Application Scenarios
Pultruded Grating T-3815 is suitable for platforms, walkways, trench covers and operating surfaces that require both load-bearing capacity and corrosion resistance. It is commonly used in chemical, water treatment, power and marine engineering applications where corrosive media or humid environments are present. If you need to confirm its suitability under specific media, temperature or load conditions, please contact us to discuss your operating details.
Selection Guidance
This product is assembled with pultruded "I" and "T" profiles as load-bearing bars and solid tubes or rods as connecting rods. When selecting, we recommend considering the load-bearing span, service environment and resin system (such as OFR, IFR, VEFR or phenolic) comprehensively. Different resin types offer different flame retardant and corrosion resistance performance. Please provide your operating conditions, and we will assist in recommending a suitable configuration.
Product Advantages
Compared with traditional metal grating, pultruded grating features light weight, high strength, corrosion resistance and low maintenance. It resists rusting during long-term use and is easy to cut and install on site. Its longitudinal load-bearing bar structure gives the panel good load-bearing capacity in the span direction, making it suitable for locations requiring frequent maintenance access or long-term exposure to corrosive environments.
