Product Details
The 820mm wide color steel roof sheet is a common building material with unique structure, characteristics, wide application scenarios and significant advantages. It is one of the indispensable and important materials in the construction industry.
The w820 type roof sheet is a profiled plate formed by color-coated steel plate and cold bending by roller. Its structure usually includes multiple corrugated or ribbed sections for added strength and stability. These corrugated or ribbed sections allow the color steel roof panels to more effectively distribute the load when stressed, thereby increasing their load-bearing capacity.
Features of w820 type roof sheet
1. Light weight: Color steel roof sheets are relatively lightweight, which helps reduce the overall weight of the building and reduce foundation treatment costs.
2. High strength: Although light in weight, color steel roof sheets have high strength and stability and can withstand greater wind and snow pressure.
3. Thermal insulation: Color steel sheets have good thermal insulation properties, which can effectively reduce building energy consumption and improve building energy efficiency.
4. Waterproof and anti-corrosion: The specially treated color coated metal sheets have excellent waterproof and anti-corrosion properties, which can effectively extend the service life.
5. Convenient construction: The installation of color coated steel roof sheet is simple and fast, greatly shortening the construction period.
