Multi-Story Steel Frame Building Details
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 needs.
Dimension: Customizable length × width × eave height with various roof slopes
Column & Beam: Hot rolled or welded H steel Q355B with high strength bolt connections
Bracing: X or V type bracing made from angle steel or steel pipe
Purlin: Q235B C/Z section steel (C160-300 or Z160-300)
Panels: Single colorful corrugated steel sheet or sandwich panels with EPS, rock wool, glass wool, or PU insulation
Accessories: Skylight belts, ventilators, down pipes, gutters, doors, windows
Surface Treatment: Painting or hot dip galvanized
Packaging: Nude or packed on steel pallet in 40'HQ/OT containers
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 fireproofed), and seismic activity
Sustainability: 100% recyclable material with reduced waste and energy-efficient upgrade potential
Quality Assurance
We implement rigorous quality control measures throughout the project lifecycle:
Material inspections before and after fabrication
Precision measuring, cutting, and welding
Accurate hole and cleat placement
Careful packaging and sequential loading
Optional on-site erection services
