Heavy Duty Aluminium Stair Nosing with Anti-Slip PVC Insert — Commercial & Industrial Grade

When stair safety cannot be compromised, this heavy duty aluminium stair nosing delivers the specification demanded by architects, contractors and facilities managers. Constructed from a thick 5mm gauge aluminium extrusion, it is engineered specifically for the demands of commercial, industrial and public building staircases — locations where standard domestic nosings simply fail under sustained footfall.

The profile is supplied in two designs to suit different stair geometries and covering types:

• NHD05 Straight — 32mm riser × 60mm tread, straight back, ideal for carpet-covered stairs in commercial interiors
• NHD06 Rakeback — angled rear face, designed where the riser meets the tread at a non-standard angle or where the profile must be recessed into the stair edge

Anti-Slip Performance Specification

The coloured PVC anti-slip insert is manufactured using Tredsafe® compound — a proprietary blend of PVC, silica quartz and polymeric plasticiser. This formulation creates a three-dimensional pyramid surface pattern that provides exceptional slip resistance under both wet and dry conditions, critical for staircases in environments where spillages, outdoor ingress or wet shoes present a constant hazard.

Insert Colour Selection Guide

Choosing the correct insert colour is not purely aesthetic — under DDA and BS8300 guidelines, stair nosings must provide sufficient Light Reflectance Value (LRV) contrast against the surrounding floor surface (minimum 30 LRV point difference recommended):

• Yellow — highest visibility, ideal for DDA compliance in public buildings, educational facilities and industrial environments. Mandated in many local authority and NHS specifications.
• Black — strong contrast against light-coloured carpet and tile. Popular in commercial offices, retail and hospitality settings.
• White — contrasts clearly against dark carpet tones. Clean appearance suited to contemporary interiors.
• Midnight Grey — versatile mid-tone option that blends with grey carpet whilst providing adequate contrast against lighter surrounding surfaces.
• Channel Only — bare aluminium profile supplied without insert. Order separately or specify when replacing inserts on existing nosing installations.

Applications

• Schools, colleges and universities — high footfall corridors and stair blocks
• Offices and commercial buildings — carpet-covered fire escape and feature staircases
• Hospitals and healthcare facilities — DDA-compliant nosings for patient and visitor areas
• Hotels, shopping centres and retail environments — appearance-conscious nosings with safety performance
• Industrial and warehouse staircases — heavy load bearing, wet-area and external-grade applications
• Residential apartment blocks — communal staircases requiring compliant anti-slip edge protection

Cut-to-Length & Bespoke Drilling Service

Standard lengths cover most installations. For staircases where a precise cut length is required, or where countersunk screw holes must be pre-drilled at specific centres, a bespoke cut-to-length and drilling service is available. Please contact us before ordering to discuss your requirements — bespoke orders are non-returnable once cut or drilled.

Installation Notes

The NHD profile is designed for mechanical fixing using countersunk screws into the stair substrate. The 5mm aluminium wall thickness allows firm fixing without distortion. For carpet-covered stairs, the profile is typically positioned at the stair edge with carpet fitted up to and tucked beneath the tread flange. On hard floor surfaces, fixing adhesive may be used in addition to mechanical fixings for additional security on heavily trafficked routes.

Extender connector profiles are available for NHD05 and NHD06 where sections must be joined across wide staircases — sold separately.
