Prefab Building Steel Structure Strong Beam Frame Large Span Construction For Factory Warehouse
Steel Structure Buildings
Steel structure buildings utilize steel as the primary load-bearing material, forming stable structural systems through welding, bolting, and other connection methods with components like section steel, steel plates, and beams. Key characteristics include high strength, lightweight properties, and modular construction, making them widely applicable in industrial plants, warehouses, public facilities, and high-rise buildings.
1. Structural Components and Material Characteristics
Primary Components
Load-bearing systems consist of hot-rolled angle steel, channel steel, I-beams, H-beams, steel pipes, and steel plates fabricated into beams, columns, and trusses.
Connection Methods
Welding or high-strength bolted connections ensure structural stability and disassembly flexibility.
Surface Treatment
Anti-corrosion and rust-removal processes enhance durability, supplemented by fire-resistant coatings for safety.
2. Core Advantages
Superior Mechanical Properties
High strength-to-weight ratio (≈50% lighter than concrete structures) reduces foundation costs and improves seismic/wind resistance.
Efficient Construction
Factory prefabrication and on-site assembly shorten construction periods by 30–50%, unaffected by seasonal constraints.
High Space Utilization
Large-span designs minimize internal columns, increasing usable space by ~4% compared to traditional structures.
Sustainability
100% recyclable materials and low construction waste align with low-carbon requirements.
3. Primary Classifications
Based on structural forms and load-bearing mechanisms:
Portal Frame Structures
Ideal for industrial plants and warehouses, featuring clear load paths and standardized components.
Space Truss Structures
Three-dimensional load-bearing systems for large-span public buildings (e.g., stadiums, exhibition halls).
String Beam Structures
Hybrid rigid-flexible systems for ultra-long-span projects like airport terminals.
Multi-Story Frame Structures
Economical and seismic-resistant solutions for buildings under 20–30 floors.
4. Typical Applications
Industrial Sector: Factories and warehouses (spans >30m, 20–30% cost savings vs. traditional structures).
Temporary Buildings: Labor camps and modular shelters requiring rapid assembly/disassembly.
Public Infrastructure: Airports, stadiums, and commercial centers demanding large interior spaces.
