Aluminum-Zinc Alloy Coated Steel Sheet(AZ)

- Weldability
The weldability of AZ is similar to that of galvanized steel sheet. Special attention required before welding includes the welding current, time, and electrode pressure.

- Paintability
Paint is highly adhesive to coated layer of AZ steel sheet, compared to galvanized steel plates. AZ used for general purposes does not require pretreatment before painting.

PRODUCT

Comparison of heat reflectivity by product

- Heat Reflectivity
AZ steel sheet boasts superior heat reflection, which produces increased energy efficiency, making it an excellent material for the interior of electronic home appliances. Used as a roofing material, AZ will inhibit the rise of a building's temperature, thereby lowering the cost of air conditioning. Food storage buildings made with AZ enjoy the additional benefit of having stored grains protected from quality change.

Classification

Classification By Post-treatment

- Excellent Workability
The workability of AZ is similar to that of galvanized steel sheet. Its ability to suppress fine cracks on the coating layer enhances the durability of the treatment area.

- Excellent Paintablity
Paint is highly adhesive to the coated layer of AZ steel sheet, compared to galvanized steel plates.

- Economically efficient
Available in widths of five feet (MAX 1600), AZ reduces the loss and suitable to duct and construction.

- Smooth surface
AZ is available in a delicate light silver spangle, so it is appropriate for decorative use.

- Heat Reflectivity
AZ is highly energy efficient, with superior heat reflection and low heat consumption.

- Heat Resistance
The portion of the aluminum in the coated layer of AZ is high at over 80%. AZ will withstand a prolonged temperature of 315 degrees Celsius without discoloration or oxidization.

- Excellent Durability
AZ is three to six times more corrosion resistant than zinc coated steel sheet of the same thickness. AZ is backed by a 20-year warrantee for residential use.
