Installation Notes

This nosing is supplied as a full 3.22 m (3220 mm) stock length and is intended to be cut to the required tread width on site using a fine-tooth metal saw or mitre saw. Fix mechanically through the countersunk holes in the base of the profile using appropriate fixings for the substrate — masonry anchors for concrete, wood screws for timber, or self-tapping screws for steel. PVC inserts are pressed into the channels after fixing and can be replaced independently if worn. Ensure the step surface is clean, level, and free from debris before installation. For best results on carpet-covered stairs, trim the carpet flush with the riser face before fitting.

Frequently Asked Questions

What does "double channel" mean on a stair nosing?
Double channel refers to the two parallel recessed grooves machined into the top face of the nosing profile. Each channel holds a PVC slip-resistant insert. Having two channels side by side increases the total anti-slip surface area across the tread, providing greater grip underfoot compared to a single-channel profile.
What floor coverings is this nosing compatible with?
This profile is designed for use with vinyl, linoleum (lino), and lightweight carpet. The 84 mm tread width and 37 mm riser height are sized to accommodate these softer floor coverings neatly at the step edge. It is not recommended for heavy-duty carpet or thick rubber flooring, for which a deeper or wider profile would be more appropriate.
Can I cut the 3.22 m length to fit my stair width?
Yes. The 3.22 m stock length is supplied specifically so it can be cut to the exact tread width required on site. A fine-tooth metal-cutting saw or mitre saw is recommended for a clean, accurate cut. One length will typically cover multiple steps on a standard domestic or commercial staircase.
How is the nosing fixed to the step?
The profile is fixed mechanically using countersunk screws through pre-formed fixing holes in the base of the aluminium section. The appropriate fixing type depends on the substrate: masonry anchors for concrete steps, wood screws for timber, and self-tapping screws for steel. No adhesive is required, though a compatible sealant can be used in addition for extra security in wet environments.
Can the PVC inserts be replaced once fitted?
Yes. The PVC inserts are pressed into the channels and can be removed and replaced independently without disturbing the aluminium base profile. This makes maintenance straightforward — if an insert becomes worn or damaged over time, it can be swapped out quickly without the need to remove and refit the entire nosing.
Which aluminium finish should I choose?
The right finish depends on your interior scheme and budget. Mill Finish is the most cost-effective option and suits utilitarian or industrial settings. Bright Polished offers a classic, reflective look suited to traditional interiors. Satin Black and Dark Bronze work well in contemporary or hospitality environments. Satin Gold and Mirrorflect Gold are premium decorative finishes ideal for high-specification or luxury projects where the nosing is a visible design feature.
