Az150 Zincalume GL Steel Coil Bobina Galvalume AFP Surface

Product Specification

Az150 Hot Dipped Zincalume GL Steel Coil AFP Aluzinc Steel Bobina Galvalume

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.

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.

Benefits of Using Aluzinc Steel

• Extreme Corrosion Resistance: Compared to wooden or plastic beds, Aluzinc is 7x more resistant to corrosion and rust, and 3-7x more resistant than regular galvanized steel. The corrosion rate (the thickness of the Aluzinc coating lost every year in normal environments) is a maximum of 20% of one micron (0.2 μm). Theoretically, the useful life of Aluzinc in normal environments is more than 100 years. In real life, Aluzinc has lasted more than 20 years in severe marine environments, though in the first year the coating loses up to 0.4 μm.

• Superior Heat Reflection: Aluzinc Steel has superior Albedo capacity. Albedo is another name for reflectivity, a measurement of how much light that hits a surface is reflected without being absorbed. Research shows that soil in galvanized steel stays at an optimal and more even temperature when compared with wooden, concrete and dark plastic beds, which soak up summer sun during the day and stay hot into the night. Research also shows that galvanized steel beds have extra benefits of improved fruit set rate, blush color and maturity.

• Incredibly High-Strength: The surface of Aluzinc is twice as hard as regular galvanized steel, and more than 5x harder than wood or plastic. With high wear resistance, Vego raised beds hold soil for decades without deforming.

• No Soil Contamination: While treated wood and plastic degraded under extreme temperatures, Aluzinc material will not leaches chemicals into plants or soil. This helps create the highest quality soil for organic gardening.

• 100% Green and Recycle Material: With a long useful life, Steel is an environmentally-friendly material made using a "green process." Not only is it 100% recyclable, steel is also the world’s most recycled material.

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.
