aluminum zinc plating

Aluminum galvanized sheet coil

Aluminum zinc plated steel plate is composed of aluminum zinc alloy structure, which is composed of 55% aluminum, 43% zinc and 2% silicon solidified at 600 ℃. Its whole structure is composed of aluminum iron silicon zinc, forming a dense quaternary junction crystal. Aluminum zinc plated steel plate is an important alloy material often used in daily life.

Product features

Aluminum zinc plated steel plate has many excellent characteristics: strong corrosion resistance, which is three times that of pure galvanized steel plate; There are beautiful zinc flowers on the surface, which can be used as building exterior panels.

Corrosion resistance

The corrosion resistance of "aluminized zinc steel coil" is mainly due to the protective function of aluminum and aluminum. When zinc is worn, aluminum forms a dense layer of alumina to prevent corrosion-resistant substances from further corroding the interior.

Heat resistance

Aluminum zinc alloy steel plate has good heat resistance and can withstand a high temperature of more than 300 degrees Celsius. It is very similar to the high-temperature oxidation resistance of aluminum plated steel plate and is often used in

Chimney tube, oven, illuminator and fluorescent lampshade.

Thermal reflectance

The heat reflectivity of aluminized zinc steel plate is very high, which is twice that of galvanized steel plate. People often use it as heat insulation material.

Economy

Because the density of 55% Al Zn is smaller than that of Zn, the area of aluminum zinc plated steel plate is more than 3% larger than that of gold plated steel plate under the condition of the same weight and the same thickness of gold plating layer.

Product use

Architecture: roof, wall, garage, sound insulation wall, pipeline and combined house, etc

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

Household appliances: refrigerator back plate, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof belt, LED backlight, electrical cabinet, etc

Agriculture: pig house, chicken house, granary, pipeline for greenhouse, etc

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

Precautions for use

Safekeeping: it should be kept indoors in the warehouse, keep dry and ventilated, and do not store it in acidic climate for a long time. Outdoor storage shall be protected from rain to avoid oxidation spots caused by condensation.

Transportation: avoid external impact, use ski to support steel coils on transportation tools, reduce stacking and take rainproof measures.

Processing: during coilcenter shear processing, the same lubricating oil as aluminum plate shall be used. When drilling or cutting aluminum zinc plated steel plate, the scattered iron filings shall be removed in time.
