The same raked back aluminium stair nosing as our stock-bar listing — 62mm tread, a 55mm front face raked back at 83°, 5.0mm gauge alloy 6063 T6 — but cut to whatever length your flight actually needs. Enter the measurement in millimetres, anywhere from 700mm to 2500mm, and every piece is cut to it with a ±5mm tolerance. Priced per metre, so you pay for what you order and nothing more.
Cutting to size is worth it on any flight where the goings are not all the same width — which, on a refurbishment, is most of them. Ordering to the millimetre is the difference between a clean line into each stringer and a row of visible cut ends.
If your going is close to a standard 1m or 2m bar, the stock-length version of this raked back nosing is usually the simpler order.
Why fitters choose this profile
The rake is what makes it disappear. The front face leans in under the step at 83° rather than hanging vertically, so the bottom edge sits behind the top edge. The nose stays out of the walking line, and the step edge reads as an angled shadow rather than a square block.
5mm gauge, so it stays flat. On a stair edge that thickness is the difference between a nosing that holds its line under load and one that dishes between fixings after a couple of years.
The insert carries the slip resistance. The tread plate is recessed for a full-width insert that sits proud of the metal — that is what your foot lands on. Manufacturer's published figures: castellated PVC SRV 76 wet / 85 dry; Olympic Grip 71 wet / 102 dry; smooth textured PVC 56 wet / 65 dry; aluminium insert 54 wet / 82 dry. Insert test figures, not a test of your finished stair — but real numbers you can put in front of a specifier.
The back edge interlocks with a nap detail for broadloom carpet, a tread extender and a ramp extension, so a whole flight can be detailed from one family of profiles.

Choosing the right option
Finish is the aluminium carrier — the metal around the insert and down the raked face. Colour is the insert sitting in the channel, which is why some combinations read as two metal names. Mill aluminium is the untreated extrusion and the cheapest of the six; satin and polished are anodised and hold their appearance better in a shared stairwell; black anodised, bronze and light bronze exist for appearance rather than performance.
Castellated PVC is the default insert and carries the highest wet figure of the four families — keep smooth textured away from entrance flights. If the stair is external, or takes heavy traffic and impact, this is the wrong profile: there is a build in mill aluminium with a glass-fibre reinforced (GRP) insert for those conditions, and we will quote it.
Installation, use and care
Measure each going before ordering and allow for the ±5mm cutting tolerance — if you want a tight fit into a stringer, order 3–5mm under and take up the difference with the insert. Drill and screw-fix the tread plate to the substrate with size 8 screws at regular centres; on timber steps the profile can be rebated so the plate finishes flush. Fit the nosing before the floorcovering is dressed up to the interlocking back edge, then trim the covering to abut the profile. Clean with a neutral floor cleaner and a damp mop; keep abrasive pads and solvent cleaners off the anodised and bronze finishes, which they cut through to bare aluminium.
Ordering and delivery
Select your finish and insert colour, enter the length in millimetres and set how many lengths you need — the price updates as you type. Cut pieces are made to your measurement and are non-returnable except where there is a fault; this does not affect your statutory rights. UK mainland delivery is a single flat rate at checkout. Matching ramp extensions, tread extenders and a nap detail for broadloom carpet are available — contact us and we will quote them alongside your nosings.
