Color Steel Rock Wool Sandwich Panel
Color Steel Rock Wool Sandwich Panel Product Specification
Product Overview
Color steel rock wool sandwich panel is a composite building material consisting of color-coated steel sheets as facing layers and basalt rock wool as the core material, bonded together with high-strength adhesives. Integrating fireproofing, thermal insulation, sound absorption, and decorative functions, it is an ideal enclosure material for modern industrial plants, logistics warehouses, commercial buildings, and other applications.
Product Structure
Facing Layers: Premium color-coated steel sheets (galvanized or galvalume substrate) with polyester (PE), silicon-modified polyester (SMP), or fluorocarbon (PVDF) coatings for superior weather resistance and aesthetics.
Core Material: High-density (≥120kg/m³) basalt rock wool, formed by melting basalt at high temperatures and spinning into fibers, bound with eco-friendly adhesives for uniform fiber distribution.
Bonding Layer: Polyurethane (PUR) or epoxy-based high-strength adhesives ensure permanent bonding between facings and core.

Product Advantages
Exceptional Fire Resistance: Class A non-combustible material, no molten droplets, effectively prevents fire spread.
Durable Thermal Insulation: High closed-cell rock wool structure significantly reduces heat transfer.
Superior Acoustic Performance: Three-dimensional fiber matrix effectively absorbs mid-to-high frequency noise.
Long-Term Durability:
55% aluminum-zinc alloy coating (AZ150) provides 4-6× better corrosion resistance than standard galvanized steel.
Concealed joint design eliminates thermal bridging.
Eco-Friendly: CFCs/HCFCs-free, compliant with LEED green building standards.
