55% Non AFP AZ150 Galvalume Steel Sheet 610mm coil ID

55% Galvalume Steel Sheet Non AFP AZ30-AZ150

Galvalume steel sheet introduction:

Galvalume Steel Coil is the idea alloy of aluminum and zinc . The surface is bright and clean ,the size is accurate ,the plate surface is straight , the zinc flower is even and beautiful . After its surface is finished , it is a good substrate for making anticorrosive coating plates .  55% aluminum, 43.4% zinc and 1.6% silicon at 600 C. The whole structure is composed of aluminum, one iron, one silicon and one zinc, forming a compact four element crystal. Heat resistance of the product is much better than ordinary galvaume steel coil , and almost equal to the Aluminum coil.

Galvalume Steel Coil Features:

Thermal Reflection:

People use it as material for heat-insulation for its thermal reflectivity as high as twice the galvanized steel sheet.

Heat-resistance:

The aluzinc steel sheet could bear above 300℃ high temperature with its good performance in heat-resistance, quite similar to the aluminized steel sheet’s performance in oxidation-resistance under high temperature. It is often used for chimney pipe, oven, illominator, and fluorescent lamp cover.

Corrosive-resistance performance:

The essential of galvalume steel coil’s corrosive-resistance lies at aluminium’s protective property. Once the zinc come under abrasion, the aluminium would form a layer of densified oxidized aluminium, preventing the interior from further corrosion.

Economical:

The density of 55%AL-Zn is smaller than Zn, therefore, with the same weight and thickness of coating, the galvalume steel sheet is 3% larger in area than that of galvanized steel sheet.

Easily painted:

There is perfect adhesiveness between galvalume sheet and paint, saving the process of pre-treatment and weathering for painting work.

The coating material on the galvalume steel sheet is outstanding in its adhesiveness, which could be directly tarring on the advertising board and commonly used board with no pre-treatment such as weathering process.

The galvalume steel sheet’s surface is luxury in silver colored appearance.
Galvalume steel sheet and galvanized steel sheet are similar in performance of processability and painting.
