Finishes & Insert Colours
Architectural Finishes
Exterior Grip Insert Colours
Exterior Grip inserts are formulated for outdoor and high-moisture environments, retaining their slip-resistant properties in wet conditions, at entrances, and on steps exposed to the elements.
Key Features & Benefits
Double Insert Channels — Two parallel grip channels deliver greater slip resistance and stronger visual contrast across the stair tread, improving both safety and wayfinding.
Exterior-Grade Grip Inserts — Specially formulated PVC inserts perform reliably in outdoor, wet, and high-moisture environments, making this nosing equally at home on external steps and entrance staircases.
Durable Aluminium Alloy Profile — The 3.5 mm gauge aluminium construction resists impact, wear, and deformation under sustained foot traffic, protecting both the step edge and adjacent floor coverings.
Long Stock Lengths — Available in 2.44 m, 2.75 m, and 3.22 m lengths to span most stair widths in a single run, reducing joints and delivering a cleaner, more professional installation.
Six Architectural Finishes — From understated Mill Finish to striking Mirrorflect Gold, the range of finishes allows the nosing to complement or contrast with any interior or exterior design scheme.
Easy Maintenance — The aluminium profile and PVC inserts are straightforward to clean and maintain, retaining their appearance and grip performance over the long term.

Insert Selection Guidance
All insert colours in this listing are Exterior Grip — a high-performance PVC formulation suited to outdoor steps, entrance areas, and any location subject to moisture, dirt, or temperature variation. Choose your insert colour to achieve the desired level of visual contrast against your stair tread:
- Brimstone — A warm, light tone that provides strong contrast on darker stair surfaces
- Coal — A deep, neutral shade that blends with dark treads while maintaining a defined edge
- Everest — A clean, bright tone offering maximum contrast for high-visibility applications
Frequently Asked Questions
What are the dimensions of this stair nosing?
The profile has an 85 mm tread width, a 32 mm riser height, and a 3.5 mm gauge (profile thickness). It is available in three stock lengths: 2.44 m (2440 mm), 2.75 m (2750 mm), and 3.22 m (3220 mm).
Can this stair nosing be used on external or outdoor steps?
Yes. This nosing is fitted with Exterior Grip inserts, which are specifically formulated for outdoor and high-moisture environments. It is suitable for external staircases, entrance steps, and any area exposed to rain or surface water.
What type of stair edge does this nosing require?
This profile is designed for square-edge stairs. It is not suitable for bullnose or rounded step edges. If your stairs have a different profile, please check our full range for a compatible option.
Can the aluminium profile be cut to a custom length?
Yes. The aluminium profile can be cut on-site to your required length using standard metalworking tools. The three stock lengths — 2.44 m, 2.75 m, and 3.22 m — are designed to cover most stair widths with minimal waste and as few joints as possible.
What floor coverings is this stair nosing compatible with?
This nosing is suitable for use with vinyl, lino, and lightweight carpets. Its square-edge, double-channel profile is designed to sit flush against these floor coverings for a neat, secure finish.
How is this stair nosing installed?
Installation is typically carried out using mechanical fixings such as countersunk screws, a suitable construction adhesive, or a combination of both, depending on the substrate and the level of foot traffic expected. The method should be selected based on the stair material and the specific conditions of the installation.
