Product Introduction
Italian-style Steel Support is a professional temporary structural component designed for large-scale construction projects such as deep foundation pits, tunnels, high-rise building foundations, and pipe galleries. Its core function is to provide stable lateral and vertical supporting forces, effectively preventing soil collapse and structural deformation, and thus ensuring construction safety. Composed of standardized steel pipes, sections or composite components, this product is assembled into an integrated support system via bolts or welding. It is characterized by strong load-bearing capacity, high rigidity, quick installation and disassembly, and repeated reuse, making it a key support solution for underground and large-scale construction projects that require strict deformation control of the surrounding environment.
Product Advantage
Made of Q355B and above high-strength steel, the product’s structure is optimized 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 precisely control foundation pit deformation and protect the safety of adjacent buildings.
The product adopts 100% standardized and modular design, with highly interchangeable components. The bolted quick coupling connection mode improves installation efficiency by more than 60% compared with traditional welding methods. Each set of support system can be reused 8–12 times under proper maintenance, which significantly reduces the comprehensive construction cost.
Equipped with an integrated axial force automatic monitoring system, the product has a real-time monitoring accuracy of ±1%. The monitoring data can be remotely transmitted and viewed through the Internet of Things platform. When the axial force change exceeds the warning value of ±10%, the system will trigger an automatic alarm. Matching with the servo hydraulic system, it can realize dynamic compensation and adjustment of supporting axial force.
All products in the series are processed by CNC plasma precise blanking and beveling, with the end flatness error ≤1mm. The production strictly complies with the requirements of Technical Code for Foundation Pit Support of Buildings (JGJ120). Each batch of products is provided with material inspection reports, and 100% flaw detection testing is carried out on key welds to ensure stable product quality.
The standardized design reduces the material loss rate to less than 3%, basically achieving zero waste on the construction site. We provide full-cycle services covering foundation pit design consultation, installation guidance, dismantling and recycling. For special geological projects, we can customize supports with specifications ranging from φ300 to φ1200mm and composite sections to meet diverse construction needs.
Technical Parameters
The Italian-style Steel Support has a flexible adjustable length range, covering four main specifications from 1600–2900mm to 2200–4000mm. Its external pipe diameter is uniformly set to 56mm, and the inner pipe diameter is 48mm, with the wall thickness of 1.5–2.75mm. For surface treatment, the product offers multiple options including spraying, powder spraying, electro-galvanizing and hot-dip galvanizing to meet different anti-corrosion requirements of construction environments. In addition to the standard specifications, we also support customized production of non-standard parameters according to the actual needs of customers.

FAQ
Under proper use and regular maintenance, the standard Italian-style Steel Support can be safely reused 8–12 times. After each recycling, we will conduct flaw detection, straightening and anti-corrosion treatment on all components, and issue a professional test report to ensure that their mechanical properties fully meet the requirements of the next use.
The key to controlling foundation pit deformation is precise pre-applied axial force and real-time monitoring. Our support system is integrated with high-precision axial force sensors, which can realize 24-hour dynamic monitoring and over-limit early warning through the IoT platform, ensuring that the foundation pit deformation is always within the design allowable range.
Yes. The Italian-style Steel Support system has excellent flexibility. By adopting various combination methods such as longitudinal and transverse bracing, corner bracing and eccentric arrangement, and matching with adjustable-length flexible heads, it can meet the support requirements of most irregular foundation pits.
The installation and dismantling are highly efficient. With standardized components and bolted quick connection technology, the installation of a standard section can be completed within a few hours. The dismantling speed is faster, and the components can be directly transported to the next construction site after dismantling, which greatly saves the overall construction period.
