Heavy Wind Resistance Steel Structure Building Concrete Steel Mixed Building
Product Overview
Multi-story steel structure buildings are high-rise or mid-rise structures (typically 3-20+ floors) using steel as the primary structural framework. They combine strength, efficiency, and design flexibility, making them ideal for diverse urban and commercial applications.
Application Fields
| Application |
| Offices, shopping malls, hotels, apartments, mixed-use buildings, hospitals, schools, and government buildings |
Structural Components
- Main Frame: H-section steel beams and columns with spans of 6-9m
- Floor System: Concrete + floor deck (0.8-1.2mm thickness, 50-75mm wave height)
- Materials: Steel bars (bearing and distribution bars), concrete (C30-C40)
Key Performance Advantages
- High Strength-to-Weight Ratio: Lighter yet robust frameworks reduce foundation loads while supporting multiple floors
- Design Flexibility: Enables open floor plans, large spans, and creative architectural features
- Rapid Construction: Prefabricated components shorten build times by 20-40% compared to concrete
- Durability & Resilience: Resists environmental wear, fire (when protected), and seismic activity
- Sustainability: 100% recyclable material with reduced waste and energy-efficient upgrade potential

Construction Considerations
- Load-Bearing Capacity: Calculated for vertical and lateral forces
- Fire Safety: Intumescent coatings meet building codes
- Corrosion Protection: Coatings or galvanization for humid/coastal areas
- Vibration Control: Dampers for sensitive environments
- System Integration: Coordinated with utilities and facade systems
Quality Control
Our quality control measures include material inspections before and after fabrication, with certified welding and fabrication processes:
- Precision measuring, cutting, and welding
- Accurate hole and cleat placement
- Careful packaging and loading sequence
- Optional on-site erection services
Packing & Loading
All the structure components, panels, bolts and sort of accessories will be well packed with standard package suitable ocean transportation and loaded into 40'HQ.
All the products are loaded at the loading site of our factory using crane and forklift by our skilled workers, who will prevent the goods to be damaged.
