Galvalume steel corrugated roof sheet has designs of wavy, trapezoidal designs, ribbed galvanized roof panels, etc. It can be used as a single-layer board, covering an existing roof, or a steel sandwich panel. Galvalume sheet itself is more cost-effective than traditional roofing materials. In addition, it is light in weight and easy and quick to install. In addition, it is durable and recyclable and requires less maintenance. All these factors make galvalume steel corrugated roof sheet an economical choice. It has a bright and smooth surface. The corrugated design is also excellent from the outside. In addition, it has good adhesion, so you can paint it in different colors. Having a galvalume steel roof makes it easy to achieve aesthetic purposes.

Superior Corrosion Resistance

The aluminum layer makes the aluminized zinc steel have excellent corrosion resistance. When the zinc wears, the aluminum will form a dense aluminum oxide layer, preventing the corrosion-resistant substance from further corroding the interior. Therefore, the corrosion resistance of GL plate is 3 times that of galvanized plate. Under the same circumstances, the service life of GL roof panels is 2-6 times that of GI roof panels.

High Thermal Reflectivity

Its reflection coefficient is twice that of galvanized metal roof panels, which can reduce the indoor temperature in summer and reduce the power consumption of air conditioning. This feature makes it ideal for hot climates.

High Temperature Resistance

GL roofing sheet has good heat resistance and can withstand high temperatures above 300 degrees. Therefore, it can be used for a long time at high temperature.

Smooth Surface, Uniform Appearance

The aluminized zinc roof panels are smooth, silvery white with uniform sequins. It looks beautiful and can be used directly. Therefore, it is widely used for commercial and residential purposes.

Good Formability And Adhesion

The adhesion between the GL coating and the paint is good and easy to paint. In addition, it also has excellent formability. That is, punching, cutting, and the like are easy.
