Description
A 5mm gauge aluminium nosing with a carborundum grit insert: the general-purpose heavy-duty step edge for stairs that are walked on hard. The 77mm tread plate gives a broad landing area and the 40mm nose covers the vulnerable front arris where concrete spalls and floor coverings wear through first.
The 5mm gauge is the point
Thin nosings dish between fixings and drum underfoot. At 5mm this extrusion stays flat across a 300mm fixing centre and takes trolley wheels and impact without deforming, which is why it is the specification for schools, hospitals, transport buildings and industrial stairs rather than a 2.5mm domestic profile.
Why carborundum rather than PVC
Aluminium oxide grit in a resin matrix is the hardest of the common anti-slip infills. It does not burnish smooth under footfall the way a ribbed PVC insert does, and it cannot peel like a bonded grit tape. On a stair that justifies a 5mm carrier, a soft insert is the part that will fail first.

Choosing the right option
Finish. Mill is plain untreated aluminium for industrial and back-of-house stairs. Satin is anodised, holds its appearance better in a public area and resists finger marking.
Drilling. Undrilled lets you set the fixings out on site. Pre-drilled arrives countersunk on centres and saves real time on a long flight.
Length. Order the bar that covers your going in one piece, or use the cut-to-size version for anything between 250mm and 2750mm.
Installation, use and care
The substrate must be sound, clean and dry; make good a worn arris before fixing or the nose will bridge a hollow. Fix at roughly 300mm centres, starting about 50mm from each end. On external stairs bed the nose in a structural adhesive as well as screwing. Clean with a stiff brush and water; avoid acid and solvent cleaners on the resin.
