Heavy Wind Resistance Steel Structure Building with 40-50 Years Frame Life Span and Hot Rolled H Steel Q355B
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 |
|---|
| Offices, shopping malls, hotels, apartments, mixed-use buildings, hospitals, schools, and government buildings |
- 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)
- 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

- 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
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
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 can design the drawing as your requirement or calculate the steel quantity based on your drawing.
- Skilled fabrication team: Advanced equipment and independent production schedule for each project.
- One-stop service: Integrated proposal for your project based on extensive experience.
- Quality assurance: Professional QC team guarantees production and service meet your requirements.
- After-sales service: Maintenance support for insulation and steel components as needed.
Yes, we welcome factory visits. We can arrange airport pickup from Qingdao Airport and hotel booking services.
Our process includes: 1) Receiving your project details, 2) Providing free design services, 3) Contract signing with 30% deposit, 4) Design confirmation, 5) Production with final payment before shipment, 6) Optional installation services.
Prices vary based on material quality, size, and design complexity, typically ranging from $19 to $100+ per square meter.
We provide detailed construction drawings and manuals. On-site installation services are available with costs covered by the buyer.
Typically 30 days after receiving deposit, with partial shipment available for large orders.
Options include normal anti-rust paint, epoxy zinc primer, hot-dip galvanization, hot-dip galvanization+PU finish, or stainless steel structures.
Our products meet CE EN1090 and ISO9001:2008 standards, with quality inspection reports provided for all materials and processes.
We use premium steel from major mills, smarter designs for safety and economy, durable high-grade materials (lasting 10-20 years), and avoid cost-cutting measures that compromise long-term value.
