The global construction industry is accelerating its transformation toward circular economy and modular construction in 2026, and detachable floor slabs, as the core component of reusable building systems, are experiencing explosive growth. Traditional one-time floor systems generate massive construction waste, while detachable floor slabs realize the circular utilization of building materials through modular design and industrialized production, becoming an important direction for the development of green buildings. As the core load-bearing and connecting component of detachable floor slabs, lattice girder (also known as steel bar truss, Kaiser Truss, High Chair, Wire Spacers, Continuous High Chairs) has become the key to promoting the popularization of this technology with its excellent mechanical properties and prefabrication advantages. According to industry forecasts, the global detachable floor slab market will grow at a compound annual growth rate of 11.5% from 2026 to 2030, driven by the strong demand for temporary buildings, modular housing and transformable commercial spaces worldwide.
Detachable floor slabs are usually composed of precast concrete units, lattice girder load-bearing systems, quick-connect nodes and support systems. Among them, the lattice girder adopts a scientifically designed triangular space force-bearing structure, consisting of one upper chord bar, two lower chord bars and corrugated web bars, which are connected by factory automated resistance spot welding technology. This structure not only provides sufficient bending and shear strength for the floor slab, but also serves as a lifting point and temporary support, greatly simplifying the installation and disassembly processes. We produce high-quality lattice girders using premium steel materials including HRB400, HRB500 and CRB600H high-strength steel, with a complete range of specifications covering truss heights from 60mm to 300mm, upper chord diameters 4mm-12mm, lower chord diameters 4mm-12mm, and web bar diameters 4mm-7mm. All products comply with GB, CE and BS international standards, and can be perfectly adapted to the design requirements of various detachable floor slab systems, including filigran slab based reusable floors, lattice girder slab detachable systems, half-slab modular units, composite precast floor system integrated solutions, wide slab flooring for large-span projects and double wall precast integrated floor-wall systems.
Compared with traditional cast-in-place floor slabs and ordinary precast floor slabs, detachable floor slabs with lattice girders have outstanding comprehensive advantages. They can reduce on-site reinforcement work by 60%-70%, eliminate complex manual binding processes, and shorten the overall construction cycle by more than 30%. More importantly, these floor slabs can be reused 5-10 times after disassembly, significantly reducing the full life cycle cost of buildings and cutting construction waste by more than 80%. The factory-prefabricated lattice girders ensure precise control of reinforcement spacing and concrete cover thickness, with errors controlled within ±1mm, which significantly improves the structural stability and durability of the floor slabs. During the construction phase, lattice girders also serve as high chairs to accurately control the concrete cover thickness, provide sufficient rigidity to reduce temporary supports with an unsupported span of up to 5 meters, and can be directly used as lifting points for precast units, further enhancing construction efficiency and safety. For Girder-Slab certified fabricators, our lattice girders are fully compatible with the patented Girder-Slab system, providing reliable core reinforcement for steel beam-precast slab composite structures.
Current detachable floor slab technology is developing toward standardization, integration and intelligence. The industry is establishing unified standards for component sizes and connection nodes to achieve universal interchangeability of products from different manufacturers. At the same time, integrating water and electricity pipelines, insulation layers and other functional components into floor slab units further reduces on-site operations. In addition, the application of digital technology enables full-process traceability of the design, production, installation and recycling of detachable floor slabs, improving management efficiency and reducing error rates. As a core component supplier, we have 4 fully automated production lines with an annual output capacity of 2.5 million square meters equivalent, which can provide both standardized and customized lattice girder products to meet the needs of detachable floor slab projects of different scales, from small modular residential units to large-span industrial wide slab flooring projects.
Our technical team, composed of experienced structural engineers, can provide targeted truss specification matching solutions according to the project’s load requirements, span conditions and reuse times, helping customers optimize the structural design and cost control of detachable floor slabs. Our lattice girders are widely used in various detachable building systems including filigran slab-based reusable floors, half-slab detachable systems, double wall integrated floors and Girder-Slab system compatible solutions, and have been verified in numerous temporary exhibition halls, modular residential projects, transformable commercial buildings and large-span industrial plants.
