Introduction of galvanised steel sheet :

Galvanized steel sheet is one of the most widely used products, used extensively in the building sector, automotive, agricultural and other areas where the steel needs to be protected from corrosion.

Description of galvanised steel sheet :

Details of galvanised steel sheet  :

Characteristics of galvanised steel sheet :

Advantage of galvanised steel sheet  :

• Strong corrosion resistance, 3 times that of galvanized steel coil.
• The density of 55% aluminum is smaller than the density of zinc. When the weight is the same and the thickness of the plating layer is the same, the area of the galvalume steel sheet is 3% or larger than that of the galvanized steel sheet.

Surface Treatment Of galvanised steel sheet :

Detailed Steps Of The galvanised steel sheet Processing

Step 1:

Pre-treatment: After the cold-rolled coil arrives in the galvalume workshop, after passing through the uncoiler, through the degreasing section and the reduction furnace, the steel coil is cleaned and its components are reduced to the extent that it can be galvanized.

Step 2:

Central section: The most critical technology is this step. After passing through the zinc pot, a layer of zinc layer is plated on the surface of the steel plate. After coming out of the zinc pot, it is cooled and shaped by the cooling tower.

Step 3:

Post-processing: The steel plate finally comes to the post-processing stage after various processes. After finishing, straightening and passivation, and finally coiling.

Galvanised steel sheet 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.
