FRP Grating

Fiber Reinforced Plastic (FRP) grating is a moulded, one piece fiberglass reinforced plastic grating, available in standard panels or fabricated into panels of the shape you require to fit your floor. 

The square pattern design with interwoven construction allows load to be transferred to the adjoining bars providing a superior load-carrying capacity.

The high resin-to-glass ratio provides maximum corrosion resistance to a wide range of chemicals frequently encountered in many industries.

Wellter FRP comes in one standard panel size 1220 x 3660 mm.



1. Integral, one piece construction increases load-bearing capabilities.

2. Load applied to Wellter FRP bar is transferred to adjoining bearing bars, assisting in load distribution on the grating as well as on the     

    support structure.

3. Smooth resin-rich vertical surfaces and tapered bars allow all debris to fall through.

4. Continuous glass fibre strand in alternating layers thoroughly wetted with the appropriate resin for excellent corrosion resistance.

5. Open area 70%.
