Anti-slip FRP plates for steel grating walkways
Gritted fibreglass plates that bolt onto steel grating from above to mark escape routes, walkway edges and hazards. The grit is cured into the resin, so the marking keeps its grip for the life of the plate instead of wearing off like paint. Fire class Bfl-s1, 316 stainless fixings, no rust.
Edges, turns, landings and escape routes on open grating
Edge strips show where a walkway ends. Full-width plates cover landings, gates and thresholds.
Walkway edges
Continuous strips along both sides keep the route visible in poor light.
Corners and step-outs
Cut to follow the route around valves, columns and equipment.
Landings and thresholds
Full width where the walkway meets a solid deck, a stair or a ladder foot.
Route junctions
Branches and turns stay clear where several routes meet. Use two arrows at a junction, not a split arrow.
Clipped to the grating bars, tightened from the top
Everything is done from above. The nut is welded to the clip, so there is no second person underneath and no second spanner.
Cut and drill
Cut the 1200 mm plate to length with a grinder or jigsaw. Drill Ø8 holes so each one falls over a gap between bearing bars. Or order the plates cut to size with the holes pre-drilled.
Clip under the bar
Drop the 316 stainless saddle clip through the grating and hook it under the bearing bar beneath the hole.
Tighten from the top
Put the M6 bolt and mushroom washer through the plate into the clip's nut. Hand-tight plus a quarter turn.
Use at least two fixings per plate, one every 600 mm or less. A 1200 mm plate takes about five minutes, and the walkway is open as soon as the last bolt is tight. A worn or cracked plate unbolts and is replaced on its own.

Why FRP rather than paint or steel
- Grit that stays putCured into the resin, so there is no top layer to peel or wear off.
- Fire class Bfl-s1Low flame spread and the lowest smoke class on an escape route.
- No rustSalt water, diesel and hydraulic oil don't touch it.
- Non-conductiveGlass fibre and resin carry no current, and it is non-magnetic.
Anti-slip FRP plates, answered
What are anti-slip FRP plates?
Solid 3.0 mm glass-fibre plates with quartz sand and fused alumina grit cured into the resin. They bolt over steel grating or solid floors to mark escape routes and walkway edges and to give a non-slip surface that does not rust.
Can they be fitted to existing grating without welding?
Yes. A 316 stainless saddle clip with a welded nut hooks under the bearing bar, and an M6 bolt is tightened into it from above. Nothing is welded, and one person with one socket fits a 1200 mm plate in about five minutes.
Do they rust offshore?
No. The plate is glass fibre in isophthalic resin, which resists salt water, fuels, oils and dilute acids and alkalis. The clips, bolts and washers are 316 stainless steel.
Are they fire rated?
Yes. The plates are classified Bfl-s1 to EN 13501-1, tested to EN ISO 9239-1 and EN ISO 11925-2: low flame spread and the lowest smoke class, so they add no fire load to an escape route.
Do they glow in the dark?
The photoluminescent version does. It charges under normal lighting and glows green in darkness (200 mcd/m²), so an escape route stays readable after a power failure.
What colours can I get?
Safety yellow (RAL 1023) is standard. Photoluminescent, black, grey, red and white are also available, and colours can be mixed on one order. Arrows, chevrons and text are painted on to your layout, or plates are supplied plain.
Can they be cut to fit?
Yes. The standard plate is 1200 × 100 × 3.0 mm and cuts to any length on site with a grinder or jigsaw. No edge sealing is needed. We can also supply them cut to size with the holes pre-drilled.
What comes with each plate?
Clip sets (saddle clip with welded nut, M6 bolt and mushroom washer) come with every plate, with spares in packs of 20. Test reports, an installation video and a method statement are available on request.
