The global prefabricated construction industry is undergoing rapid transformation in 2026, driven by the global push for industrialized building, sustainable construction practices, and urgent demand for faster project delivery. As the core reinforcement component for modern precast concrete structures, lattice girder (also known as steel bar truss, Kaiser Truss, High Chair, Wire Spacers, Continuous High Chairs) has become an indispensable material for precast manufacturers worldwide. According to the latest industry research, the global lattice girder market size is projected to reach $8.7 billion in 2026, growing at a compound annual growth rate of 7.2% from 2022 to 2026.
Lattice girder is a triangular space load-bearing skeleton formed by welding upper chord bars, lower chord bars and corrugated web bars through automated resistance spot welding technology. Our factory produces high-quality lattice girders using premium steel materials including HRB400, HRB500 and CRB600H high-strength steel, with a complete range of specifications: truss heights from 60mm to 300mm, upper chord diameters 4mm-12mm, lower chord diameters 4mm-12mm, and web bar diameters 4mm-7mm. Our products comply with GB, CE and BS international standards, making them suitable for global markets.
Compared with traditional on-site steel bar binding, prefabricated lattice girders offer unparalleled comprehensive advantages. They reduce on-site reinforcement work by 60%-70%, eliminate complex manual binding processes, and allow multi-floor simultaneous construction, shortening overall project timelines by more than 30%. The scientifically designed triangular structure provides excellent mechanical performance: upper chords bear compression, lower chords bear tension, and web bars resist shear, significantly improving the bending resistance, crack resistance and rigidity of concrete components. During construction, lattice girders also serve as high chairs to accurately control concrete cover thickness, provide sufficient rigidity to reduce or eliminate temporary supports (unspanned span up to 5m), and can be used as lifting points for precast components. In composite structures, they act as shear keys across the interface between old and new concrete, enhancing overall structural integrity and preventing delamination.
As a leading professional lattice girder manufacturer based in Tianjin, China, we specialize exclusively in the production of high-standard pure steel bar trusses for precast concrete industry clients worldwide. We operate 4 fully automated production lines with an annual output capacity of 2.5 million square meters equivalent, ensuring stable and timely delivery for both small-batch customized orders and large-scale bulk projects. We support full customization of truss specifications according to specific project requirements, including special heights, bar diameters and lengths.
Our products are widely used in the production of filigran slabs, half-slabs, composite precast floors, double walls, roof panels, wall panels, as well as in bridge, tunnel and foundation pit support projects. We adhere to the business philosophy of quality first and customer-centricity, providing factory-direct prices without intermediaries to help our clients reduce procurement costs. Our experienced engineering team offers comprehensive technical support throughout the entire cooperation process, from product design matching to on-site installation guidance. Whether you are a precast concrete manufacturer, construction contractor or engineering company, we can provide you with reliable, cost-effective lattice girder solutions tailored to your project needs.
