Product Description

Product Description

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

1. Galvalume steel contains 55% aluminum, 43.5% zinc, 1.5% silicon and other microscale component.
2. 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.
3. 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.
4. High reflection to heat and light. The reflection ratio of galvalume steel is above 0.7, twice bigger as the galvanized steel at the same coating level.
5. High temperature resistance: galvalume steel can bear high temperature over 300 Celsius degree for more than 120 hours.

Production Process

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.
HERE IS THEORETIC DIAGRAM:OUR PRODUCING LINE:

Surface treatment type and function
Surface treatment	Function & Features
Chemical passivating treatment	minimize the chance of white rust forming during the transit and storage
Oiled	minimize the tendency for storage and transit stain
passivating + oiled	provide the protection from the storage and transit stain by special chemicals called corrosion inhibitors
Anti-Fingerprint	Transparent and thin organic resin film adhere to the coil surface.So the fingerprint stain can be avoided,and enhancing the anti-corrosion property.
Chromated	Passivation treatment with chrome,enhancing the anti-corrosion property,so the base metal can get better protection;giving steel coil a dim color as surface appearance
Skin passed	Steel coil will become more straight and flat, getting an even and consistent appearance,enhancing the adhesion;

This is the principle diagram of anti damage and corrosion:
