Detailed Specifications
1. Structural Safety
- Seismic & Wind Resistance: Buckling-Restrained Braces (BRBs) and flexible frames dissipate seismic energy; wind tunnel tests validate load distribution
- Dynamic Load Design: Simulate crane loads (e.g., 50t overhead cranes) and stacking loads per GB 50009-2012, ensuring joint fatigue life≥50 years
- Fire & Corrosion Protection: Intumescent coatings (fire resistance≥2h) and hot-dip galvanizing + epoxy coatings for harsh environments
2. Material Selection
- Main Steel: Q355B steel (tensile strength 470-630MPa) for primary structures; cold-formed steel (1.5-3mm thickness) for lightweight needs
- Envelope System: Polyurethane panels (thermal conductivity≤0.024W/m*K) with rock wool insulation (density≥100kg/m³)
- Eco-Materials: Recycled steel (recovery rate≥30%) and solvent-free epoxy flooring (VOC≤50g/L) reduce carbon footprint
3. Prefab Component Design
- Large-Span Modularization: 40m-span trusses or space frames maximize storage space (clear height≥10m)
- Standardized Joints: Predefined joint catalogs (e.g., rigid beam-column connections) cut welding time by 25%
- Transportation & Assembly: Segments≤15m with temporary bracing; on-site assembly error≤3mm
4. Energy Efficiency
- Passive Design: Skylights (≥20% coverage) and smart louvers reduce HVAC energy use by 40%
- Renewable Energy: Monocrystalline PV panels (≥300kW*h/day) and ground-source heat pumps cover 30%+ energy demand
- Resource Recycling: Bolted connections and precast foundations enable 95%+ material recovery at end-of-life
5. Construction Quality Control
- Factory Prefabrication: Laser cutting (±1mm) and robotic welding (99%) ensure component consistency
- On-Site Management: BIM + 3D scanning monitors installation; column verticality≤H/1000, beam≤L/1500
- Acceptance Standards: Per GB 50205-2020: Welds: UT≥40%, MT full coverage; Bolts: 100% torque inspection, preload error≤±10%
Product Applications
Our pre-engineered steel buildings are ideal for:
- Industrial warehouses and storage facilities
- Manufacturing plants and workshops
- Agricultural buildings and hangars
- Commercial showrooms and retail spaces
An efficiently designed pre-engineered building can be lighter than conventional steel buildings by up to 30%, resulting in material savings and reduced structural costs.
