Description
The sandwich panel features high-strength color-coated galvanized steel sheets as the outer skins, combined with a rock wool core and polyurethane sealing at the panel joints. This structure provides a balanced combination of weather resistance, fire protection, thermal insulation, and reliable sealing performance, making it suitable for industrial buildings, warehouses, cold storage facilities, and other roofing applications.
Color-Coated Galvanized Steel Skin
The panel uses color-coated galvanized steel sheets as the outer skins, providing excellent corrosion and weather resistance. The coated surface helps protect the panel against rain, moisture, UV exposure, and common environmental conditions while maintaining a clean and attractive appearance. Different coating colors and finishes can be selected according to project requirements.
Fire-Resistant Rock Wool Core
The core is made of rock wool, an inorganic insulation material with excellent fire resistance and thermal stability. It helps improve the overall fire safety of the roofing system while also providing effective thermal insulation and sound absorption.
Polyurethane Joint Sealing
Polyurethane material is applied to the panel joints and connection areas to create a reliable sealing structure between adjacent panels. Its good adhesion, elasticity, and water resistance help reduce air leakage and moisture penetration, improving the overall waterproofing and airtightness of the roof system.
