Aluminium Stair Nosing 63.5x30mm Raked Back

If you are refurbishing a staircase and the floor covering is staying put, the raked back is the profile that solves the joint. The rear edge of this 63.5mm tread plate tapers from a 4mm gauge down to roughly 1mm, so it lands onto existing vinyl, LVT, laminate, engineered board or hard tile without leaving a ridge for a toe to catch. This page carries the three designer finishes — bronze, light bronze and black anodised — for stairs where a silver edge would look wrong.

Why it works

The taper is the point

A flat-backed nosing sitting on top of a finished floor creates a 4mm lip across the full width of every step. On a stair that is a trip hazard and a dirt trap, and it is the first thing to lift under a mop or a vacuum head. Ramping the back edge down to about 1mm removes it. The transition is shallow enough to walk over without registering it, and shallow enough that a broadloom carpet or a vinyl sheet can be dressed over the edge if you want the joint hidden completely.

Three finishes that are not silver

Bronze is the deeper, warmer tone and light bronze the paler, brassier one; they cost the same, so the choice is purely visual and worth ordering a sample of each. Both read as aged brass at a fraction of solid brass money. Black anodised is the one to pick when you want the metal to recede into a dark floor and the insert to carry the contrast. The extrusion, the channel and the thirty-two inserts are identical to the mill, satin and polished version of this nosing.

Pick the insert for the surface, not the swatch

The infill is what a foot actually contacts, and the manufacturer publishes slip potential figures for each type. Castellated PVC is the workhorse at SRV 76 wet / 85 dry. Olympic Grip, a coarse gritted band, is the highest at SRV 71 wet / 102 dry and is the one to choose where footwear arrives damp. Smooth textured PVC sits at SRV 56 wet / 65 dry and is a styling choice for dry interiors. The aluminium infills, which give a monolithic metal look, read SRV 54 wet / 82 dry. Those are figures for the insert material, not for a finished installation, but they are the right basis for a comparison between options.

Where it is used

Refurbishment work where the stair is part of the scheme: hotel and restaurant flights, reception and lobby stairs, boutique retail, apartment common parts specified to a finish schedule, and domestic staircases being relaid over an existing floor. It suits stone and timber stairs and stairs finished in ceramics, laminate, LVT, vinyl and lino.

Specifications

Choosing the right option

Finish. Bronze and light bronze cost the same and differ only in tone; black anodised is the darkest and the most forgiving next to a dark floor. All three are anodised coatings, so do not overtighten fixings and keep abrasive pads off them.

Length. Order the bar that covers your going in one piece. A 2.0 m bar cuts down to two 900 mm domestic treads with an offcut; a 1.0 m bar suits a standard domestic stair with a little to trim. If your treads are an awkward width, order from the cut-to-size version of this profile instead.

Drilling. Bars ship undrilled, so you can set out the fixings to miss joists, ducts and existing screw lines. The manufacturer will pre-drill for concealing plugs or for a retro-fit infill and charges 5% for it — tell us which you want and we will quote it with your order rather than loading it onto every price on this page.

Contrast. Bronze and black anodised are dark carriers, so if the stair is a means of escape or is used by people with impaired vision, put a genuinely light insert against them. What matters is the tonal gap, not the hue.

Installation, use and care

The substrate must be sound, clean, dry and flat. Cut to length with a fine-toothed blade in a mitre saw and deburr the cut end. Set out fixings at roughly 250-300 mm centres, starting about 50 mm in from each end, drill and plug the tread, then screw down evenly so the nose sits in continuous contact with the riser face. Do not overtighten a bronze or anodised bar; the finish will mark. Clean with a damp cloth and a neutral detergent. Avoid abrasive pads and solvent cleaners, which will dull an anodised surface.

One honest limit: this is a 4 mm gauge interior profile rated for low to medium traffic. Sustained heavy footfall or trolley impact will eventually wear through the anodising to the aluminium beneath. For external, wet or genuinely high-traffic locations, ask us about the glass-fibre reinforced insert build of the same profile.

Frequently asked questions

Will it sit flush on my existing floor?

Yes, that is what the raked back is for. The rear edge tapers to about 1 mm, so it lands on top of a finished floor covering without a pronounced lip. On a new lay where the covering will be brought up to the nosing, a square back profile is the better choice.

Where are the mill, satin and polished finishes?

On the companion listing for the same profile. We split the range across two pages because one page cannot offer six finishes, thirty-two inserts and both bar lengths at once without some combinations becoming unselectable at the checkout.

Can I have the bars pre-drilled?

Yes, but it is quoted rather than sold here. The manufacturer offers drilling for concealing plugs and drilling with a retro-fit infill, and charges 5%. Bars on this page ship undrilled; ask us and we will price the drilling alongside your order.

Can I use it outdoors or on a heavy-traffic stair?

No. This build is specified by its manufacturer for interior stairs carrying low to medium traffic. Heavy impact or high footfall can wear through the finish. There is a glass-fibre reinforced insert version of the same profile for external and high-traffic work.

Which infill should I pick for a wet entrance stair?

Olympic Grip. It is the coarsest of the four insert types and carries the manufacturer's highest published wet figure of the group, SRV 71. Castellated PVC at SRV 76 wet is very close and is the more common commercial choice.

Ordering and delivery

All 192 combinations on this page are made to order and dispatched from stock lengths. Standard UK mainland delivery is a flat rate. Order one bar to check the finish against your floor before committing to a whole flight; bronze and anodised finishes photograph differently from how they read on site.
