Q355B Prefabricated Steel Buildings For Warehouse Workshop Application
Prefabricated steel building systems are professionally engineered structures that provide cost-effective and efficient low-rise buildings. All major prefabricated steel building systems require CAD tools to custom design each building system and components according to customers' needs, specifications, and local building codes.
Key Components
The metal building system includes primary rigid frames, secondary members (wall girts and roof purlins), cladding, and bracing. These elements are engineered to function as an integrated system. Primary rigid frames are designed in accordance with steel structure design standards.
Applications
Steel building systems are used in various applications including warehouses, workshops, factories, distribution centers, office buildings, shopping malls, airplane hangars, poultry houses, schools, and government buildings.
Product Specifications
Our prefabricated buildings meet three quality principles:
- Higher strength: Large bearing capacity with smaller sections and lighter weight
- Better plasticity and toughness: Resistant to brittle failure and suitable for dynamic loads
- Excellent machining performance: Good welding ability, cold bending performance, and corrosion resistance
