FRP Pultruded Grating

Nanjing Spare FRP pultruded grating is a high-performance lightweight structural material made of high-strength glass fiber and corrosion-resistant resin through continuous pultrusion integral molding. Compared with traditional metal gratings, it features light weight, high strength, corrosion resistance, anti-slip, insulation, flame retardancy and zero maintenance. The product has excellent environmental adaptability and structural stability, which can effectively solve the problems of rusting, aging, deformation and frequent maintenance of steel and aluminum gratings in harsh working environments. To meet the diversified load-bearing, environmental and engineering scenario requirements, we divide our FRP pultruded gratings into three categories: Class I General Type, Class II Enhanced Type and Class III Heavy-Duty Type, covering all conventional and high-standard engineering application 

    Class I: General FRP Pultruded Grating

    • Product Features: Class I general grating is designed for conventional light-load and indoor conventional environments. Adopting standard glass fiber and universal anti-aging resin formula, it achieves balanced performance and cost-effectiveness. The product has uniform overall structure, stable size, basic anti-slip and anti-corrosion capabilities, and meets daily safe use standards. It is lightweight and easy to cut, install and transport, with low comprehensive engineering cost.
    • Core Advantages: Cost-effective, stable quality, easy construction, low maintenance
    • Application Scenarios: Indoor walkways, municipal landscape platforms, light-duty trench covers, factory auxiliary passages, civil facility platforms

      Class II: Enhanced FRP Pultruded Grating

        • Product Features: Class II enhanced grating is upgraded on the basis of general type, adopting high-density glass fiber layered reinforcement and high-grade corrosion-resistant resin. It effectively improves structural rigidity, load-bearing performance and environmental resistance. The product adds UV anti-aging and enhanced waterproof and anti-corrosion properties, adapting to long-term outdoor and slightly corrosive working environments. All products pass strict dimensional inspection and load-bearing sampling test to ensure stable long-term operation.
          Core Advantages: Enhanced load-bearing, excellent anti-aging performance, strong corrosion resistance, longer service life
          Application Scenarios: Outdoor factory platforms, sewage treatment workshops, chemical plant auxiliary passages, coastal ordinary facilities, logistics handling walkways

        Class III: Heavy-Duty FRP Pultruded Grating

        • Product Features: Class III heavy-duty grating is our high-spec industrial-grade product, customized for heavy-load and extreme harsh environments. It adopts ultra-high-strength continuous glass fiber and imported flame-retardant anti-corrosion resin, with optimized dense grid structure and integral thickened molding. The product has ultra-high load-bearing capacity, strong impact resistance, and can withstand long-term heavy pressure and frequent rolling. It supports customized flame retardant, anti-static and high weather resistance upgrades, fully complying with international industrial safety standards.
          Core Advantages: Super high strength, heavy-load resistance, extreme corrosion resistance, safety and durability, customizable high-performance parameters
          Application Scenarios: Chemical industrial main platforms, offshore marine engineering, oil field facilities, power plant operation passages, heavy-duty equipment trench covers
