Installation and accessories
Application scenarios
Pultruded grating T-1215 uses pultruded I-profiles and T-profiles as load-bearing bars, with solid tubes or rods as connecting rods. It is suitable for platforms, walkways, trench covers, stair treads and similar applications that require both load-bearing capacity and corrosion resistance. In humid or corrosive environments such as chemical processing, water treatment, electroplating and marine engineering, it can serve as an alternative to conventional metal grating. To confirm suitability for your specific operating conditions, please contact us with details of your service environment.
Selection guidance
Selection can be considered from several aspects: resin system, load-bearing direction, span and installation method. The resin type must match the corrosiveness and flame-retardant requirements of the environment; the specification and spacing of the load-bearing bars determine the load capacity; and the type of connecting rods affects overall stiffness. Different resin and fiber ratios correspond to different corrosion resistance and flame-retardant performance. We recommend providing the service medium, temperature range and load conditions so that we can help recommend a suitable configuration.
Product advantages
The pultrusion process arranges fibers continuously along the load direction, giving the product high strength and stiffness in the load-bearing direction, along with the common advantages of FRP materials: light weight, corrosion resistance and maintenance-free performance. The grating surface can be made in an anti-slip form, and it is easy to cut and adjust on site during installation. It does not rust easily over long-term use. Compared with molded grating, pultruded grating is better suited to applications with load and span requirements.
Inquiry guidance

Please provide information such as the service environment, load requirements, dimensions and quantity, and we will provide targeted recommendations and commercial terms accordingly.
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.
