FRP grating is a structural panel made from glass fiber reinforcement and thermosetting resin. It is used in industrial walkways, platforms, and trench covers where corrosion resistance and non-conductivity are needed. The product family includes both molded and pultruded types, each with different manufacturing processes and structural behavior.
What is FRP Grating
FRP grating is produced by embedding continuous glass fibers in a resin matrix. The two main methods—molding and pultrusion—create panels with different strength directions. All FRP grating is non‑magnetic and non‑conductive, and can be supplied with polyester, vinyl ester, or flame‑retardant resin systems. Panel depth, mesh size, and surface finish vary by product line.
Typical Industrial Environments
FRP gratings are commonly used in industries where metal flooring degrades or presents an electrical hazard. These include chemical processing plants, wastewater treatment facilities, marine and offshore platforms, and electrical substations.
Frequently Asked Questions
Can FRP grating be cut on site?
Yes, FRP grating can be cut with standard tools. However, field cutting exposes glass fibers at the cut edges. Proper re‑sealing with a compatible resin coating is required to maintain corrosion resistance at the cut surface.
Is FRP grating non-conductive?
FRP is generally non-conductive, but the electrical properties depend on the specific resin and fiber content. For critical electrical isolation, the product configuration should be evaluated against the required dielectric strength.
