Anti-Slip GRP Decking Strips – Non-Slip Grip Strips for Decking, Steps & Walkways

Turn slippery, weathered decking into a safe, confident walking surface with our Anti-Slip GRP Decking Strips — heavy-duty, gritted safety strips engineered to grip in the wettest, iciest UK conditions.

Made from robust Glass-Reinforced Plastic (GRP) with a resin-bonded gritted surface, each strip is corrosion- and fungus-resistant, won't rot, twist or warp, and is built for a long service life outdoors or indoors. The low-profile 4mm design sits flush enough for wheelchair and pushchair use, while the tough grit delivers dependable underfoot traction in both wet and dry conditions — ideal for garden decking, timber steps, walkways, ramps, jetties, marinas, boat decks, caravan access ramps, and commercial or school walkways.

Why choose our decking strips?

• Full size range — choose 50mm or 90mm widths and 1m or 3m lengths to suit any step or deck board
• Three colourways — Black, Beige or Yellow, so you can blend in with your decking or maximise visibility as a hazard-warning strip
• Simple DIY installation — fix with screws or a suitable exterior-grade adhesive; strips can be cut to length with a hacksaw for a precise fit
• All-weather performance — resists water, oil, mould and UV fading, so grip levels stay consistent all year round
• Low maintenance — clean with a stiff brush or hose down; no recoating or resurfacing ever needed

Where to use anti-slip decking strips

Garden decking, timber and concrete steps, boat decks and pontoons, caravan ramps, fire escapes, school and leisure-centre walkways, warehouse ramps, and anywhere a hard-wearing, slip-resistant edge is needed.

Size & colour guide

Every width and length in our range is available in all three colours — so whatever your project, there's a size that fits.

Installation tips

Ensure the substrate is clean, dry and free from loose debris before fitting. Pre-drilled strips can be screwed directly into timber decking; for smooth or non-timber surfaces, bond with a suitable weatherproof adhesive around the strip's perimeter. Allow strips to acclimatise to outdoor temperature before fitting in cold weather.
