Application Scenarios
Pultruded Grating T-3810 is commonly used in industrial platforms, walkways, trench covers, stair treads and equipment operating surfaces that require load-bearing capacity and corrosion resistance. As pultruded profiles are used as load-bearing bars, it is suitable for environments requiring long spans, light weight, high strength and resistance to chemical media, such as chemical, water treatment, electroplating and marine engineering applications. To confirm suitability for specific media and working conditions, please contact us for detailed specifications and selection advice.
Selection Guidance
Selection requires comprehensive consideration of the resin system, grating thickness, load-bearing bar spacing, load-bearing direction and installation support conditions. Different resin types differ in flame retardancy and corrosion resistance, and the matching resin grade should be selected according to the actual environment. We can provide selection references based on your load, span and media conditions. Please contact us to discuss your specific requirements.
Product Advantages
Pultruded grating is assembled with pultruded I/T profiles as load-bearing bars and solid tubes or rods as connecting rods, combining high specific strength, light weight, corrosion resistance and ease of cutting and installation. Compared with traditional metal grating, it is insulating, non-magnetic and low in maintenance cost, making it suitable for long-term exposure to humid or corrosive environments.
