Single Channel Rake Back Aluminium Stair Nosing — 70mm Tread with Exterior Grip PVC Insert

A precision-engineered aluminium stair nosing profile designed to protect and define the leading edge of steps on internal and external staircases. Featuring a single-channel rake back body with a 70mm tread, 32mm riser, and a 3.5mm gauge aluminium alloy profile, this nosing accepts a high-performance slip-resistant PVC exterior grip insert to deliver reliable underfoot traction in commercial, public, and residential settings. Supplied in three stock lengths and available in six aluminium finishes paired with three exterior grip insert colours, it is a versatile, long-lasting solution for new-build and refurbishment stair projects.

Technical Specifications

Product Features

• 70mm tread with a single PVC insert channel providing a clearly defined, slip-resistant step edge.
• Rake back (ramp back) profile geometry designed to sit flush against the stair riser for a clean, professional finish.
• 3.5mm gauge aluminium alloy construction — robust enough for high-traffic commercial environments while remaining lightweight for handling and cutting on site.
• Exterior Grip PVC inserts engineered for use in exposed and outdoor locations where moisture and contaminants are present.
• Six aluminium finishes — Bright Polished, Dark Bronze, Mill Finish, Mirrorflect Gold, Satin Black, and Satin Gold — to complement a wide range of interior and exterior design schemes.
• Three insert colour options — Brimstone, Coal, and Everest — each in Exterior Grip formulation, supporting visual contrast at the step edge.
• Stock lengths of 2.44m, 2.75m, and 3.22m minimise joints across wider stair flights and reduce material waste.
• Mechanically fixed through the aluminium channel to the stair substrate using screws, ensuring a secure and stable installation.
• Compatible with vinyl, LVT, timber, and other hard floor finishes at the stair tread level.
• Low-maintenance surface that withstands sustained pedestrian traffic without significant degradation.

Key Benefits

• Reduces slip and trip risk at the stair edge in both dry and wet underfoot conditions.
• Exterior Grip insert formulation extends suitability to outdoor and exposed stairways — a single profile for internal and external applications.
• Visual contrast between aluminium finish and insert colour aids step-edge visibility, supporting safer stair navigation.
• Long stock lengths deliver a neater, joint-free appearance across wide stair flights.
• Hard-wearing aluminium edge protection prolongs the life of the underlying stair tread surface.
• Site-cuttable profile allows efficient, accurate installation on refurbishment and new-build projects of any scale.

Applications

This rake back single channel stair nosing is suited to a broad range of stair environments where a durable, slip-resistant aluminium edge profile is required:

• Commercial office buildings, retail premises, and hospitality venues with regular pedestrian traffic.
• Educational institutions, healthcare facilities, and public sector buildings.
• Apartment blocks, communal entrance stairs, and residential developments.
• External access steps, entrance stairs, and exposed stairways — using Exterior Grip insert options.
• Refurbishment of worn or unprotected stair edges to restore safety and extend step life.
• New-build stair fit-outs on concrete, timber, or tiled substrates with vinyl, LVT, or hard floor finishes.
