Aluminized steel sheets, also known as aluminized iron sheets or hot-dipped aluminized iron sheets. Aluminized steel sheets are made of an aluminum-zinc alloy structure, which consists of 55% aluminum, 43% zinc, and 2% silicon solidified at 600℃.

Aluminized steel sheet has good heat resistance, heat reflection, and corrosion resistance, and their mechanical and physical properties are better than cold rolled steel plate. Due to the superior performance of aluminized steel sheet, it has been widely used in our daily products. Such as automobile mufflers, household appliances, etc.

The surface of aluminized steel sheet has a characteristic smooth, flat, and gorgeous star pattern, and the base color is silvery white. The special plating structure makes it excellent corrosion resistance. The normal service life of zinc aluminized sheet is up to 25 years, and the heat resistance is very good, and it can be used in a high-temperature environment of 315℃; the adhesion between the plating and the paint film is good, and it has good processing performance, and it can be stamping, shearing, welding, etc.; the surface conductivity is very good.

Applications of aluminized steel sheet:

Construction: roofs, walls, garages, soundproof walls, pipes and modular houses, etc.

Automobile: muffler, exhaust pipe, wiper attachment, fuel tank, truck box, etc.

Home appliances: refrigerator backsheet, gas stove, air conditioner, electronic microwave oven, LCD bezel, CRT explosion-proof belt, LED backlight, electrical cabinet, etc.

Agriculture: Pig house, chicken house, granary, the pipeline for a greenhouse, etc.

Others: heat break insulation cover, heat exchanger, dryer, water warmer, etc.

 

Galvanized iron sheets are coated with a layer of metallic zinc to prevent corrosion on the surface of the steel sheet and to extend its service life. galvanized iron sheets are mainly used in construction, light industry, automotive, agriculture and fishery, and commercial industries. In the construction industry, galvanized iron sheets are mainly used in the manufacture of corrosion-resistant industrial and civil building roof panels and roof grilles; in the light industry, galvanized iron sheets are used in the manufacture of appliance housings, civil chimneys, and kitchen appliances; in the automotive industry, galvanized iron sheets are mainly used in the manufacture of corrosion-resistant parts of cars; in the agriculture and fishery industry, galvanized iron sheets are mainly used in the storage and transportation of grain and the freezing and processing of meat and aquatic products; in the commercial industry, galvanized iron sheets are mainly used in the storage and transportation of materials and packaging appliances.

galvanized iron sheets and aluminized zinc sheet which is good

In terms of the production process, galvanized iron sheets are a little more difficult. Galvanized iron sheets can form electrode protection, and corrosion resistance can be effectively improved. As for the cost performance, you cannot simply say which one is better, but it depends on which one can meet your needs and which one you choose. If galvanized iron sheets are enough to meet your needs, there is no need to spend more money on zinc aluminized sheets.
