Application scenarios
Pultruded grating T-1810 is suitable for industrial platforms, walkways, stair treads, trench covers, and applications in wastewater treatment, chemical processing, marine engineering, and similar fields where load-bearing and corrosion resistance are required. Its structure is assembled from pultruded "I"- or "T"-shaped load-bearing bars with solid tubes or rods as connecting rods, offering light weight, high strength, corrosion resistance, and slip resistance. Please consult us regarding specific applicable environments based on your operating conditions.
Selection guide
When selecting, consider the resin type (such as orthophthalic, isophthalic, vinyl ester, or phenolic) to meet different corrosion resistance and flame-retardant requirements, and determine the grating thickness, opening (grid) size, load rating, and surface anti-slip treatment. Different resin systems correspond to different chemical resistance and flame-retardant performance; for example, phenolic resin offers low toxicity and high flame retardancy. Please contact us for detailed specifications and selection recommendations.
Product advantages
Pultruded grating T-1810 is formed by the pultrusion process, with high fiber content, offering excellent unidirectional strength and high stiffness. Compared with molded grating, pultruded grating provides higher strength in the load-bearing direction and is suitable for long-span applications. The product is corrosion resistant, maintenance-free, insulating, non-magnetic, and easy to install. Please consult us for specific performance parameters.

Operating environment
- Pultruded FRP grating T-1810 is suitable for indoor and outdoor use in industrial plants, wastewater treatment facilities, chemical processing areas, and offshore platforms.
- The pultruded FRP load-bearing bars and connecting rods resist moisture, humidity, and attack by a variety of highly corrosive chemical media, making the grating suitable for exposed and washdown environments.
- When a flame-retardant resin system (such as phenolic or vinyl ester resin) is used, the grating can be used in areas with fire safety and low toxicity requirements.
- For detailed recommendations on resin selection and environmental limits for your specific site conditions, please contact us.
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.
