rock wool sandwich panel

Metal sandwich wall panels, with their excellent thermal insulation performance, lightweight nature, prefabrication capability, outstanding fire resistance, and rapid installation, have become the preferred material for the exterior wall cladding of steel structure buildings. They are widely used in steel structure factories, cold chain warehouses, logistics warehouses, clean rooms, and more.   Compared to traditional brick and concrete walls, metal sandwich wall panels offer the following advantages:   1. Particularly suitable for steel structures, significantly reducing costs and increasing efficiency: Sandwich wall panels utilize a composite structure of "color steel panels + insulation core material," weighing only 1/30th of traditional walls. This effectively reduces the load on steel beams, columns, and foundations, decreasing overall steel consumption. All wall panels are prefabricated in the factory according to drawings and installed on-site using bolt assembly, eliminating the need for cement work and shortening the construction cycle by more than 50%, facilitating rapid project completion and commissioning.   2. Multiple core material options to suit different needs: PIR polyurethane sandwich panels: low thermal conductivity and excellent insulation performance. Suitable for large cold storage facilities, temperature-controlled workshops, food processing plants, etc., significantly reducing refrigeration energy consumption. Rock wool sandwich panels: Class A non-combustible material, suitable for factories, warehouses, public buildings, etc., with high fire protection requirements. EPS sandwich panels: Good thermal insulation, lightweight, and low price. Suitable for general processing workshops, temporary prefabricated buildings, etc.   3. Long service life and low maintenance costs: Metal sandwich wall panels use aluminized zinc base material with PE or fluorocarbon coating, which is corrosion-resistant, UV-resistant, and salt spray-resistant. With regular maintenance, the service life can reach more than 20 years, and the long-term maintenance cost is low.
