PPGI Gl Al Gi Coilgalvanized Zinc Coated

Product Description

1.Galvalume Steel Coil, also known as Aluminum zinc alloy Steel Coil, or alu zinc steel coil, has better mechanical advantages than traditional material.

2.Galvalume steel contains 55% aluminum, 43.5% zinc, 1.5% silicon and other microscale component.

3.Galvalume steel coil possesses extreme anti-corrosion property. It adopts aluminum as the oxidation film, and also the zinc-iron electrochemistry principle , which makes the anti-corrosion property 2~5 times better than galvanized steel at the same coating level.

4.Galvalume steel coil possesses the amazing appearance known as diamond grain. This nice appearance can be applied on building interior decoration, and exterior decoration panel.

ProductionProcess

The core procedure of galvaluming process is putting the carbon steel sheet into the molten aluminum zinc pot, about 450 Celsius degree, then an alu zinc layer film adhere to the base carbon steel sheet.
Simplifeid producing process outline:
Decoiling - Cleaning - Annealing - Aluminum Zinc pot -Air knife - Cooling Tower -  Straightening and Passivation - Post-treatment - Recoiling

Detailed Steps Of The Galvalume Steel Sheet Processing

Step 1:
Pre-treatment: When the cold rolled coil arrives at the workshop,firstly going  through the uncoiler machine, through the degreasing section and the reduction furnace, the steel coil surface is cleaned and the components are adjusted to the proper ratio for the next galvalumng procedure.
Step 2:
Core section: The uncoiled steel sheet goes into the molten aluminum zinc pot. After the pot, dense alu zinc layer adhere to the surface of the steel sheet. Then it is cooled and shaped by the cooling tower.
Step 3:
Post-processing: The steel sheet comes into the post-processing stage. Going through procedures including finishing, straightening and passivation, finally recoiling. At this point, the well known 55% galvalume steel coil is done.
