As a pioneer in composite material solutions, Nanjing Spare is reshaping the bridge construction industry with its high-performance FRP (Fiber Reinforced Polymer) hollow slabs. Engineered for durability, efficiency and adaptability, these slabs address the core pain points of traditional bridge materials, becoming the preferred choice for modern infrastructure projects worldwide.
The FRP hollow slabs of Nanjing Spare boast exceptional performance driven by innovative structure and premium materials. Their hollow design achieves an optimal balance between light weight and high strength—weighing only 20% to 40% of traditional concrete slabs while maintaining a load-bearing capacity of over 500 kg/m². Crafted from high-quality E-glass fiber and vinyl ester resin, they exhibit outstanding corrosion resistance, withstanding chloride erosion in coastal areas, deicing salts in cold regions and humid environments without rusting or degradation. Thanks to external fiber winding technology, the slabs avoid interlayer peeling and improve transverse mechanical properties, ensuring stable performance under 10⁶ fatigue loads. Additionally, their excellent insulation and anti-magnetic properties eliminate electromagnetic interference risks, ideal for bridges near power facilities.
Customization is a core competitiveness of Nanjing Spare's FRP hollow slabs, tailored to diverse bridge design needs. Our engineering team optimizes structural parameters, including slab thickness, hollow ratio and fiber layering angles, to match specific load requirements and span conditions. For heritage bridge renovation, we customize shapes to preserve historical aesthetics while enhancing load capacity. For coastal bridges, we upgrade resin formulas to strengthen salt corrosion resistance. The slabs can also be integrated with anti-slip gritted surfaces and colored finishes, balancing safety and landscape coordination. Supported by advanced molding and pultrusion processes, we ensure consistent precision for both small-batch and mass production.
Nanjing Spare's FRP hollow slabs find wide applications across bridge construction scenarios. In pedestrian suspension bridges, their lightweight feature reduces stress on cables and towers, as demonstrated in a Yunnan eco-tourism project where 80-meter-span bridges were installed efficiently without heavy machinery. For highway and urban bridges, they serve as main girders and deck slabs, cutting construction time and foundation costs by reducing self-weight. In heritage bridge renovation, they reinforce ancient structures while retaining original styles, such as a Zhejiang historical stone bridge project. They also excel in coastal and marine bridges, resisting seawater erosion to extend service life to over 50 years, far exceeding concrete's lifespan.
Nanjing Spare's FRP hollow slabs blend environmental friendliness, durability and flexibility, aligning with sustainable infrastructure trends. With superior performance and tailored solutions, we empower global clients to build safer, more efficient and low-maintenance bridges.
