Fast Assemble Steel Portal Frame Industrial Warehouse Buildings
Steel building systems are professionally engineered structures that provide cost-effective and efficient low-rise buildings. All major steel building systems require CAD tools to custom design each building according to customers' needs, specifications, and local building codes. The system includes primary rigid frames, secondary members (wall girts and roof purlins), cladding, and bracing - all engineered to work as an integrated system.
Applications
Our steel structures are used in diverse applications including production facilities, warehouses, distribution centers, retail stores, shopping centers, automobile dealerships, office complexes, airplane hangars, schools, libraries, churches, medical facilities, and government buildings.
Key Advantages
- Environmentally friendly with 100% recyclable materials
- Lower cost and minimal maintenance requirements
- Fast construction with easy installation
- Attractive appearance with durable finish
- Structural stability with earthquake and wind resistance
- Effective sound insulation properties
