Detailed Product Description

High Strength Multi Storey Steel Structure Building For Commercial Residential Use

Product Overview

Multi-story steel structure buildings (3-20+ floors) utilize steel as the primary structural framework, offering strength, efficiency, and design flexibility for diverse urban and commercial applications.

Key Performance Traits
  • High Strength & Durability: Withstands heavy loads and harsh weather conditions (winds, snow, rain) without deformation. Corrosion-resistant with 45+ year service life.
  • Large Span & Flexible Space: Supports 20-30 meter column-free spans, maximizing usable area and allowing easy layout reconfiguration.
  • Quick Construction: Prefabricated components reduce construction time by 30-50% compared to concrete structures.
  • Cost-Efficiency: Lower labor costs, minimal maintenance, and good resale value with potential for disassembly/relocation.
  • Sustainability: 100% recyclable materials with energy-efficient insulation options available.
Technical Specifications
Dimension: Custom length × width × height
Foundation: Concrete with steel foundation bolts
Column and Beam: Hot rolled/welded H steel Q355B with high strength bolts connection
Bracing: X/V type bracing from angle steel or steel pipe
Purlin: Q235B C/Z section steel (C160-300 or Z160-300)
Roof/Wall Panel: Corrugated steel sheet or sandwich panel with rock wool/glass wool/PU insulation
Surface Treatment: Painting or hot dip galvanized
Construction Considerations
  • Load-Bearing Capacity: Engineered for vertical loads (flooring, furniture) and lateral forces (wind, earthquakes)
  • Fire Safety: Fireproofing materials integrated to meet building codes
  • Corrosion Protection: Specialized coatings for humid/coastal environments
  • Vibration Control: Designed for minimal vibration in sensitive areas
  • System Integration: Coordinated with utilities and facade systems
Quality Control

Our quality control measures include material inspections before and after fabrication, with trained staff ensuring:

  • Precision measuring, cutting and welding
  • Accurate hole and cleat placement
  • Proper packaging and loading sequence
  • Optional on-site erection services
Packing & Loading:

All the structure components, panels,bolts and sort of accessories will bewell 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.
