Applications
Pultruded Grating T-3310 is suitable for platforms, walkways, trench covers, stair treads and equipment operating surfaces that require a combination of load-bearing capacity, corrosion resistance, and ventilation and drainage. It is commonly used in chemical, water treatment, electroplating, marine engineering and power applications involving damp, acid-base or salt-spray environments. If your operating conditions involve high temperatures, severe corrosion or special loads, please contact us to confirm a suitable solution based on the specific medium, span and installation method.
Selection guide
When selecting, we recommend first clarifying the resin system (such as OFR, IFR, VEFR or phenolic types, corresponding to different flame-retardant and corrosion-resistance orientations), the load-bearing direction and the support span, then confirming the grating thickness, mesh spacing and connection method to match the actual load and installation conditions. Because different resin and fiber ratios affect strength, flame retardancy and corrosion resistance, please contact us with your operating parameters and we will assist with selection and specification confirmation. For detailed specifications and quotations, please contact us.
Product advantages
Pultruded Grating T-3310 uses pultruded "I"-shaped and "T"-shaped profiles as load-bearing bars, combined with solid tubes or rods as connecting rods, assembled according to a certain process with gaps left in the panel surface, so it combines relatively high longitudinal load-bearing capacity with light weight, corrosion resistance and ease of cutting and installation. This structure facilitates ventilation, drainage and light transmission, and is non-conductive and non-magnetic, making it suitable as a replacement for some metal gratings in corrosive environments. Specific performance varies with resin and fiber configuration; please contact us to confirm the applicable configuration.
Inquiry prompt

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.
