G550 SGLCC Minimum Spangle Steel Gl Coils Zincalume ISO9001

G550 SGLCC Minimum Spangle GL Steel Coil ISO9001 Zincalume Coil

Aluzinc steel is the composition of coating 55% aluminum, 43.4 % zinc and 1.6 % silicon. The coating is also applied by means of a continuous hot dip galvanizing process. Aluzinc-zinc coating offer an excellent corrosion resistance resultant from the barrier effect of the aluminum on the surface and the sacrificial protection of zinc. Aluzinc has a clean, natural and bright silvery surface. The surface includes small spangles that give it a lustrous and striking appearance as light conditions change.

Aluzinc is the world’s fastest growing metallic coating. This is due to the fast of combined strength, formability and recyclability of steel with the proven long term anti- corrosion performance of the AI-Zn alloy coating. This combination results in an economical product with superior eco-friendliness attributes of durability, recyclability, energy efficiency and scarce resource utilization.

We manufacture Continuously Hot Dip Galvalume (GL) Coils as per the below Standards

ASTM A792/A792M – 10(2015)
This is the American standard for cold rolled hot dip Galvalume steel materials.

JIS G 3321 :2010
This is the Japanese material standard associated with hot dipped Galvalume steel coils.

EN 10346:2015 which Supersedes BS EN 10327:2004 & BS EN 10326:2004 
This is the European material standard for continuously hot-dip coated steel flat products.

Advantages

• Good corrosion resistance at high temperatures
• Good abrasion resistance because of its surface hardness
• Excellent thermal and light reflectivity.

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.
