Four Characteristics Of Galvlalume Steel Coil
- Mar 08, 2017 -

Generally,Galvlalume Steel coil divided into four characteristics:

Thermal reflectivity:

The heat reflectivity of galvanized steel is very high, is two times that of galvanized steel plate material, people often use it to make heat insulation.

Heat resistance:

Aluminium zinc alloy steel coil has good heat resistance, can withstand the high temperature of more than and 300 degrees Celsius, and high temperature oxidation resistance of aluminized steel plate is very similar, often used in chimneys, oven, lighting device and fluorescent lamp shade. Corrosion resistance:

The corrosion resistance of aluminum zinc steel coil mainly because of aluminum, aluminum protection. When the zinc is worn, the aluminum forms a dense layer of alumina to prevent further corrosion of the corrosive substance.


Because the 55%AL-Zn Zn density than the density, so the same weight and the same thickness of gold case, galvanized steel plated than the large area of more than 3%.

Easy to paint:

With excellent adhesion between aluminum zinc plate and paint, can be painted without pretreatment and weathering.

Coating adhesion of galvanized steel plated layer is more excellent, so without Weathering pretreatment, can also directly in the advertising board and general board of coating.
