The AHD22 72 x 55mm Heavy-Duty Tredsafe Stair Nosing is a premium safety profile engineered for DDA-compliant stairways in commercial, industrial, and public access environments. With a 72mm tread and 55mm riser, it offers wide, highly visible step-edge protection—ideal for ensuring both accessibility and slip resistance in high-traffic areas.

As part of the trusted Tredsafe Aluminator® range, this profile incorporates a glow-in-the-dark insert that stores energy from daylight or artificial lighting. In low-light or emergency power loss conditions, the Aluminator® strip activates automatically—clearly defining the step edge and riser to support safe evacuation without the need for electricity, wiring, or maintenance.

The anti-slip Tredsafe insert provides reliable grip underfoot, helping to prevent slips and falls. Supplied pre-drilled through the insert with matching pips to conceal fixings. Optional undrilled versions or drilled channel-only profiles with separate inserts can be provided upon request. Fixings are not included and should be selected based on subfloor compatibility.
