Key Features

Bullnose Rounded Profile

The smooth, rounded leading edge wraps neatly over the front of the stair tread, providing a clean transition between the nosing and the riser below. This profile is particularly suited to staircases where a refined, architectural finish is required.

Double Insert Channel

Two parallel insert channels run the full length of the nosing, accommodating exterior-grade PVC anti-slip strips. The dual-channel configuration increases the effective slip-resistant surface area across the tread edge.

Exterior-Grade PVC Inserts

The inserts are formulated for exterior performance, retaining their grip and dimensional stability in wet, cold, and UV-exposed conditions. They are equally effective indoors, making this nosing a genuinely dual-purpose solution.

3.5mm Gauge Aluminium Body

The 3.5mm wall thickness provides a robust, rigid profile that resists deformation under foot traffic and trolley loads, while remaining light enough for straightforward single-person installation.

Five Premium Finishes

Choose from Mill Finish, Satin Gold, Dark Bronze, Satin Black, or Mirrorflect Gold to complement the surrounding interior scheme. Each finish is applied to the aluminium extrusion for a consistent, long-lasting appearance.

Three Stock Lengths

Available in 2.44 m, 2.75 m, and 3.22 m lengths to suit a wide range of stair widths. All lengths can be cut to size on site without specialist tooling, reducing installation time and material waste.

Typical Applications

  • Commercial office buildings and corporate reception staircases
  • Schools, colleges, and university buildings
  • Apartment blocks, housing developments, and communal stairwells
  • Hotels, restaurants, and hospitality venues
  • Retail units, shopping centres, and public-access buildings
  • External steps, entrance staircases, and covered walkways
  • Refurbishment projects requiring a neat, durable stair edge finish

Insert Selection Guide

Three exterior-grip insert colours are available to suit different aesthetic and visibility requirements. Brimstone (a warm yellow tone) offers high contrast against dark floor coverings and is a popular choice where enhanced visual definition of the stair edge is a priority. Coal (a deep charcoal) provides a discreet, understated finish that blends with darker aluminium profiles and neutral floor tones. Everest (a light grey-white) works well against mid-tone and light-coloured floor coverings, offering a clean, contemporary appearance. All three insert colours are manufactured from the same exterior-grade PVC compound and deliver equivalent anti-slip performance.

Frequently Asked Questions

What is a bullnose stair nosing and where is it used?
A bullnose stair nosing has a rounded, curved leading edge that wraps over the front of the stair tread. It is used on staircases where the tread itself has a rounded or bullnose front edge, providing a neat, flush finish. This profile is common in commercial buildings, apartment blocks, schools, and hospitality venues where both appearance and safety are important.
What does “double channel” mean on a stair nosing?
Double channel refers to the number of grooves (channels) machined into the top face of the nosing to hold the anti-slip inserts. A double channel nosing has two parallel insert channels running along its length, which increases the slip-resistant surface area compared to a single channel profile. This makes it particularly suitable for higher-traffic staircases or locations where additional grip is required.
Are the PVC inserts suitable for outdoor or exterior use?
Yes. The inserts supplied with this nosing are exterior-grade PVC, meaning they are formulated to perform in outdoor conditions including wet weather, low temperatures, and prolonged UV exposure. They retain their anti-slip properties and dimensional stability in exterior environments, making this nosing suitable for external steps, entrance staircases, and covered walkways as well as internal applications.
What floor coverings is this stair nosing compatible with?
This nosing is designed for use with vinyl, linoleum, and lightweight carpet floor coverings. The 3.5mm gauge profile and channel dimensions are optimised for these thinner floor covering types. It is not recommended for use with thick or heavy-pile carpet, timber, or tile without first confirming compatibility with the specific floor covering thickness.
Can the nosing be cut to a custom length on site?
Yes. All three stock lengths (2.44 m, 2.75 m, and 3.22 m) can be cut to the required stair width on site using a standard mitre saw, hacksaw, or aluminium-rated circular saw blade. No specialist tooling is required. It is recommended to cut from one end only to maintain a factory-finished edge at the visible end of the nosing.
How is this stair nosing fixed to the stair tread?
The nosing is fixed using a mechanical screw-down method. Pre-drilled or site-drilled fixing holes are made through the base of the profile, and the nosing is secured to the stair substrate using appropriate screws and plugs for the substrate type (concrete, timber, or steel). Adhesive fixing alone is not recommended for this profile. Always follow current building regulations and the substrate manufacturer’s guidance when selecting fixings.
This double channel bullnose aluminium stair nosing is available to order in your choice of finish, insert colour, and stock length. All lengths are supplied ready to cut and fix, with no additional preparation required. For project quantities or bespoke length requirements, please contact us directly before placing your order.
