Application scenarios
Pultruded grating T-3810 is commonly used for industrial platforms, walkways, trench covers, stair treads and equipment operating surfaces that require load-bearing capacity and corrosion resistance. Because 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 processing, water treatment, electroplating and marine engineering. To confirm suitability for specific media and operating conditions, please contact us for detailed specifications and selection advice.
Selection guide
Selection should take into account 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 guidance based on your load, span and media conditions; please contact us to discuss your specific requirements.
Product advantages
Pultruded grating is assembled from pultruded I/T profiles as load-bearing bars together with solid tubes or rods as connecting rods, combining high specific strength, light weight, corrosion resistance and ease of cutting and installation. Compared with conventional metal grating, it is insulating, non-magnetic and low in maintenance cost, making it suitable for long-term exposure to damp or corrosive environments. For more details on material composition and structural advantages, please contact us.

For detailed specifications, load parameters, resin options and custom solutions for pultruded grating T-3810, please contact us. Please provide your operating environment, dimensional requirements and load requirements, and we will provide a quotation and technical support accordingly. All commercial terms are subject to the inquiry communication confirmed by both parties.
Operating environment
- Pultruded FRP grating T-3810 is constructed from pultruded "I"-shaped or "T"-shaped profiles as load-bearing bars and solid tubes or rods as connecting rods, and is suitable for indoor and outdoor industrial platforms, walkways and tread boards.
- The vinyl ester resin VEFR-25 used in this grating has an oxygen index of 28 or above, supporting use in damp or mildly corrosive environments with moisture and chemical exposure.
- For fire-safety-critical locations with low-toxicity requirements, the MP-5 phenolic resin option can provide high flame retardancy, making the grating suitable for enclosed or high-risk process areas.
- Please contact us for the complete parameter list to confirm resin selection and configuration according to your specific temperature, humidity and chemical exposure conditions.
Custom Cutting
Need panels that fit, or cut to shape? We custom cut FRP grating and profiles to your drawing: panels cut to size or to shape (corner cuts, cutouts), cut edges sealed with resin, and pre-cut and pre-drilled to drawing before shipping. See the custom cutting services.
