Description
Double Channel Aluminium Stair Nosing — 2.44m Stock Length
A square-edge, double channel aluminium stair nosing fitted with 3.5mm gauge PVC slip-resistant inserts. Designed to protect and define stair tread edges in commercial, public, and residential settings, this profile delivers a clean, professional finish with a wide choice of aluminium finishes and insert colours to suit any interior scheme.
About This Product
This double channel stair nosing is a precision-extruded aluminium profile engineered to provide durable edge protection and enhanced slip resistance on stair treads. It is used wherever a clearly defined, safe, and visually contrasting step edge is required — from busy commercial staircases and public buildings to residential apartment blocks and educational facilities.
Supplied in a 2.44 metre (2440mm) stock length, the profile is straightforward to cut on site to the exact stair width required. The double channel configuration accepts two runs of 3.5mm PVC insert side by side, allowing for contrasting colour combinations that improve step visibility and support hazard marking where needed. The aluminium carrier is available in six anodised and coated finishes, with fifteen insert colour options to complement or contrast with surrounding floor coverings.

Insert Selection Guidance
This profile is designed for use with 3.5mm gauge PVC inserts in a double channel configuration. The insert gauge must match the channel depth of the profile to ensure a secure, flush fit. Inserts are available in fifteen colours, allowing you to select a combination that provides clear visual contrast against the surrounding floor covering — an important consideration for step safety and visibility in both well-lit and low-light conditions.
For environments where hazard marking is required, the Hazard insert colour (yellow and black) is recommended for the leading channel. For general commercial use, neutral tones such as Mid Grey, Dark Grey, or Premium Black offer a discreet, professional appearance. Brighter options including Apple Green, Red, and Dark Blue are well suited to educational and leisure environments where colour-coding of routes or zones is beneficial.
Frequently Asked Questions
Q: What is the difference between a single channel and a double channel stair nosing?
A single channel stair nosing has one groove and accepts one PVC insert. A double channel profile has two parallel grooves, allowing two inserts to be fitted side by side. This makes it possible to use two contrasting colours for improved step visibility, hazard marking, or colour-coded routes — which is why the double channel design is widely used in commercial and public buildings.
Q: What are the dimensions of this stair nosing profile?
The tread (horizontal) face is 85mm wide and the riser (vertical) face is 32mm high. The aluminium profile is 3.5mm thick throughout, and the PVC inserts are also 3.5mm gauge to match the channel depth. The stock length supplied is 2.44 metres (2440mm).
Q: What floor coverings is this stair nosing suitable for?
This profile is designed for stair treads finished with vinyl, linoleum (lino), or lightweight carpet. The square-edge profile sits flush against these floor coverings and provides a neat, secure transition at the stair edge. It is not recommended for thick or heavily cushioned carpets.
Q: How is this stair nosing installed?
The profile is screw-fixed through the base of the aluminium carrier directly into the stair tread. Pre-drill countersunk fixing holes at regular intervals along the length before fitting. For extra security — particularly on smooth or non-porous surfaces — apply a suitable contact adhesive beneath the profile before screwing down. Press the PVC inserts into the channels once the aluminium is fixed in place.
Q: Can this profile be cut to size on site?
Yes. The 2.44 metre stock length is designed to be cut on site to match the exact width of each stair tread. Aluminium cuts cleanly with a fine-toothed hacksaw or a mitre saw fitted with an appropriate blade. The PVC inserts can be trimmed separately with a sharp knife or scissors to match the cut length of the profile.
Q: Is this stair nosing suitable for outdoor use?
This profile is intended for interior stair installations. While extruded aluminium resists corrosion, prolonged outdoor exposure — including UV radiation, standing water, and temperature extremes — may affect the PVC inserts over time. For external staircases, a profile specifically rated for outdoor use with UV-stable inserts is recommended.
