When Should You Use Extra Wide 90mm Anti-Slip Decking Strips?
Partager
Anti-slip decking strips are a practical way to improve grip on wooden decking, steps, ramps, and walkways. Standard 50mm strips suit many domestic areas, but some surfaces need wider coverage.
Extra-wide 90mm anti-slip decking strips are designed for situations where more surface coverage, stronger visual presence, and improved underfoot grip are important.
If you are still weighing up your options, our guide on how to make wooden decking non-slip compares strips, coatings, tape, and replacement boards.
What Are Extra-Wide 90mm Anti-Slip Decking Strips?
These are wider GRP strips designed to be fixed onto timber or suitable composite decking boards. GRP stands for Glass Reinforced Plastic. The surface has a tough anti-slip grit finish to help provide extra grip in wet, damp, frosty, or shaded outdoor areas.
Compared with narrower strips, 90mm strips cover more of the decking board surface. On a typical timber decking board, a 90mm strip covers a large proportion of the walking surface, which leaves less untreated timber exposed underfoot. This can be useful where a larger textured contact area or a more visible anti-slip strip is preferred.
Standard 50mm vs Extra-Wide 90mm Strips
| Feature | 50mm strips | 90mm strips |
|---|---|---|
| Coverage | Standard | Wider |
| Best for | General decking | Wider boards, ramps, steps, and high-use areas |
| Appearance | More discreet | More visible |
| Grip area | Narrower | Larger |
For many standard boards, our standard GRP decking strips may be enough. For wider boards, steps, ramps, or areas where extra coverage is preferred, 90mm extra-wide strips may be a better option.
When Should You Choose 90mm Strips?
- Wider decking boards
- Outdoor ramps or sloped decking
- Decking steps
- High-traffic areas
- Shaded or damp decking
- Public-access walkways
- Commercial outdoor areas
- Areas used by children, older people, or visitors
- Decking where stronger visual contrast is helpful
Are They Suitable for Steps and Ramps?
If your main concern is the step edge itself rather than the tread surface, a stair nosing may suit better. See our guide to GRP stair nosing and when to use it, or browse the GRP stair nosing range.
Can They Be Used on Composite Decking?
GRP strips can usually be fitted to timber and many composite boards, provided the surface is suitable and the correct fixings are used. For hollow boards or unusual profiles, check the board manufacturer’s fixing guidance first.
How to Install 90mm Decking Strips
- Clean the decking and allow it to dry.
- Position the strips where extra grip is needed.
- Mark the fixing points and pre-drill if required.
- Screw the strips securely into place.
- Check that all edges are flat and not raised.
Do not fit strips onto rotten, unstable, or badly damaged boards. Follow the product guidance and wear suitable PPE when cutting or drilling GRP.
Frequently Asked Questions
Are 90mm strips better than 50mm strips?
Not always. Standard strips suit many areas. 90mm strips are useful when you want wider grip coverage, stronger visibility, or more coverage on ramps, steps, wider boards, or high-traffic areas.
Do I need 90mm strips for every board?
No. Some customers use them only on steps, ramps, entrances, or heavily used areas.
Are they suitable for garden decking?
Yes. They can suit garden decking where wider coverage is preferred, especially in shaded, wet, or frequently used areas.
