Product Introduction
German-style Steel Support is a professional temporary structural support component tailored for construction projects. It provides stable and reliable lateral or vertical support for deep foundation pits, tunnels and large-scale structural construction. Its core role is to prevent soil collapse and structural deformation, thus ensuring construction safety and controlling the deformation of surrounding environments. The product is composed of standardized steel pipes, sections or composite components, which are connected into a complete support system via bolts or welding. It is widely applied in subway projects, deep foundation pits of high-rise buildings, bridges and pipe galleries, with outstanding characteristics of strong load-bearing capacity, high rigidity, quick installation and disassembly, and reusable performance.
Product Advantage
The product adopts Q355B and above high-strength steel and optimizes the structure through finite element analysis. The design axial compression bearing capacity of a single φ609 standard support pipe can reach over 2500kN. Combined with patented flexible joint and pre-applied axial force technology, it can effectively control foundation pit deformation and protect the safety of surrounding buildings.
It realizes 100% standardized and modular design, with strong component interchangeability. The bolted quick coupling improves installation efficiency by more than 60% compared with traditional welding. A set of support system can be reused 8 to 12 times on average, significantly reducing the comprehensive project cost.
It is equipped with an integrated axial force automatic monitoring system with a real-time accuracy of ±1%. Data can be remotely monitored through the Internet of Things platform. When the axial force change exceeds the warning value of ±10%, an automatic alarm will be triggered. Matching with the servo hydraulic system, it can realize dynamic compensation and adjustment of supporting axial force.
All products adopt CNC plasma precise blanking and beveling processing, with end flatness error ≤1mm. They strictly comply with standards such as JGJ120 Technical Code for Foundation Pit Support of Buildings. Each batch of products is provided with material inspection reports, and 100% flaw detection testing is carried out on key welds.
The standardized design reduces the material loss rate to less than 3%, basically achieving on-site zero waste. The product provides full-cycle services from foundation pit design consultation to dismantling and recycling. For special projects, it can customize supports with specifications ranging from φ300 to φ1200mm and composite sections to meet complex geological requirements.
Technical Parameters
The adjustable length range of the German-style steel support covers multiple specifications, including 1400-2700mm, 1600-2700mm, 1620-2640mm, 2000-3500mm, 2200-4000mm and 3000-5500mm. The external pipe diameter is 60.3mm and the inner pipe diameter is 48.3mm, with a wall thickness range of 1.6-4.0mm. Its surface treatment options include spraying, powder spraying, electro-galvanizing and hot-dip galvanizing. For projects with special requirements, the product also supports customized production of non-standard specifications.

FAQ
Under proper use and maintenance, standard products can be safely turned over 8 to 12 times. After each recycling, the components will undergo flaw detection, straightening and anti-corrosion treatment to ensure their mechanical properties meet the requirements of the next use, and a professional test report will be provided.
The key is to apply precise pre-axial force and carry out real-time monitoring. The system integrates high-precision axial force sensors and connects data to the network, realizing 24-hour dynamic monitoring and over-limit early warning, and keeping the deformation within the design allowable range.
The steel support system has high flexibility. Through various combination methods such as longitudinal and transverse bracing, corner bracing and eccentric arrangement, combined with adjustable-length flexible heads, it can meet the support requirements of most irregular foundation pits.
The installation and disassembly efficiency is high. With standardized components and bolted connection technology, the installation of a standard section can usually be completed within a few hours. The disassembly efficiency is higher, and the components can be directly transported to the next construction site, significantly saving construction time.
