l The concept of galvanized steel sheet
Galvanized steel is widely used in building materials, home appliances, automobiles, the environment, machinery, ships and many other areas of an alloy coated steel. The aluminum-zinc-plated steel plate is composed of 55% aluminum, 43.4% zinc and 1.6% silicon at the high temperature of 600 ℃, and the whole structure is composed of aluminum-iron-silicon-zinc to form dense An alloy plated steel plate of quaternary crystal。

l Characteristics of galvanized steel sheet
The galvanized steel sheet has many excellent characteristics:

Corrosion resistance: "galvanized steel coil" of the corrosion resistance is mainly due to aluminum, aluminum protection. When the zinc is worn, the aluminum will form a layer of dense alumina, to prevent further corrosion of corrosion-resistant material inside。

Heat resistance: Al-Zn alloy steel plate has good heat resistance, can withstand more than 300 degrees Celsius temperature, and the aluminum plate is very similar to high temperature oxidation resistance, often used in chimney tubes, ovens, lanterns and lighting。

Thermal reflectivity: Al-Zn-plated steel sheet has a high heat reflectivity, twice that of galvanized steel, and is often used as a heat-insulating material。

Economy: Because the density of 55% AL-Zn is smaller than the density of Zn, the area of the galvanized steel sheet is larger than that of the galvanized steel sheet by 3% or more in the case of the same weight and the same thickness of the gold plating layer。

l The Application of Aluminized
Buildings: Roofs, garages, walls, pipes and modular houses
Automotive: muffler, exhaust pipe, wiper accessories, fuel tank, truck and so on
Appliances: refrigerator back, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof belt, LED backlight, electrical cabinet
Agriculture: pig, shed, granary, greenhouse with pipes
Other: heat insulation cover, heat exchangers, dryers, water heaters and so on

l The concept of galvanized steel sheet
Galvanized sheet refers to the surface of a layer of zinc plated steel plate. Galvanizing is a frequently used and effective method of preserving corrosion, zinc production around half of the world are used in this process。

l Appearance of galvanized steel sheet
Galvanized sheet as a result of coating process in different ways, the surface state is also different, such as ordinary zinc flowers, fine zinc flowers, flat zinc flowers, zinc-free flowers and phosphating surface

l Galvanized steel sheet
Galvanized amount standard value: galvanized zinc coating thickness is that the thickness of a commonly used effective method. The unit for galvanizing isg/m2

l Application of Galvanized Steel Sheet
Galvanized sheet steel products are mainly used in construction, light industry, automobile, agriculture, animal husbandry and fishery and commercial industries. The construction industry is mainly used in the manufacture of anti-corrosion industrial and civil construction roof, roof grille, etc .; light industry with its manufacture of household appliances shell, civil chimneys, kitchen utensils, etc., the automotive industry is mainly used in the manufacture of car corrosion-resistant components ; Agriculture, animal husbandry and fishery is mainly used for food storage and transportation, meat and aquatic products, such as frozen processing appliances; business mainly used as storage and transportation of goods, packaging appliances, etc.
