Frequently Asked Questions

What is a stair nosing and why do I need one?
A stair nosing is a protective and safety-enhancing profile fitted to the leading edge of a step. It defines the step edge clearly, reduces the risk of slips and trips, and protects the stair from wear and chipping. On external or high-traffic stairs, a quality aluminium stair nosing with an anti-slip insert is one of the most effective ways to improve stair safety and longevity.
Can this stair nosing be used on fully external, outdoor stairs?
Yes. When specified with Exterior Grip inserts (available in Brimstone, Coal or Everest), this profile is suitable for fully exposed outdoor stairs, including fire escapes, entrance steps and external access stairways. The Exterior Grip insert is engineered to maintain reliable traction in wet, icy and weathered conditions. Ensure installation uses appropriate exterior-grade fixings and sealant.
What stair profile shape is this nosing designed for?
This profile is designed for square-edge stairs — steps where the leading edge meets the riser at a right angle. It is not suitable for bull-nosed or rounded stair edges. If your stairs have a rounded or profiled edge, a different nosing profile would be required.
What floor coverings is this stair nosing compatible with?
This single-channel, 3.5mm gauge profile is suitable for use with vinyl, lino and lightweight carpet floor coverings. The gauge refers to the depth of the channel that accommodates the floor covering at the stair edge. It is not recommended for thicker or heavy-duty carpet types.
Can the stair nosing be cut to size on site?
Yes. The aluminium profile can be cut down from any of the three stock lengths — 2.44m, 2.75m or 3.22m — using appropriate metal-cutting tools such as a mitre saw or angle grinder with a metal-cutting disc. The PVC insert can be trimmed separately to match. Always measure each step carefully before cutting to ensure a precise, professional fit.
Which aluminium finish should I choose?
The choice of finish is primarily aesthetic and should complement the surrounding floor finishes, handrails and décor. Bright Polished and Mirrorflect Gold offer a high-shine, contemporary look. Satin Black and Dark Bronze suit modern or industrial interiors. Mill Finish provides a clean, understated appearance. Satin Gold adds a warm, premium tone. All finishes are available in the same profile dimensions.
What substrates can this stair nosing be fixed to?
This aluminium stair nosing is suitable for installation onto concrete, timber, stone and most other solid stair substrates. It should be fixed using appropriate mechanical fixings (such as countersunk screws) and, where required, a compatible adhesive. For external applications, ensure all fixings and adhesives are rated for outdoor use.
How do I maintain and clean this stair nosing?
This profile is low maintenance. Regular cleaning with a mild detergent and water is sufficient for most environments. Avoid abrasive cleaners on polished or decorative finishes. The PVC insert can be cleaned in the same way. In outdoor locations, periodic inspection of fixings and sealant is recommended to ensure continued performance.
Please note: Stock lengths are supplied as standard. Profiles can be cut to the required length on site. All dimensions stated are nominal. Tread: 56mm  |  Riser: 32mm  |  Gauge: 3.5mm.
