Bullnose Aluminium Stair Nosing 35 x 45mm Anti-Slip Step Edge Trim

35 x 45mm Bullnose Aluminium Stair Nosing

This 35 x 45mm bullnose aluminium stair nosing is built to protect the leading edge of stair treads while giving a clean, rounded finish that improves both safety and appearance. The bullnose profile eliminates sharp corners at the step edge, reducing the risk of chipping, cracking and injury, while the anodised aluminium construction ensures long-term resistance to corrosion and heavy footfall.

With a 35mm tread coverage and 45mm riser depth, this profile is well suited to a wide range of stair types. Available in five finishes — Silver, Gold, Champagne, Inox and Black — it integrates cleanly with most interior styles from modern minimalist to traditional domestic.

Compatible Floor Finishes

This bullnose nosing works well on wood, laminate, vinyl, carpet and tiled staircases. It is equally at home in domestic properties and light commercial settings such as offices, retail spaces and hospitality environments.

Installation

Fitted using a standard screw-fix method. Mark and drill pilot holes through the pre-drilled channels in the aluminium profile, plug and screw into the stair tread, and the nosing sits flush and secure. The rounded bullnose profile means there are no exposed edges to catch or snag once installed.

Frequently Asked Questions

What is a bullnose stair nosing?

A bullnose stair nosing has a rounded front edge that curves over the lip of the stair tread. This gives a softer profile compared to a straight-edge nosing, reduces sharp corners at the step edge, and provides a smooth transition that is comfortable underfoot and visually clean.

What floor types does this suit?

This nosing is compatible with wood, laminate, vinyl, carpet and tiled stairs. It is suitable for both residential and light commercial use, and for indoor or sheltered outdoor steps.

How is it fixed to the stair?

Using standard screws into pre-drilled holes in the aluminium profile. Mark positions, drill pilot holes, plug if fixing into masonry or concrete, and screw down. The profile sits flat once fixed and the rounded front edge requires no additional finishing.

Can it be cut to a custom length?

Yes — cut the aluminium with a metal cutting saw or angle grinder fitted with a metal disc. The 1m length suits most standard stair widths; the 2m length can be cut to provide two shorter pieces.
