Rockwool Sandwich Panel

This panel combines a color-coated steel exterior with a rockwool core – an inorganic fibre material that delivers excellent fire resistance, thermal insulation, and sound absorption. The core does not burn and can withstand high temperatures, making it a reliable choice for projects where fire protection is a priority. At the same time, the dense fibre structure reduces noise transmission, creating a quieter indoor environment. The continuous production process ensures uniform core density and strong bonding with the steel facings, giving the panel stable mechanical properties over its service life.

The rockwool core resists deformation under normal service conditions, and the panel maintains a flat, straight profile even after long-term use. The tongue-and-groove joint design simplifies alignment and speeds up installation, reducing on-site labour time. The finished wall surface is smooth and even, requiring minimal joint finishing – an advantage for cleanroom and industrial applications where wall flatness matters.

Our factory has two decades of experience in producing sandwich panels, supported by a dedicated R&D team and a 5,000 m² production base. We source high-quality raw materials and run strict in-process checks, from steel coiling to core foaming and final cutting. Every batch undergoes a final inspection before packaging to confirm that dimensions, core density, and surface finish meet the order specifications. Although we do not offer OEM/ODM services, our standard product line covers most project requirements, and we can guide buyers in choosing the right configuration.

Panel thickness is available in 50 mm, 75 mm, and 100 mm, with a standard width of 1150 mm and length made to customer request. Steel facings can be selected from 0.35 mm to 0.5 mm colour-coated steel, or stainless steel for enhanced corrosion resistance. Typical production lead time is about 10 working days for standard orders, and we provide regular updates on manufacturing, inspection, and loading status – helping buyers coordinate with their construction schedules. Packaging is arranged to prevent transit damage, and loading is organised per order quantity.

This rockwool sandwich panel is commonly used in electronics manufacturing, pharmaceutical production, food processing plants, laboratories, hospital clean zones, industrial factories, warehouses, logistics centres, public buildings, and various purification projects. Its balanced fire performance, thermal insulation, and acoustic control make it a versatile solution for both wall partitions and ceiling systems.
