China Suppliers Factory for Galvalume Steel Coil (Aluzinc) - High Corrosion Resistance and Eco-Friendly Coating
Description & 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
This is the European material standard for continuously hot-dip coated steel flat products (Supersedes BS EN 10327:2004 & BS EN 10326:2004).
Advantages
Good corrosion resistance at high temperatures
Good abrasion resistance because of its surface hardness
Excellent thermal and light reflectivity.
Key Properties
Corrosion Resistance
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.
Heat Resistance
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.

Frequently Asked Questions
1. What standards do your Aluzinc Coated Steel Coils comply with?
Our materials comply with major international standards including ASTM A792/A792M (American standard), JIS G 3321 (Japanese standard), and EN 10346 (European standard for continuously hot-dip coated steel flat products).
2. What are the key advantages of Galvalume steel coils?
Galvalume steel offers superior corrosion resistance at high temperatures, excellent abrasion resistance due to its surface hardness, and outstanding thermal and light reflectivity.
3. How does the 55% Al-Zn alloy coating protect the steel from corrosion?
The coating combines the barrier protection of Aluminum, which forms an insoluble Aluminum oxide layer, with the sacrificial protection of Zinc at cut edges, scratches, and damaged areas.
4. What are the typical applications for Aluzinc Coated Steel?
It is widely used in building & construction, agricultural equipment, computer appliances, transportation, furniture, and various electrical appliances.
5. What sizes and specifications are available for these coils?
We offer thicknesses ranging from 0.1mm to 1.5mm, widths from 600mm to 1500mm, zinc coat weights from 40g/m² to 180g/m², and coil weights between 3 to 7 tons.
