AS1397 G550/SGC570 55% Alu-zinc Steel Slit Coils Galvalume Strip Steel AZ150 Anti Finger Print Unoiled

Introduction of Galvalume / Aluzinc Steel Coil and Slitted Strip Coils

The surface of the Galvalume / Aluzinc steel sheet presents a unique smooth, flat, and gorgeous spangle looking, with a silver white base color. The special coating structure gives it excellent corrosion resistance. The normal service life of Galvalume / Aluzinc Steel Sheet and Coils can reach 25 years, and they have good heat resistance and can be used in high-temperature environments at 315 ℃; The adhesion between the coating and the paint film is good, and it has good processing performance, which can be used for stamping, shearing, welding, etc; The surface conductivity is very good.

The coating consists of 55% aluminum, 43.5% zinc, and 1.5% silicon in weight ratio, respectively. The production process of aluminum zinc steel sheet is similar to that of galvanized steel plate and aluminum plated plate, and it is a continuous melting coating process. 55% aluminum zinc alloy coated aluminum zinc steel plate has superior corrosion resistance compared to galvanized steel plate of the same thickness when exposed to the same environment on both sides. 55% aluminum zinc alloy coated aluminum zinc steel ( 55% Alu-zinc Steel) plate not only has good corrosion resistance, but also color coated products have excellent adhesion and flexibility.

Application of Galvalume / Aluzinc Steel Coils 

• Buildings: roofs, walls, garages, soundproof walls, pipes, and modular houses, etc

• Automobile: muffler, exhaust pipe, wiper accessories, fuel tank, truck box, etc

• Home appliances: refrigerator backplate, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof strip, LED backlight, electrical cabinet, etc

• Agriculture: pig houses, chicken houses, granaries, greenhouse pipes, etc

• Others: heat insulation cover, heat exchanger, dryer, water heater, etc.

Substrate Material

There are two types of galvanised steel sheets, one for forming and the other for structural use.

(1) For forming

In general, the international common specifications for galvanised steel sheet for forming are divided into the following categories, and the appropriate grade can be selected according to the degree of forming and processing. (Take Baosteel as an example)

(2) Structural use

General international specifications for structural galvanised steel sheets are divided into the following categories based on the performance parameters of the substrate, and the strength level can be selected according to the needs of the application and thickness. (Take Baosteel as an example)

DECHO building colour steel plate can meet the need to use colour steel plate as raw material for building. Decho Building Materials colour steel plate is mainly processed into, for example, colour steel corrugated board or colour steel composite sandwich board after our colour steel plate is widely used in the construction of airports, freezers, steel plants, warehouses, and other industrial buildings and commercial buildings, such as the roof of the colour steel tiles, colour steel plate sandwich walls and doors.

Reasons for choosing Decho Building Materials new material:

1. Provide extremely rich colour choices
