A 70 x 32mm rake back aluminium stair nosing with a ramped rear edge and a textured High Grip insert. It combines an angled front leg for sloping risers with a ramp at the back for hard floors, so it suits concrete and steel stairs finished in LVT, wood or vinyl. It is the profile to choose when neither a square nosing nor a standard upstand fits.
Choose Obsidian or Solar insert in any of nine aluminium finishes, in 2.44m, 2.75m or 3.22m stock lengths for cutting on site.
Why this nosing works
Two problems, one profile
The 32mm front leg leans back to follow a raked riser, so it seats along its full depth. At the back of the 70mm top leg, the ramp tapers down to floor level, so LVT, wood and other hard floors meet it with no raised lip.
Tested grip, wet and dry
A smooth PVC insert is fine on a dry, quiet stair. Once a step gets wet, grip comes from texture. This insert has a textured PVC face, and its pendulum results are 95 dry and 60 wet, measured by an independent laboratory. Under UK Slip Resistance Group guidance, 36 or more means low slip potential. One full-width strip sits on the step edge, exactly where feet land as people come down the stair.
An edge people can see
The insert colour does the safety work. Solar, a golden yellow at LRV 55.10, stands out on grey, blue and dark floors. Obsidian, a near-black at LRV 1.80, stands out on beige, white and light grey. Your floorcovering's LRV is on its data sheet.
Where it fits in the range
If your risers are vertical, the 70 x 32mm square front ramp back is the better fit. If you are laying carpet, choose the 56 x 32mm rake back with a standard gauge.
Nine finishes
Mill Finish is plain aluminium for service and back-of-house stairs. Bright Polished and Satin Silver give a bright or soft silver line. Satin Gold, Satin Bronze, Dark Bronze and Satin Black suit timber-effect, stone-effect and dark floors. Mirrorflect Silver and Mirrorflect Gold are mirror-bright for reception and front-of-house stairs.

Choosing the right option
Insert colour. Pick for contrast. Solar on mid-grey, blue, green and dark floors; Obsidian on pale floors such as light grey, beige or white. Both colours are the same price.
Finish. Mill Finish is the lowest price, then Bright Polished, then Satin Gold. Dark Bronze, Satin Black, Satin Silver and Satin Bronze share the middle price. Mirrorflect Silver comes next. Mirrorflect Gold costs the most. Satin finishes hide scuffs best on busy stairs.
Length. Measure every step, then choose the stock length that cuts into those widths with the least waste. Order a spare where widths vary.
Installation, use & care
Cut each length to the step width with a fine-toothed blade for aluminium and de-burr the ends. The step must be clean, dry and sound. Screw-fix through the channel with fixings to suit the substrate, or bed the profile on a stair nosing adhesive. Clean and dry the channel, peel the backing from the self-adhesive insert and press it firmly into place over the fixings. Lay the floorcovering up to the ramped back so it finishes flush. Sweep and damp-mop the insert regularly, because trodden-in dirt fills the texture and reduces grip. Avoid abrasive pads on polished and coloured finishes.
Frequently asked questions
What are the slip test results for this insert?
The pendulum test results for this insert are 95 dry and 60 wet, measured at an independent friction-testing laboratory. Under UK Slip Resistance Group guidance, a pendulum value of 36 or more indicates low slip potential, so the insert stays well above that line when wet. The figures apply to a clean insert, so keep the textured face free of dirt and polish build-up.
What is the difference between rake back and ramp back?
Rake back describes the front leg, which is angled to follow a riser that slopes back under the nose. Ramp back describes the rear of the profile, which tapers down to floor level for hard floors. This nosing has both.
Can I use this nosing outside?
No. The High Grip insert is rated for internal use, with a service temperature range of -10°C to 80°C. For external steps, choose a profile with an exterior-grade insert, which is listed separately.
Which floors is it designed for?
Vinyl, LVT, wood and other hard flooring. The ramped back gives a smooth transition without a lip. For carpet, use a standard rake back profile.
Obsidian or Solar: which insert colour should I choose?
Choose by contrast with the floor, not by matching it. Obsidian has an LRV of 1.80 and Solar 55.10. Aim for a difference of more than 30 LRV points between the insert and the surrounding floor: Solar for mid and dark floors, Obsidian for pale ones. Your floorcovering manufacturer publishes its LRV on the product data sheet.
