Galvalume steel coils with excellent corrosion resistance
Mar 20, 2018

Brief Introduction:
Galvalume steel coils is hot or cold-rolled strip steel belt of substrates, through continuous hot-dip galvalume process.It is good in corrosion resistance,high surface quality, convenient in deep-processing,low cost. Widely used in silo, chimney, kitchen utensil, construction formwork, household electrical appliance, roller shutter door, garage door,etc.

Parameters:
1) Formable, weldable and paintable
2) Superior long term corrosion resistance in the most atmospheric conditions. This is achieved through the combination of the sacrificial protection of the zinc and the barrier protection of the aluminum
3) Hot dip galvalume coating out-perform galvanized coating from 2-6 times than hot dip galvanized steel

 

Usage:

Infrastructure : Roofing; External Siding; Garage; Shutter;
Household Appliances :Oven; Air-Conditioning Ventilation System; Solar Water Heater; Electronics;
Automobile : Mobile Muffler; Vent Pipe; Catalysis Converter Heater Shield; Bottom Accessories;
Industrial Instrument : Electric Control Cabinet; Industrial Freezer Chest; Dispenser;
