Suitable for use on external concrete, stone or timber steps, this nosing supports compliance with DDA (Disability Discrimination Act) and Equality Act guidance by improving step visibility and underfoot grip. Available in a choice of tread colours and lengths, it is ideal for public buildings, commercial entrances, fire escapes, ramps and external staircases.

Product Features

  • Durable aluminium stair nosing with 57 mm tread and 55 mm riser dimensions for robust edge protection.
  • External-grade anti-slip insert for reliable traction in wet, cold or contaminated outdoor conditions.
