Earthquake Resistant Steel Frame Building For Offices Hospitals Schools Portal Frame

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
• Type: Single/double/multi-slope; single/double/multi-span; single/double/multi-floor configurations
• Foundation: Concrete with steel foundation bolts
• 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

• 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

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

We provide integrated solutions for steel structures including:

• Layout consulting and structural design
• Fabrication and delivery solutions
• Installation guidance and support

Production capacity: 2,500 tons/month in 20,000m² workshop (30,000m² total factory space). We operate complete production lines for H steel, C/Z purlins, and various steel panels.
