectively resist corrosion of steel, thereby extending the service life of steel.
2. Beautiful: The surface of galvanized coils can be painted in various colors, which increases the aesthetics of the steel.
3. Good plasticity: Galvalume coils have excellent plasticity and can meet the needs of various complex shapes and bending processes.
4. Simple manufacturing process: Compared with other anti-corrosion materials, the manufacturing process of galvanized coils is simpler and has a wider range of uses.
Galvanizing technology：
It is mainly produced by continuous galvanizing process, made by hot dip method, but after the groove, it is heated to about 500℃ immediately to make it produce the alloy coating of zinc and iron.
Aluminum zinc coating (AZ)：
The coating design of the product is delivered with standard crystals. Ordinary crystals are the metallic luster version, and the growth of aluminum-zinc crystals is not affected under normal solidification conditions.

Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel,aluminized zinc steel(aluzinc steel),SGLC,The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at 600 ~C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a compact quaternary crystal alloy.The surface of the galvalume steel sheet is characterized by smooth, flat and gorgeous stars, and its base color is silver white. The special coating structure makes it have excellent corrosion resistance.

Product characteristics
DX51D+AZ Galvalume Steel Sheet Features
1. Thermal reflectivity.
The heat reflectivity of galvanized steel sheet is very high, twice that of galvanized steel sheet. People often use it as heat insulation material.
2. Heat Resistance.
Aluminum-zinc alloy steel sheet has good heat resistance and can withstand high temperatures above 300 degrees Celsius. It is very similar to the high temperature oxidation resistance of aluminum-plated steel sheet. It is commonly used for chimney pipes, ovens, lamps and fluorescent light covers. Corrosion Resistance.
The corrosion resistance of galvanized steel coil is mainly due to aluminum and its protective features. As the zinc wears away, the aluminum forms a dense layer of aluminum oxide, preventing the corrosion-resistant material from further corroding the interior.
3.Economy.
Since the density of 55% AL-Zn is lower than that of Zn, the area of galvanized steel sheet is more than 3% larger than that of gold-plated steel sheet of the same weight and thickness.
4. Easy to color
Excellent adhesion between Al-Zn sheet and paint, paint can be painted without pretreatment and weatherproof.
The coating adhesion of the gold-plated layer of aluminum-zinc steel sheet is better, so it can also be painted directly on billboards and general boards without pretreatment such as weathering.
5. The surface of galvanized steel sheet is gorgeous silver white.
6. Galvanized steel sheet has similar processing and coating properties as galvanized steel sheet.
