High-Quality Q355 Q235 Steel Frame Building with 40-50 Years Lifespan and Multi-Span Design
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 a popular choice for diverse urban and commercial needs.
| Application Fields | Offices, shopping malls, hotels, apartments, mixed-use buildings, hospitals, schools, and government buildings |
|---|---|
| Floor System | Floor deck + concrete |
| Frame Type | Steel light Frame |
| Design Parameters | Wind Load, Snow Load, and Earthquake resistance |
| External Enclosure System | Sandwich Panel for thermal insulation, fireproofing, and soundproofing |
| Frame Life Span | 40-50 years |
- Main Frame: H-section steel beams and columns with spans ranging from 6-9m
- Panel Cover System: Complete waterproof system with metal membrane covering
- Floor System: Concrete + floor deck (0.8-1.2mm thickness, 50-75mm wave height)
- Accessories: Doors, windows, ventilation, light bands, and more
- High Strength-to-Weight Ratio: Lighter yet robust frameworks reduce foundation loads
- Design Flexibility: Enables open floor plans and creative architectural features
- Rapid Construction: Prefabricated components shorten build times by 20-40%
- Durability & Resilience: Resists environmental wear, fire, and seismic activity
- Sustainability: 100% recyclable material with reduced waste
| Dimension | Length x width x Eave height, roof slope |
|---|---|
| Foundation | Concrete and steel foundation bolts |
| Column and Beam | Hot rolled or welded H steel Q355B, high strength bolts connection |
| Bracing | X or V type bracing made from angle steel or steel pipe |
| Purlin | Q235B C/Z section steel with size C160-300 or Z160-300 |
| Surface Treatment | Painting or hot dip galvanized |
- Load-Bearing Capacity: Calculated for vertical and lateral forces
- Fire Safety: Intumescent coatings to meet building codes
- Corrosion Protection: Coatings or galvanization for humid environments
- Vibration Control: Critical for hospitals and labs with heavy machinery
- System Integration: Coordination with utilities and facade systems
We deploy extensive quality control measures including inspections of all materials prior to and following fabrication. Our highly trained fabrication and welding staff deliver services designed to meet your specific project requirements.
- Measuring, cutting and welding the steel
- Precise placement of holes and cleats
- Careful packaging and loading sequence
- Optional on-site erection services
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.
- Professional design team, we could design the drawing as your requirement or calculate the steel quantity based on your drawing.
- Skilled fabrication team and advanced equipment. We make the independent production schedule to each project.
- One-stop service: We have completed lots such kinds of projects, we could provide the integrated proposal for your project.
- Professional QC team will guarantee that we will provide the production and service as your request.
- After sales service: If it has any questions that need us to do in your process of using, such as the maintain of outside insulation and steel components, just tell us, we will try to provide the service as well as we can.
