The edge that takes the wear.

Stair nosings, edge trims, thresholds and barrier matting. The details that decide whether a floor still looks finished in five years, and whether a stair is safe to use in the meantime.

Where it goes

Where the accessories matter.

The places a floor is asked to stop, turn or change level.

Stairs & escapes

A nosing on every tread, in a colour that reads against the floor.

Thresholds

Where two finishes meet, a trim holds both edges down.

Entrances

Barrier matting at the door, so grit stops before it reaches the floor.

Level changes

Ramped edge trims, so a change in height is not a trip.

The discipline

A nosing is a safety detail before it is a trim.

Guidance for accessible buildings comes down to one thing on a stair: the edge of every step has to be visible. That means a nosing that contrasts with the tread, on the tread and the riser both, and the same detail on every flight.

Nosings and trims are fitted as the flooring goes down rather than added afterwards, so the covering runs into the section instead of stopping short of it.

  • Trims fitted with the floor, not after it

Specifying a stair?

Tell us the flights, and what the floor either side is.

Tread counts, the covering on the stair, and whether the building stays open while it is fitted.
