Specification

Key Benefits

-Integrated fire resistance thermal insulation : Our 50mm sandwich panel is filled with high-density rock wool core, reaching A1 non-combustible grade with outstanding fire resistance to prevent flame spreading. Meanwhile, the dense rock wool structure provides stable thermal insulation, cutting heat and cold transfer and helping customers reduce long-term building energy costs.

-Efficient sound absorption : The rock wool core has natural porous structure with excellent sound absorption performance. It effectively absorbs industrial noise and indoor echo, creating a quiet working space for factories, warehouses and partition projects.

-High corrosion resistance & long service life : With premium sturdy color steel plate as surface layer, this fire resistant sandwich panels features strong anti-corrosion and weather resistance. It avoids rust and aging in harsh environments, lowering daily maintenance expenses and extending service life.

-Easy quick installation : Integrated modular design allows flexible splicing and simple on-site operation. It requires no complicated construction steps, greatly shortening construction period and saving labor and time cost for engineering projects.

FAQ

Q: Can 50mm rock wool sandwich panels be used for both wall and roof cladding? What are their advantages compared to other fireproof sandwich panels?

A: Yes. Our 50mm sandwich panels are high-performance fireproof sandwich panels. The core is high-density rock wool (85-150kg/m³), and the surface is made of color-coated steel sheet, making them perfectly suitable for industrial building wall and roof cladding. Compared to other fireproof sandwich panels, it has A1-level non-combustible performance, superior thermal insulation and sound insulation, and is lighter and easier to install. The color-coated steel sheet is treated with anti-corrosion, and the rock wool core has a waterproof rate of ≥98%, enabling it to withstand harsh environments and ensuring long-term stable use of walls and roofs, meeting the needs of industrial scenarios.

Q: Can 50mm sandwich panels be customized to our specific size requirements?

A: Yes. We support customization services for 50mm sandwich panels. The effective width can be adjusted between 950mm and 1150mm as needed, and the length can be customized according to the actual needs of the project. Customized products still maintain A1 fire resistance and the original core advantages, perfectly matching your construction needs.
