FRP Pultruded Grating - I or T Bearing Bars for High Load

FRP pultruded grating, also called GRP pultruded grating, is made of glass fiber and polyester resin surface similar to FRP molded grating. It adopts I or T bars as the bearing bars and round or shaped bars as connecting rod and assemble them together in a certain process. Compared with FRP molded grating, it can supply higher load capacity and high strength to weight ratio. It is ideal for installing places where exceptional loading bearing and uninterrupted spans needs to be bridged.

Advantages of FRP pultruded grating

  • Super strength. The FRP pultruded grating has high loading capacity to withstand the heavy duty applications.
  • Lightweight. It is much lighter structure than the steel grating and FRP molded grating.
  • Anti-slip performance. Grit, convex, corrugated surface supply excellent slip resistance performance for people's security.
  • Corrosion resistance. The FRP pultruded grating has excellent chemical and physical corrosion resistance. It will never corrode during its long service life.
  • Flame retardant. Same as the FRP molded grating, the pultruded grating have a flame spread rating of 25 or less, as tested in accordance with ASTM E-84 and meets the self-extinguishing requirements of ASTM D-635.
  • Maintenance free. The FRP pultruded grating has excellent self-cleaning performance. It needs little maintenance during using period.
  • High strength to weight ratio. Less than half the weight of steel grating, allowing easy installing and replacing.
  • UV protection. The polyester resin surface has excellent UV resistance protection. It can protect FRP pultruded grating from UV rays and extend the service life of grating.
