Application Scenarios
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 where damp, acid, alkali or salt spray environments exist. If your operating conditions involve high temperatures, severe corrosion or special loads, please contact us to confirm a suitable solution based on the specific media, 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. Since different resin and fiber ratios affect strength, flame retardancy and corrosion resistance, please contact us with your operating parameters and we will assist you in completing the 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 retained in the panel surface, thus combining 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.
