Typical Applications
This double-channel nosing profile is well suited to a broad range of interior staircase environments where edge protection, slip resistance, and a clean finish are all required:
- Office buildings, retail premises, and commercial interiors
- Schools, colleges, universities, and educational facilities
- Hotels, leisure centres, and hospitality venues
- NHS and private healthcare buildings
- Residential properties, apartment blocks, and housing developments
- Public buildings, civic centres, and local authority premises
- Refurbishment and new-build staircase projects
Insert & Flooring Guidance
The PVC inserts are pre-fitted into the two aluminium channels before despatch. No additional adhesive is required to secure the inserts — they are retained by the channel profile under normal use. The 3.5 mm insert thickness is matched to the 3.5 mm gauge of the aluminium body, ensuring a flush, level surface across the full tread.
This profile is designed for use with vinyl sheet, linoleum, and lightweight carpet floor coverings. The square-edge front face sits directly against the riser or the edge of the tread, making it particularly effective where the floor covering terminates at the nosing line. For heavier carpet or specialist flooring types, please refer to the appropriate profile within the wider range.
Frequently Asked Questions
What is a double channel stair nosing and how does it differ from a single channel?
A double channel nosing contains two parallel grooves running along the length of the profile, each filled with a slip-resistant PVC insert. This provides two continuous lines of grip across the tread edge, offering greater slip resistance than a single-channel profile. It is particularly well suited to higher-footfall environments where additional underfoot safety is a priority.
Can this nosing be cut to a shorter length on site?
Yes. The 2.75 m stock length is designed to be cut to size on site using a standard mitre saw or aluminium-rated cutting blade. This allows a single length to be used across multiple steps of varying widths, reducing material waste and simplifying ordering.
Which floor coverings is this nosing compatible with?
This profile is designed for use with vinyl sheet, linoleum (lino), and lightweight carpet. The square-edge profile and 3.5 mm gauge are well matched to the thickness and installation requirements of these floor covering types. It is not recommended for use with heavy-duty or thick-pile carpet, for which a deeper or raked-back profile would be more appropriate.
How is the nosing fixed to the stair tread?
The profile is fixed using countersunk screws through pre-drilled or site-drilled holes in the base of the aluminium channel. Screws are not included and should be selected to suit the substrate — typically timber, concrete, or steel. The screw-fix method provides a secure, permanent installation suitable for both new-build and refurbishment projects.
Can I change the PVC insert colour after installation?
The PVC inserts are supplied pre-fitted and are retained within the aluminium channels by the profile geometry. In most cases the inserts can be removed and replaced with a compatible insert of a different colour if requirements change, though this is best carried out before installation. Please contact us if you require replacement inserts.
Is this nosing suitable for outdoor or wet-area use?
This profile is designed and recommended for interior use only. Aluminium is naturally corrosion-resistant, but the PVC inserts and certain decorative finishes are not specified for prolonged exposure to outdoor conditions, standing water, or direct weathering. For external staircase applications, please refer to profiles within the exterior nosing range.
