Why Decking Grip Strips Matter
Slippery decking is one of the most common outdoor safety issues in the UK. Our wet, cold climate makes wooden and composite decks prone to algae, moss, and water build-up — turning beautiful outdoor spaces into potential hazards.
That’s where decking grip strips come in. These narrow anti-slip inserts provide instant traction and help prevent slips and falls — without changing the look or structure of your deck.
At Finishings UK, we specialise in non-slip decking grip strips, GRP gratings, and stair nosings designed for long-term outdoor performance. In this complete guide, we’ll explain what decking grip strips are, how they work, and why they’re a must-have safety feature for homes and commercial spaces across Britain.
What Are Decking Grip Strips?
Decking grip strips are slim anti-slip covers made from Glass Reinforced Plastic (GRP) or similar non-corrosive materials. They’re installed directly onto the surface of existing decking boards to create a rough, high-traction surface.
Each strip contains a gritted aggregate layer that provides superior grip underfoot — even in rain, frost, or mud. These strips are typically screwed into place using stainless steel fixings and are available in various sizes and colours to match your decking.
✅ Key Features:
-
Made from durable GRP (Glass Reinforced Plastic)
-
Weather-resistant and UV-stable
-
Quick to install — no specialist tools needed
-
Low-maintenance and easy to clean
-
Suitable for both timber and composite decking
How Do Decking Grip Strips Work?
Decking grip strips function by increasing the coefficient of friction between footwear and the decking surface.
The gritted top layer — often made from tough silica or quartz — creates micro-ridges that prevent slipping, even when wet. The underlying GRP base ensures the strip won’t rot, warp, or rust over time.
Because the strips are mechanically fixed with screws rather than adhesives, they can be easily replaced or repositioned — making them ideal for DIY installation or professional projects alike.

1. Slip Resistance in All Weather
GRP decking grip strips remain grippy even in the wettest, iciest, or muddiest conditions. Perfect for UK patios, ramps, steps, and walkways.

Best Decking Grip Strips for Wooden Decking
Not all strips are made equal — especially when it comes to wood.
Wooden decks expand, contract, and absorb moisture differently than composite materials, so choosing the right grip strip is essential for long-term adhesion and safety.

Decking Grip Strips vs GRP Floor Grating
If you’re deciding between grip strips and full GRP floor grating, the key difference lies in coverage and application.
-
Decking Grip Strips are retrofitted safety additions — great for upgrading existing decks.
-
GRP Floor Grating is a complete non-slip flooring solution — often used in industrial or high-traffic areas.
Both are durable, corrosion-resistant, and designed for maximum slip protection.
Why Choose GRP Over Metal or Wood?
GRP (Glass Reinforced Plastic) offers the perfect balance between strength, safety, and longevity.
Unlike metal grating, GRP doesn’t rust or corrode. It’s also lighter to handle, easier to install, and non-conductive — ideal for outdoor, marine, or electrical environments.
