Product Introduction
Galvanized Steel Support Series are professional temporary structural components designed to ensure construction safety in deep foundation pits, tunnels, and large-scale structural projects. Their primary function is to provide stable lateral and vertical support forces, preventing soil collapse and structural deformation. Composed of standardized steel pipes, profiles, or composite components connected via bolts or welding, these supports are characterized by high load-bearing capacity, excellent rigidity, quick installation and disassembly, and repeated usability. Widely applied in subway construction, high-rise building deep foundation pits, bridges, and pipe galleries, they are a key measure to control surrounding environmental deformation and ensure underground and large-scale construction safety.
Product Advantage
Manufactured with Q355B and higher-grade high-strength steel, the supports are optimized via finite element analysis. A single φ609 standard support pipe achieves a design axial compression bearing capacity of over 2500kN. Combined with patented flexible joints and pre-applied axial force technology, the system effectively controls foundation pit deformation and protects surrounding buildings. Key keywords: Q355B high-strength steel support, 2500kN load-bearing support pipe, foundation pit deformation control system.
The supports adopt a fully standardized modular design, ensuring strong component interchangeability. Bolted quick couplings boost installation efficiency by over 60% compared to traditional welding methods. Under proper maintenance, a single set of support systems can be reused 8 to 12 times, significantly cutting project comprehensive costs. Key keywords: modular standard steel support, bolted quick installation system, 12-time turnover support component.
Integrated with an automatic axial force monitoring system, the supports deliver real-time monitoring accuracy of ±1%. Data is transmitted to an IoT platform for remote tracking, and automatic alarms are triggered when axial force changes exceed the ±10% warning threshold. Combined with a servo hydraulic system, the supports realize dynamic compensation and adjustment of supporting axial force. Key keywords: automatic axial force monitoring steel support, IoT intelligent support system, servo hydraulic compensation support.
All products in the series undergo CNC plasma precision blanking and beveling, with an end flatness error ≤1mm. Production strictly follows standards such as the Technical Code for Foundation Pit Support of Buildings (JGJ120). Each batch is accompanied by material inspection reports, and 100% flaw detection testing is conducted on key welds to ensure product quality. Key keywords: CNC precision machining support, JGJ120 standard support component, 100% weld flaw detection steel support.
Standardized design reduces material loss rates to below 3%, achieving nearly zero on-site waste. We provide full-cycle services from foundation pit design consultation to dismantling and recycling. For special projects, we offer customized supports with specifications ranging from φ300mm to φ1200mm and composite profiles to meet complex geological conditions. Key keywords: low-loss green steel support, full-cycle support solution, large-diameter customized foundation pit support.
Technical Parameters
The Galvanized Steel Support Series mainly includes adjustable steel props, designed for projecting scaffolding and internal scaffolding erection as building scaffold components. Surface treatment options cover painting, powder coating, electro-galvanizing, and hot-dip galvanizing (HDG). The maximum support height is flexible, with options including 3m, 3.2m, 3.6m, 4m, 4.5m, and 5m. Nut types are available as cup nuts or cast nuts, and the minimum order quantity (MOQ) is 500 pieces. The supports come in multiple types: Spanish Type, Italian Type, and Middle East Type, with a single row scaffolding lapping form. Steel grades used are Q195 and Q235, and tube thickness ranges from 1.5-2.5mm to 1.5-3.5mm. Base plate options include square plates, flower base plates, and U-heads, while pin types cover G pins, line pins, and wire pins. Transportation packages are available as loose packing, steel strip bundling, or pallet packing.

FAQ
Under proper use and maintenance, standard supports can be safely reused 8 to 12 times. After each recycling, components undergo flaw detection, straightening, and anti-corrosion treatment. We provide test reports to confirm that their mechanical properties meet reuse requirements.
The key is precise pre-axial force application and real-time monitoring. Our system integrates high-precision axial force sensors, enabling 24-hour dynamic monitoring and over-limit early warning via IoT connectivity, keeping deformation within the design allowable range.
The steel support system has high flexibility. Through combination methods such as longitudinal bracing, transverse bracing, corner bracing, and eccentric arrangement, paired with adjustable-length flexible heads, it meets the support needs of most irregular foundation pits.
Installation is highly efficient. With standardized components and bolted connection technology, a standard support section can be installed within a few hours. Dismantling is even faster, and components can be immediately transported to the next construction site, significantly saving construction time.
