CGCC Galvanized Steel Corrugated Roofing Sheet

Compared with some ordinary galvanized steel sheets on the market, our CGCC roof panels are not only corrosion-resistant, but also superior in beauty, durability and impact resistance. We use a strict coating control process to ensure that each layer of coating is even and firm, thus avoiding the uneven coating or easy peeling of some products on the market. Even under long-term sun and rain, they can still provide excellent protection, prevent rust and extend service life.
Our roof panels are not only tough, but also have good flexibility, which is very suitable for large-scale installation or complex shapes. Even if they are bent during construction, they will not easily crack or warp, which improves the use effect and installation convenience.
Our CGCC also provides a variety of colors and surface treatment options, which are not only beautiful, but also ensure durability and brightness under different light and climate conditions. Especially in terms of wind resistance and strength, our products have passed rigorous testing and are very suitable for areas with strong winds or extreme climates.

Other Infomation

When installing CGCC galvanized steel roof panels, following the appropriate steps can better ensure the installation quality of CGCC galvanized steel panels and extend their service life. The following is a simple and easy installation guide for your reference:

1. Preparation: First, check whether all panels and tools are intact, including screws, electric drills, sealants, etc. Accurately measure the installation area and cut the panels if necessary to ensure that each panel fits perfectly.

2. Choose the right connection method

Overlap: Fix the panels in place by overlapping the edges, suitable for general waterproofing needs and easy installation.
Bite edge: Buckle the edges of the panels to make the joints tighter, greatly improve the waterproofing effect, especially suitable for roofs and exterior walls.
Buckling: Special folding treatment is performed on the edges of the panels to enhance strength and wind resistance, suitable for areas with high wind pressure.

3. Installation order: Install from the bottom of the eaves step by step upward, ensuring that the lower end of each panel is slightly tilted outward to help rainwater drain smoothly and reduce water accumulation.

4. Waterproof sealing: Use sealant or waterproof gaskets on screws, joints and edges to effectively block moisture infiltration and further improve the waterproof effect.

5. Post-completion inspection: Finally, check whether all screws and joints are tight, and clean up the metal shavings generated during the installation process to prevent scratching the surface of the board or causing rust.
