G550 0.12-2mm GL Steel Coil AZ150 GI JIS Full Hard Aluzinc Coil
The GL & aluzinc steel sheet in coil uses the cold-rolled steel sheet as a substrate and solidified by 55% aluminum,
43.4% zinc and 1.6% silicon at 600 °C. It combines the physical protection and high durability of aluminum and the electrochemical protection of zinc. It is also called aluzinc steel coil.

AZ150 Coating Thickness
AZ150 coating single surface coating thickness is 18 microns, double surface coating thickness is 36 microns.
This steel’s coating alloy is made up of 55% aluminium, 43.4% zinc, and 1.6% silica. The coating of this steel serves as general corrosion’s passivating barrier. The other coating layer allows the formation of galvanic element once the sheet is exposed to electrolyte or moisture. This exposure results in the flowing over of zinc ions and corrosion protection of exposed steel. It also helps protect the steel’s trimmed edges and scratches.
AZ150 galvalume is suitable for buildings or other facilities in extreme environments. It is extremely corrosion-resistant and weather-resistant and can reach a service life of more than 10 years.
Applications For Galvalume Steel Sheet
Construction: civil and industrial building roofs, facades, substrates for painted rolls, garage doors.
Industrial instruments: electric control cabinets, industrial freezers, vending machines.
Usually, building roofs are the most widely used.
Some regular usages:
The product can be utilized in construction industry such as roof garage,and pipes, household electricity appliances
industry such as refrigerator's back plate, air conditioner; and microwaves, and automobile industry's gas vent, fuel tank etc.
Product Advantages:
Resistant to Corrosion; Lightweight; Energy Efficient; Affordability; Longevity; Versatility;
Production process of GL coil:
Decoiling – Cleaning – Annealing – Zinc pot – Cooling – Air knife – Straightening – Post-treatment – Coiling
Detailed Steps Of The Galvalume 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 sheet. 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.
