GTTW-25(40) TruGrid FRP Pultruded Grating, 25 mm, 40% Open

The GTTW-25(40) is a TRUGRID® FRP (fibreglass) pultruded grating with 25.4 mm (1 in) high I-shaped bearing bars and a 40% open area. TW is the TruGrid bearing bar series, 25 is the bar height and (40) is the open area in percent. The bars are locked by pultruded cross ties and bonded, giving a flush top.

The 40% open grating has the closest bar spacing, so small tools and heels do not drop through and the bars share load more evenly. The 25 mm depth suits walkways and covers on closely spaced supports. Mui Fatt supplies TruGrid grating cut to your layout.

Why FRP

No rust: pultruded glass fibre (up to 70% glass) in polyester or vinyl ester resin does not corrode in wet, salty or chemical areas.
Light: a fraction of the weight of steel grating, so panels are carried and fitted by hand.
Non-conductive: safe near electrical equipment and cable routes.
Easy to cut: panels are cut on site with ordinary power tools; seal cut edges with the resin supplied.

Where It Is Used

Walkways and platforms in water and wastewater plants
Chemical, oil and gas plants
Offshore and coastal access ramps
Trench covers and cooling tower access
