Description
Double Channel Aluminium Stair Nosing — 3.22m Stock Length
A precision-engineered, square-edge aluminium stair nosing profile supplied in a 3.22m stock length, fitted with dual-channel 3.5mm PVC anti-slip inserts. Designed to protect step leading edges, improve underfoot safety, and deliver a clean, professional finish on commercial, public, and residential staircases.
Product Overview
This double-channel stair nosing is a robust, square-profile aluminium extrusion engineered for long-term performance on high-traffic staircases. The profile houses two parallel PVC insert channels, each accepting a 3.5mm gauge insert, creating a clearly defined, slip-resistant tread edge that meets the demands of both commercial installations and domestic refurbishments.
Suitable for use over vinyl, linoleum, and lightweight carpet floor coverings, this nosing is equally at home in offices, schools, retail environments, care homes, and residential properties. Available in six anodised and coated aluminium finishes and fifteen insert colours, it offers exceptional scope for coordinating with existing interior schemes while maintaining a premium, understated aesthetic.

Key Features & Benefits
Double-channel design provides two independent anti-slip insert strips for enhanced tread visibility and grip across the full step width.
3.5mm PVC inserts offer a firm, resilient surface that withstands sustained foot traffic without compressing or lifting.
Square edge profile sits flush and neatly against the step riser, creating a clean, professional finish with no exposed raw edges.
3.22m stock length reduces the number of joins required on longer stair runs, improving both aesthetics and structural integrity.
Six aluminium finishes — from understated Mill Finish to striking Mirrorflect Gold — allow precise coordination with interior design schemes.
Fifteen insert colour options include high-visibility Hazard Yellow and subtle neutrals, supporting both safety compliance and design flexibility.
Lightweight yet rigid aluminium construction resists corrosion, impact, and deformation under load.
Compatible with vinyl, lino, and lightweight carpet floor coverings, making it suitable for a wide range of stair refurbishment projects.
Countersunk fixing holes allow secure, low-profile mechanical fixing directly to the stair substrate.
Typical Applications
This double channel stair nosing is specified across a broad range of environments where step edge protection, slip resistance, and a professional finish are required. Common applications include:
Commercial office buildings and multi-storey workplaces with high daily footfall.
Educational facilities including schools, colleges, and universities.
Retail environments, shopping centres, and hospitality venues.
Healthcare settings such as hospitals, clinics, and care homes where safety is paramount.
Public sector buildings including libraries, civic centres, and transport hubs.
Residential properties undergoing stair refurbishment or new-build fit-out.
Staircases finished with vinyl sheet, linoleum, or lightweight carpet floor coverings.
Insert Selection Guidance
The 3.5mm PVC inserts supplied with this profile are available in fifteen colours to suit both functional and aesthetic requirements. For environments where step edge visibility is a priority — such as care homes, schools, or public staircases — high-contrast options such as Hazard Yellow, Red, or White against a dark aluminium finish provide clear visual differentiation between tread and riser.
For commercial interiors where a more refined appearance is preferred, neutral tones such as Mid Grey, Premium Black, Beige, or Sahara integrate seamlessly with contemporary flooring schemes. The insert sits securely within the machined channel and can be replaced independently of the aluminium body if required, extending the serviceable life of the installation.
Frequently Asked Questions
What does “double channel” mean on a stair nosing?
A double channel stair nosing has two parallel grooves machined into the top face of the aluminium profile. Each groove accepts a separate PVC insert strip, resulting in two lines of anti-slip material running across the tread edge. This increases the slip-resistant surface area compared to a single-channel profile and improves the visual definition of the step edge.
What does the 3.5mm gauge refer to?
The 3.5mm gauge refers to the thickness of the PVC insert that fits into each channel of the aluminium profile. This measurement determines which insert type is compatible with the profile. It is important to match the insert gauge to the channel depth when ordering replacement inserts or specifying the nosing for a project.
Is this stair nosing suitable for carpet stairs?
Yes. This profile is designed for use with vinyl, linoleum, and lightweight carpet floor coverings. It is a surface-mounted nosing that sits on top of the step edge and is mechanically fixed through countersunk holes into the stair substrate. It is not recommended for use with thick or heavily padded carpet, as the profile requires a flat, firm substrate for a secure and level installation.
Can this nosing be cut to a shorter length on site?
Yes. The 3.22m aluminium extrusion can be cut to the required width using a fine-toothed metal cutting blade or mitre saw. This makes the stock length suitable for a wide range of stair widths. Always measure the stair tread width carefully before cutting and deburr any cut edges to ensure a clean, safe finish.
How is this stair nosing fixed to the step?
This nosing is surface-mounted and secured using countersunk screws driven through pre-drilled or site-drilled fixing holes in the base of the aluminium profile. It is suitable for fixing to concrete, timber, steel, and screed substrates. The appropriate screw type and fixing centres will depend on the substrate material and the specific site conditions.
Are replacement PVC inserts available separately?
Yes. The 3.5mm PVC inserts are available as a separate purchase, allowing you to replace worn or damaged inserts without removing the aluminium body from the stair. This extends the working life of the installation and allows insert colours to be updated if the interior scheme changes. Ensure you specify the correct gauge (3.5mm) and channel width when ordering replacements.
