Thermal Insulation Cold Room Building Manufacturer in China

Especificaciones y Cumplimiento

Reference specs for our Steel Structure Warehouse Building platforms. Custom configurations available — these are starting points, not limits.

Thermal Insulation: Engineered for Consistent Temperature Control & Energy Savings

We design and manufacture steel structure cold rooms with precision-engineered thermal insulation systems — not just added layers, but integrated performance. Our standard sandwich panels use certified rock wool (density ≥120 kg/m³) or PU cores (thermal conductivity ≤0.022 W/m·K), tested to maintain stable internal temperatures from –30°C to +50°C under real-world ambient fluctuations.

• Verified cold retention: Independent SGS testing confirms ≤0.8°C/h temperature drift in –25°C rooms (at 35°C ambient, 60% RH)
• No condensation risk: Vapor barrier lamination and continuous joint sealing prevent interstitial moisture buildup — critical for food, pharma, and e-commerce fulfillment centers
• ROI-driven specs: Choose R-values from R-12 (standard warehouse) to R-32 (pharma-grade cold storage) — all pre-engineered into structural panels, eliminating field-installed insulation labor
• Compliance-ready: Meets EN 13501-1 (fire classification B-s1,d0), ASHRAE 90.1, and China GB 50019 standards — no retesting required for EU, US, or GCC market entry

Cold Room: Fully Integrated, Turnkey Cold Storage Buildings — Factory-Pretested & Shipment-Ready

Our cold rooms are not retrofitted sheds — they’re purpose-built steel structure buildings engineered as complete environmental control systems. From foundation anchor design to refrigeration interface points, every component is validated for low-temperature operation before shipment.

• Zero on-site commissioning delays: All panels pre-fitted with gasketed, cold-room-rated seals; factory pressure-tested at –30°C (leak rate ≤0.5 Pa/min)
• Plug-and-play integration: Pre-cut openings, reinforced mounting frames, and standardized flange dimensions for direct connection to Carrier, Bitzer, or Danfoss refrigeration units
• Scalable capacity: Modular design supports single-zone rooms (50 m²) up to multi-compartment facilities (5,000+ m²) — all built to same ISO 9001-certified production line
• Life-cycle assurance: 50-year structural warranty includes cold-specific corrosion protection (Z275 galvanized steel + epoxy-polyester coating, salt-spray tested ≥2,000 hrs)

Building: High-Strength, Rapid-Assembly Steel Structure Buildings — Designed for Global Site Conditions

We deliver fully engineered steel structure buildings — not generic kits. Each structure is individually calculated using Tekla Structural Designer and SAP2000, factoring in your exact location’s wind, snow, and seismic loads — ensuring compliance without over-engineering or hidden reinforcement costs.

• Site-adaptive foundations: Optional ground-screw, concrete pier, or ballasted slab solutions — all pre-designed for your soil report and local code (IBC 2021, Eurocode 3, AS/NZS 1170)
• Speed-to-operation proven: Average erection time: 12–18 days for a 1,000 m² cold room (with our supervised installation team); 30% faster than traditional concrete builds
• Load-certified flexibility: Standard roof live load capacity: 0.5 kN/m² (upgradable to 2.0 kN/m²); crane runway beams rated to 10-ton capacity — no redesign needed for future operational expansion
• Logistics-optimized delivery: All components shipped flat-packed in 40’HC containers (max. 1,200 m² per container); BIM-coordinated assembly sequence included with every order

Manufacturer: ISO-Certified, Vertically Integrated Steel Building Manufacturer — 23 Years Exporting to 50+ Countries

We are not a trading company or broker. We own and operate nine manufacturing subsidiaries across Hebei Province — including dedicated cold-room panel lines, CNC steel fabrication centers, and automated powder-coating facilities — all under one ISO 9001/14001/45001 management system.

• Full traceability: Every beam carries a QR-coded heat lot number linked to mill test reports (ASTM A653/A792), weld logs, and third-party NDT records
• No supply chain surprises: 92% of raw materials sourced in-house (steel coils, EPS/rock wool cores, fasteners); lead time fixed at 35 days ±3 — guaranteed in contract
• Global compliance embedded: CE-marked structures (EN 1090-1 EXC2), CSA-certified connections, and AISC-approved welding procedures — all verified by BV and SGS prior to shipment
• Real-time production visibility: Clients receive biweekly progress photos, QC checklists, and live ERP updates via shared portal — no “black box” manufacturing
