GTSL-25(67) TruGrid FRP Pultruded Grating, 25 mm, 67% Open
GTSL-25(67) TruGrid FRP pultruded grating with 25 mm slim bearing bars at 30.5 mm centres, 67% open area and 13.2 kg/m2. Standard panel 3 x 18 ft. Rust-free and non-conductive.
GTSL-25(67) TruGrid FRP Pultruded Grating, 25 mm, 67% Open
The GTSL-25(67) is a TRUGRID® FRP (fibreglass) pultruded grating with 25 mm high slim bearing bars and a 67% open area. The bars sit at 30.5 mm centres with cross ties every 152.4 mm, and the grating weighs only 13.2 kg/m².
SL means slim bar. The high open area lets water, light and air through, and the light weight makes it easy to handle. It is the shallower partner of the GTSL-38(67).

Values from the TRUGRID catalogue, for design selection. 6.35 mm (1/4 in) deflection is the usual limit for walking comfort. For a 5 kN/m² walkway load, keep the span to about 1,067 mm or less.
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
Questions and Answers
What does GTSL-25(67) mean?
GT is TruGrid grating, SL is the slim bearing bar, 25 is the bar height in mm and 67 is the open area in percent.
GTSL-25 or GTSL-38?
Both have the same bar spacing. The 38 mm bar spans much further, so choose it when supports are more than about 1 m apart.
How many clips do I need?
14 SS316 clips per 3 x 18 ft panel, about 4 per 3 x 3 ft, depending on the supports underneath.
Is it slippery when wet?
Choose the gritted GTSL(G), with quartz grit bonded on the bars.
