Anti-Slip Stair Nosings for Timber, Composite & Outdoor Steps
RetroGrip® aluminium anti-slip stair nosings improve grip, increase step edge visibility and help make slippery outdoor steps safer without replacing the existing staircase.
Anti-Slip Stair Nosing for Safer Outdoor Steps
RetroGrip® Stair Nosing provides a highly visible anti-slip leading edge for external steps, decking stairs, timber stairways and access routes. Manufactured from durable aluminium with a bonded aggregate anti-slip surface, the nosing helps reduce slip risk in wet, icy and contaminated conditions.
This retrofit stair nosing is suitable for domestic, commercial and public environments where outdoor steps need improved grip, clearer step edge definition and a more slip-resistant walking surface.
The nosings can be bonded to suitable surfaces using a good quality external-grade specialist adhesive, such as Flexy Fix, where appropriate. Mechanical screw fixing can also be used where required, depending on the substrate, exposure, traffic levels and project specification.
Is RetroGrip® Stair Nosing Right for Your Steps?
RetroGrip® Stair Nosing is designed for suitable existing steps where the structure is sound but improved grip and edge visibility are required. It is not intended to repair loose, rotten, broken or structurally unsafe steps.
| Usually Suitable | Check First |
|---|---|
| Outdoor timber steps and decking stairs | Rotten, loose or unstable timber must be repaired or replaced first |
| Composite steps and many external step surfaces | Substrate must be clean, dry, sound and suitable for fixing |
| Garden steps, public access steps and commercial stairways | High-use areas may require mechanical fixing as well as adhesive |
| Steps needing clearer edge visibility and additional grip | Uneven or damaged step edges should be assessed before installation |
How to Make Outdoor Steps Safer
Outdoor steps can become slippery due to rain, frost, algae, moss, shade, leaf debris and worn step edges. Anti-slip stair nosings help by adding a durable grip surface at the leading edge of the step, while also making the step edge easier to see.
For decking stairs, garden steps, external timber steps and commercial access routes, a retrofit aluminium stair nosing can be a practical way to improve safety without replacing the full step structure.
