Stainless Steel Sandwich Panel
Stainless steel sandwich panels combine a high-density rock wool core with stainless steel facings for roofing and wall applications in industrial, commercial, and residential construction. The rock wool core, produced from basalt through high-temperature melting and fiberization, provides non-combustible insulation between structural stainless steel layers.
These panels achieve fire resistance ratings up to EI 120, thermal conductivity of 0.043 W/mK, and sound insulation up to 35 dB. They resist moisture, corrosion, and chemicals while maintaining dimensional stability across temperature variations. Available thicknesses range from 50-200 mm with steel sheet options of 0.4-0.8 mm thickness.
Standard widths include 950 mm, 1000 mm, or 1150 mm, with customizable lengths up to 12,000 mm. Rock wool core density typically ranges 100-140 kg/m³, contributing to mechanical strength and insulation performance. The materials contain no Chlorofluorocarbon (CFC), Hydrochlorofluorocarbon (HCFC), or asbestos.
Manufacturing uses automated production lines bonding pre-formed stainless steel sheets to rock wool cores with high-strength adhesives. Installation involves mechanical fasteners with neoprene washers for weather tightness. Maintenance requires periodic inspection and cleaning with mild soap, avoiding abrasive chemicals to preserve the stainless steel finish.
