Application Scenarios
Pultruded Grating I-40125 is assembled from pultruded I-shaped load-bearing bars and solid tubes or rods as connecting rods, making it suitable for platforms, walkways, trench covers and various industrial operating surfaces that require both load-bearing capacity and corrosion resistance. Its open-gap structure facilitates drainage, chip removal and ventilation, and it is commonly used in humid or corrosive environments such as chemical, electroplating, water treatment and marine engineering. If you need to confirm suitability for your specific working conditions, please contact us.
Selection Guide
Selection can be judged by combining the resin system with the service environment: the phenolic type offers outstanding flame retardancy and is suitable for occasions with high fire safety requirements; the vinyl type performs well in corrosion resistance and is suitable for most acid and alkali media environments. The spacing of load-bearing bars, the form of connecting rods and the overall thickness directly affect load-bearing and stiffness performance. Please contact us for detailed specifications and selection advice.
Product Advantages
The pultrusion process arranges fibers continuously along the load-bearing direction, giving the grating high longitudinal strength and stiffness, while also possessing the common features of FRP materials: lightweight, corrosion-resistant, non-conductive and maintenance-free. The surface can be treated for anti-slip, and it is easy to install and cut, making it suitable to replace metal grating in corrosive environments. Specific performance is subject to actual specifications; please contact us to confirm.
