Fireproof Rock Wool Insulated Steel Structure Factory Warehouse Building Anti Corrosion Galvanized Frame Large Span Storage Facility

Fireproof Rock Wool Insulated Steel Warehouse Building

Safety-critical storage demands the highest fire protection standards. Our fireproof steel warehouse features Class A non-combustible rock wool sandwich panels with 60-120 minute fire resistance ratings, providing essential life safety protection and insurance compliance for warehouses storing flammable materials, high-value inventory, or operating in industrial zones with strict fire codes.

Comprehensive Fire Safety Design

• Class A Fire Rating: Rock wool core material (100-120 kg/m³ density) is completely non-combustible with a melting point above 1000°C. Tested and certified to meet GB 8624 Class A and EN 13501-1 A1 fire classification standards.
• Fire Compartmentalization: Rock wool panels create effective fire barriers between warehouse zones, limiting fire spread and protecting adjacent storage areas. 75mm roof panels provide 120-minute fire integrity, while 50mm wall panels deliver 60-minute fire resistance.
• Integrated Safety Systems: Roof structure pre-engineered to support automatic sprinkler systems, smoke detectors, and fire alarm wiring conduits. Roof purlin design includes hanging point reinforcement for sprinkler pipe support.
• Hot Dip Galvanized Frame Protection: All structural steel receives ≥80μm hot-dip galvanized coating, protecting the load-bearing frame from corrosion even after fire exposure and subsequent water damage from sprinkler activation.

Beyond Fire Safety

Rock wool panels also provide excellent thermal insulation (≤0.045 W/(m·K)) and acoustic absorption (NRC 0.75-0.90), creating a quieter, more temperature-stable warehouse environment that protects both workers and stored goods.

Certification & Compliance

Our factory holds ISO 9001:2015 and CE certifications. Fire test reports and material certificates are available for building permit submission and insurance documentation. Full material traceability from raw mineral wool to finished panel assembly.
