Polished Gold Precision — Where Safety Meets Architectural Elegance
The IDP-0147G Cover Nosing is a premium 46mm aluminium stair edge profile engineered for high-traffic environments where both safety and aesthetics are non-negotiable. Crafted from extruded heavy-duty aluminium with an elegant polished gold finish, it wraps cleanly over exposed step edges and raised floor thresholds, concealing raw terminations of tile, laminate, or vinyl flooring while delivering a flush, professional result. The integrated black rubber anti-slip insert adds critical foot traction, making it a functional and decorative solution for residential and commercial staircases alike.

- Premium Extruded Aluminium Body (46mm wide, 2.5m length): Each IDP-0147G profile is cold-extruded from high-grade aluminium alloy, producing a rigid, dimensionally stable section measuring 4.9 × 25 × 46 mm over a 2500 mm run. The extrusion process ensures consistent wall thickness and precise geometry, making it resistant to bending, warping, or permanent deformation under sustained foot traffic and point-load impact — a critical requirement for busy staircase landings.
- Textured Black Rubber Anti-Slip Insert for Certified Traction: The recessed central channel houses a co-extruded, textured black rubber strip that runs the full 2.5 m length of the profile. The rubber compound is engineered for durability under repetitive compression, maintaining its grip performance over thousands of footfall cycles. The high-contrast black rubber against the polished gold frame also serves as a visual step-edge indicator, enhancing safety compliance in both residential and commercial settings.
- Overlapping Bullnose Geometry Conceals and Protects: The profile's curved, overlapping nose is specifically designed to drape over and fully enclose exposed step-edge corners — whether the substrate is ceramic tile, porcelain, laminate plank, or luxury vinyl tile. This eliminates sharp, chipped, or rough floor terminations at the most vulnerable point of a staircase, reducing the risk of trips, abrasion injuries, and progressive edge deterioration. Net weight of just 0.193 kg per 2.5 m length ensures it adds negligible load to the structure.
- Pre-Punched Fixing Slots for Rapid, Accurate Installation: Evenly spaced countersunk mounting slots are pre-drilled along the aluminium base flange, allowing direct fixing with standard floor screws. The slot geometry permits minor lateral adjustment during fitting, compensating for small substrate irregularities and ensuring the profile sits perfectly flush. The profile is also compatible with construction adhesive for adhesive-only or combined screw-and-adhesive applications on sensitive substrates where drilling is undesirable.
- Polished Gold Finish — 30517 Colour Reference: The polished gold anodised or lacquered surface treatment (colour code 30517) delivers a warm, lustrous metallic appearance that coordinates with brass hardware, golden door frames, and classic interior schemes. The finish is applied over the full visible face of the aluminium extrusion, ensuring the frame surrounding the black rubber insert presents a consistently high-end decorative border. Unlike painted finishes, the polished surface is scratch-resistant and retains its appearance in high-contact areas.
- Lightweight yet Structurally Rigid at 0.193 kg per 2.5 m: The aluminium material delivers an exceptional strength-to-weight ratio, making the IDP-0147G easy to handle, cut to length with a mitre saw or angle grinder, and position accurately during installation. The low mass (0.193 kg) means two-person handling is not required even on full-length 2.5 m runs, speeding up installation workflows on multi-step projects.
The IDP-0147G Cover Nosing is supplied as one complete 2500 mm profile per piece, ready for immediate installation on residential or commercial step edges.
General Purchase & Comparison Queries
What makes the IDP-0147G different from a standard stair nosing profile?
Unlike flat transition strips or basic edge trims, the IDP-0147G is a cover nosing — its overlapping bullnose geometry physically wraps over and around the step edge, fully enclosing raw flooring terminations from above. This provides superior edge protection compared to profiles that simply butt up against the step face. The combination of a heavy-duty extruded aluminium body, an integrated black rubber anti-slip strip, and a decorative polished gold finish (30517) means one product addresses structural protection, slip resistance, and interior aesthetics simultaneously.
Is this profile suitable for both residential and commercial projects?
Yes. The extruded aluminium construction and full-length rubber anti-slip insert are engineered to perform in high-footfall environments including commercial offices, hospitality venues, retail spaces, and public stairwells, as well as residential staircases and home interiors. The polished gold finish suits upscale interior schemes where a premium decorative border is desirable alongside the functional black rubber tread surface.
What length does the IDP-0147G come in, and can it be cut to size?
Each IDP-0147G profile has a standard length of 2500 mm (2.5 metres), which covers most standard staircase widths in a single unjointed run. The aluminium extrusion can be cut to any shorter length on-site using a mitre saw, angle grinder, or fine-tooth metal blade. Its low net weight of 0.193 kg per 2.5 m length makes handling and cutting straightforward for a single installer.
Product-Specific and Usage Queries
What flooring types is the IDP-0147G compatible with?
The overlapping cover nosing design is compatible with ceramic tile, porcelain tile, laminate plank, luxury vinyl tile (LVT), and vinyl sheet flooring. The profile's curved nose drapes over the step edge to conceal the raw cut termination of whichever floor covering is used on the stair tread, producing a clean, professional finish without requiring specialist edge-finishing tools or additional beading.
How is the IDP-0147G fixed to the step — screws, adhesive, or both?
The profile features pre-punched countersunk fixing slots evenly spaced along the aluminium base flange for direct mechanical fixing with standard floor screws, which is the recommended primary method for maximum long-term security. For sensitive substrates where drilling is not advisable, the profile is also compatible with a high-strength construction adhesive applied to the base flange. A combined screw-and-adhesive approach can be used for critical installations subject to heavy impact or vibration.
What are the exact dimensions of the IDP-0147G profile?
The IDP-0147G has a cross-sectional dimension of 4.9 mm (height) × 25 mm (base width) × 46 mm (overall nose width), with a total length of 2500 mm. The 46 mm nose width provides ample coverage over standard step-edge terminations, while the low 4.9 mm rise ensures a smooth, low-profile transition that does not create a secondary trip hazard at the stair edge.
Problem/Solution-Oriented Queries
The edge of my tiled staircase is chipping and looks unfinished — will this profile fix it?
Yes. The overlapping bullnose geometry of the IDP-0147G is specifically designed to cover and protect exposed, chipped, or rough tile and laminate terminations at step edges. Once fixed in place, the aluminium nose fully encloses the vulnerable corner, preventing further chipping or delamination from foot traffic impact, and delivering a clean, flush, professional finish that conceals the existing damage without requiring retiling.
My current stair nosing has no grip and is becoming a slip hazard — how does the IDP-0147G address this?
The IDP-0147G integrates a co-extruded textured black rubber anti-slip strip that runs the full 2500 mm length of the profile. The rubber compound is engineered to maintain grip performance across thousands of footfall cycles without cracking, shrinking, or detaching. The high-contrast black rubber against the polished gold aluminium frame also functions as a visual step-edge indicator, helping users identify the step boundary clearly — a dual safety benefit that plain metal nosings cannot provide.
Will the polished gold finish tarnish or corrode over time in a high-traffic area?
The polished gold surface treatment is applied over an aluminium substrate that is inherently corrosion-resistant due to its natural oxide layer. Unlike brass or copper alloys, aluminium does not tarnish in normal interior conditions. The polished finish is scratch-resistant compared to painted surfaces, and the underlying aluminium extrusion will not rust or corrode even in environments with moderate humidity, making the IDP-0147G a durable long-term investment for both residential and commercial staircases.
