Alu-Zinc Coated Steel (GL)

Product introduction

Detail view off

Excellent Durability

GL is three to six times more corrosion resistant than zinc coated steel sheet of the same thickness.

Heat Resistance

The capacity ratio of the aluminum in the coated layer of GL is high at over 80%. GL will withstand a prolonged temperature of 315 degrees Celsius without discoloration or oxidization.

Heat Reflectivity

GL is highly energy efficient, with superior heat reflectivity and low heat consumption.

Smooth surface

GL is available in a delicate light silver spangle, so it is appropriate for decorative use.

Economically Efficient

Available in widths of five feet (MAX 1600), GL reduces the loss and suite to duct and construction.

Excellent paintability

Paint is highly adhesive to the coated layer of GL steel sheet, compared to galvanized steel plates

Excellent Workability

The workability of GL 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.
