G550 Full Hard AZ150 GL Steel Coil Galvalume Aluzinc Steel Coil

G550 Full Hard AZ150 55% AL GL Steel Coil Galvalume Steel Supplier

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.

We has both GL coil and sheet for sale, which are available from AZ30 to AZ150. The thickness is from

0.12 to 1 mm and the width is from 600 to 1,250 mm. Moreover, we offer cutting, slitting, and profiling services.

Welcome to contact us for samples or visit our factory.

What Does AZ150 Mean?

AZ150 means that in the triple spot test in the en 10346 standard, the minimum total coating mass on both surfaces of the aluminum-zinc alloy coating is 150g per square meter. Equivalent to Total Both Sides in ASTM a792 standard is 0.50 oz/square foot.

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.

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 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.
