Steel supports for construction are indispensable core load-bearing components in the field of architectural engineering, primarily used in applications such as excavation support, main structural construction, and tunneling. By precisely transferring loads and maintaining structural stability, they provide a solid guarantee for the safety and quality of construction projects. This product is crafted from high-strength steel through precision manufacturing, combining exceptional mechanical performance with outstanding durability, making it suitable for a wide range of complex construction environments.

Product Core Parameter Table

Product Advantages

1. Exceptionally strong load-bearing capacity, safe and reliable

High-grade low-alloy high-strength steel of Q355B grade and above is selected, and the cross-sectional design is optimized through professional mechanical calculations to ensure that the product remains resistant to bending, deformation, or fracture under high-intensity loads. During production, non-destructive testing (UT, MT) is rigorously implemented, with 100% inspection conducted on all critical welds to effectively eliminate internal defects. This approach ensures a safety factor that far exceeds industry standards, providing critical assurance for structural stability throughout the construction process.

2. Precision machining, highly adaptable

Utilizing automated processing equipment such as CNC cutting, precision welding, and CNC turning, the component dimensions are controlled within ±0.3mm, ensuring tight fit at joints and effectively minimizing stress concentrations. We also offer customization options tailored to specific project needs, including cross-sectional dimensions, lengths, connection methods, and surface treatment processes. This flexibility allows the components to seamlessly meet the construction requirements of diverse scenarios—such as foundation pits, tunnels, high-rise buildings, and bridges—while adeptly handling complex and challenging construction environments.

3. Corrosion-resistant and anti-aging, with a long service life

For common corrosive environments in construction—such as humidity, salinity, and dust—a hot-dip galvanizing process or a composite coating system combining "sandblasting for rust removal + epoxy-rich zinc primer + fluorocarbon topcoat" is employed. The hot-dip galvanized layer forms a dense zinc-iron alloy coating that effectively shields the surface from air and moisture. Meanwhile, the composite coating boasts exceptional adhesion and outstanding resistance to aging, making it suitable for extreme temperature conditions ranging from -40°C to 60°C. This advanced coating system ensures an outdoor service life of up to 15 to 20 years, significantly reducing long-term maintenance costs.

4. Easy to disassemble and assemble, efficient construction

Optimize the design of the connection structure: flange connections use standardized high-strength bolts, while pin-joint connections are equipped with a quick-locating device, allowing a single person to easily complete installation and removal using just basic tools. Additionally, the weight of standard section components has been optimized through lightweighting, making them easier to lift and transport on-site. Compared to traditional concrete supports, this approach boosts installation efficiency by more than 60%, significantly reducing construction timelines and substantially lowering labor and equipment costs.

5. Eco-friendly and recyclable

The product is primarily made from recyclable steel, which can be 100% recovered and reused after disposal, significantly reducing material waste and construction debris compared to single-use concrete supports. During production, low-carbon welding technology is employed to minimize energy consumption and pollutant emissions, aligning with the nation’s green building construction standards and environmental protection policies.

Application scenarios

1. Excavation Support Engineering

Suitable for foundation pit support systems in deep excavations, ultra-large pits, and complex geological conditions—such as subway station basins, basement excavations for high-rise buildings, and integrated utility tunnel pits. During the excavation process, steel supports serve as either horizontal or vertical bracing elements, effectively counteracting lateral soil pressure and water pressure against the pit walls, thereby preventing pit collapse and displacement. This ensures the safety of surrounding structures, underground utilities, and construction personnel. In scenarios involving soft soil foundations or sandy geological layers—where deformation is more likely—dynamic support can be achieved by adjusting the axial force of the steel supports, allowing them to adapt flexibly to stress changes during excavation.

2. Main structural construction

Used in scenarios such as formwork support and load-bearing scaffolding during the construction of main structures in high-rise buildings, large-span factory halls, convention centers, and more. During the concrete pouring process for beams, slabs, and columns, steel supports serve as temporary load-bearing components, providing a stable support system that ensures the structural integrity of the concrete throughout the curing phase. This prevents issues like cracking or dimensional deviations in concrete elements caused by support deformation. For large-span spatial structures, high-strength support frameworks can be constructed using modular steel supports, perfectly tailored to meet the complex demands of advanced structural construction.

3. Tunnels and Underground Engineering

Suitable for the initial support and secondary lining construction of highway tunnels, railway tunnels, urban rail transit tunnels, and underground passages. During tunnel excavation, steel supports can be combined with shotcrete, rock bolts, and other elements to form a composite support system, effectively resisting surrounding rock pressure, preventing tunnel collapse and deformation, and ensuring the stability of the tunnel's excavation profile. The product boasts excellent impact resistance, making it well-suited to handle challenging conditions such as blasting vibrations encountered during tunnel construction. Additionally, its lightweight design facilitates easy installation and adjustment even in the confined spaces of tunnels.

4. Bridge Construction Works

Applied in scenarios such as bridge pile foundations, bridge piers, box girders, and suspended formwork construction. During the casting of bridge box girders, steel supports serve as the core components of the suspended formwork's load-bearing structure, effectively transferring the weight of both the formwork and the concrete, thereby ensuring stability throughout the formwork’s movement and the pouring process. In bridge pier construction, these supports can be used as part of the formwork support system, guaranteeing the verticality and dimensional accuracy of the pier concrete placement. With their exceptional high strength and fatigue resistance, these products are perfectly suited to meet the long-term load-bearing and dynamic loading demands inherent in bridge construction projects.

5. Temporary Reinforcement and Emergency Repair Works

Suitable for emergency scenarios such as retrofitting existing buildings, reinforcing dilapidated structures, and post-disaster emergency repairs. When a building’s structural stability declines due to aging, increased loads, or natural disasters, a steel support system can be rapidly installed to provide temporary reinforcement, effectively transferring loads and distributing stress—thereby preventing further damage to the structure. Additionally, the quick-installation and removal features of steel supports help minimize construction time during emergency repairs, buying valuable time for both rescuing personnel and restoring the building’s integrity.
