Analysis of the characteristics of galvalume steel plate

Galvalume steel plate is widely used in building materials, home appliances, automobile, environment, machinery, ships and many other fields of a alloy plating steel plate. galvalume steel plate is coated with aluminum zinc alloy on the surface of the steel plate, which is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at 600℃. The whole structure is composed of aluminum, iron, silicon and zinc, forming a dense quaternary crystal alloy plating steel plate.

 

 

 

The corrosion resistance of "galvalume steel plate" is mainly due to aluminum, the protective function of aluminum. As the zinc wears away, the aluminum forms a dense layer of alumina, preventing corrosion resistance from further eroding the interior.

 

 

Aluminum-zinc alloy steel plate has good heat resistance, can withstand the high temperature of more than 300 degrees Celsius, and aluminum-plated steel plate high temperature oxidation resistance is very similar, often used in chimney pipes, ovens, illuminators and solar lampshades.

 

 

The thermal reflectance of galvalume steel plate is very high, which is twice that of galvanized steel plate. People often use it as insulation material.

 

 

Because the density of 55%AL-Zn is smaller than that of Zn, the area of galvalume steel plate is more than 3% larger than that of galvanized steel plate in the case of the same weight and the same thickness of gold plating.
