GTSL-38(67) TruGrid FRP Pultruded Grating, 38 mm, 67% Open
GTSL-38(67) TruGrid FRP pultruded grating with 38 mm slim bearing bars at 30.5 mm centres, 67% open area and 17.6 kg/m2. Rust-free, non-conductive, for walkways and platforms.
GTSL-38(67) TruGrid FRP Pultruded Grating, 38 mm, 67% Open
The GTSL-38(67) is a TruGrid FRP (fiberglass) pultruded grating with 38 mm high slim bearing bars. "SL" means slim bar and "(67)" means 67% open area. The bars sit at 30.5 mm centres with cross ties every 152.4 mm, and the grating weighs only 17.6 kg/m2, so panels are light to handle and install. It does not rust, does not conduct electricity and resists chemicals, so it suits walkways, platforms and trench covers in wet or corrosive plants.

Questions About This Grating
What does GTSL-38(67) mean?
GT is TruGrid grating, SL is the slim bearing bar, 38 is the bar height in mm and 67 is the open area in percent.
Which resin should I choose?
Grey isophthalic for general use, yellow fire retardant isophthalic where fire rating matters, and green vinyl ester for strong chemicals.
Is it safe to walk on when wet?
Choose the gritted version (GTSL(G)), which has an anti-slip quartz surface bonded on top of the bars.
