Single Channel Aluminium Stair Nosing — 2.44m Stock Length with Interchangeable PVC Insert
This single-channel aluminium stair nosing is a precision-engineered edge-protection profile designed to define, protect, and visually highlight the leading edge of interior stair treads. Supplied in a 2.44 m (2440 mm) stock length with a rake-back underside profile, it is fixed directly to the step front and accepts a replaceable slip-resistant PVC insert. Suitable for use on stairs finished with vinyl, linoleum, or lightweight carpet, it is an established choice for commercial, public-sector, and residential staircases where durability, safety, and a clean finish are equally important.

Installation Note: This nosing is designed for surface fixing to the step tread front. The rake-back underside profile sits flush against the riser face. Fix through the aluminium base using appropriate screws for your substrate, then press the PVC insert into the channel. Cut to length using a fine-tooth metal saw or mitre saw. Always wear appropriate PPE when cutting aluminium profiles.
Frequently Asked Questions
What does "single channel" mean on a stair nosing?
A single-channel stair nosing has one recessed groove running along its length, designed to hold one PVC insert strip. This is the correct choice for stairs covered with a single floor finish such as vinyl, linoleum, or a lightweight carpet, where one continuous insert provides the required slip resistance and step-edge definition.
What is a rake-back profile and do I need it?
A rake-back profile has an angled or stepped underside that allows the nosing to sit flush against the vertical face of the stair riser as well as the horizontal tread. This is the standard requirement for most interior staircases with a square-edge step front. If your steps have a bullnose or rounded edge, a different profile type would be required.
What floor coverings is the 3.5 mm insert gauge suitable for?
The 3.5 mm gauge PVC insert is designed for use with vinyl, linoleum, and lightweight carpet. The insert thickness is matched to the depth of these floor coverings so that the nosing sits level with the finished floor surface. For thicker carpets or other floor finishes, a different gauge or profile may be more appropriate.
Can the PVC insert be replaced without removing the aluminium profile?
Yes. The PVC insert clips into the channel of the aluminium base profile and can be removed and replaced independently. This means that when the insert becomes worn or you wish to change the colour, you do not need to unfix and refit the entire nosing — only the insert needs to be replaced, which significantly reduces maintenance time and cost.
How do I cut the nosing to the correct width for my staircase?
The 2.44 m (2440 mm) stock length can be cut to your required stair width using a fine-tooth metal-cutting saw or a mitre saw fitted with an appropriate blade. Mark your cut line clearly, secure the profile before cutting, and always wear appropriate personal protective equipment including eye protection and gloves when cutting aluminium.
Which insert colour should I choose for maximum step-edge visibility?
For maximum step-edge visibility and compliance with safety and accessibility guidelines, the Hazard and Yellow insert colours provide the strongest contrast against most stair tread finishes. These are commonly specified in public buildings, schools, and healthcare environments. For a more discreet finish that still defines the step edge, Mid Grey, Premium Black, or a colour matched to your floor covering are popular choices.
