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.

• 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

• 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.
