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.
- Good corrosion resistance at high temperatures
- Good abrasion resistance because of its surface hardness
- Excellent thermal and light reflectivity.
The improved corrosion resistance of 55% Al-Zn Alloy Coated Steel Coils are derived from the unique combination of the barrier protection of Aluminum and the sacrificial protection of Zinc. The formation of an insoluble Aluminum oxide layer provides the barrier protection while Zinc provides a sacrificial protection at cut edges, scratches and areas of coating damage.
Similar to the Aluminum Coated Steel Sheet that can resist high temperature oxidation, 55% Al-Zn Alloy-Coated Steel Sheet demonstrates better resistance to high temperature.
HEAT TRANSMISSION & REFLECTIVITY
55% Al-Zn Alloy-Coated Steel Coil has a high reflectivity value making it an effective barrier against heat.
