Stair Nosings (Stairnosings) or Stair Edgings, are shaped and profiled strips of material (usually metal or uPVC) that are fitted on the edge of steps. They should span the full width of the step and should provide an anti slip function to step edges. They should also provide luminance contrast between step edge and surrounding step surfaces.

Treadsafe Distributors, with over 20 years experience in safety flooring, offer a complete sourcing, specification, cutting, drilling and delivery service for all types of aluminium and uPVC profiles. We can offer a wide range of profiles, finishes and colour combinations to suit your project.

Our stair nosing products are suited for all commercial, industrial and domestic projects throughout Ireland. We can help your building or project conform to the latest safety standards and building regulations.

There are four basic shapes (profiles) that fit the nose profile of the step – Square, Rake Back, Chevron and Bullnose.

  • Square stair nosing is fitted to steps that are at a 90º angle to the tread.
  • Bull-nosed stair nosings are fitted to steps that have a round edge, a wide majority of which are found when installing stair nosing to a wooden staircase.
  • Raked back stair nosings are fitted to steps that are at an 83º angle to the tread. Rake back staircases are common in more modern applications
  • Chevron stair nosings are often used to accommodate all step profiles.

The above four main profiles are the standard shapes that a stair nosing will follow. These four profiles are available in different materials, colors and sizes e.g. size of the tread and riser will vary depending upon the installation requirements.

We can also supply a ramped designs for safety (anti trip hazard). These ramp edged stair nosings are most suitable for laminate floors, vinyl and lightweight carpet coverings. Exterior stair nosings – without inserts – drilled or stickdown also are available

Gauge refers to the thickness of the stair nosing. The floor covering thickness will determine the gauge of the stair nosing.

Quality Brands

We stock quality stair nosing products from industry leaders such as Morleys, Quantum, Genesis and CAT – ensuring we have the right solutions for your requirements.

Building Regulations

We can supply Light Reflectance Values (LRVS) for stair nosing where required, to comply with building regulations. Individuals with impaired sight risk tripping or losing their balance if there is no visual reference or warning that steps provide a change in level. The risk is highest at the head of a flight of steps when a person is descending. The change in level can be clearly highlighted with a nosing that contrasts with the surrounding tread and riser materials. Our method of installation means changing top step insert colours is a formality. The colour contrast variation should be at least 30 points (for example black to white is 100 points) on all treads. We can advise that nosings are made apparent by means of a permanently contrasting material on both the tread and riser. Other considerations, such as step size and type, should be taken when choosing a nosing.

Installation of Stair Nosings

  • Ensure that the stair surface is level and flat.
  • Select the most suitable cartridge adhesive for interior/exterior usage.
  • Ensure stairs are clean and free of debris, dust, grease and oil.
  • Check the stair is dry and free from dampness.
  • Select the nosing carrier and check for the correct fit on the required stair.
  • Do not apply the insert material at this stage.
  • Carefully mark through the drill holes, ensuring that the nosing is tight against the riser, carpet or vinyl.
  • Remove nosing from the stair, and drill and plug the tread ready for installation.
  • Apply the adhesive to the underside of the nosing and replace on the step.
  • Remove the nosing and allow the adhesive to cure for the recommended time.
  • Replace and refit the nosing carrier to the stair tread, and screw down firmly.
  • Ensure that the screws are flush to avoid ‘show through’ on the insert material.
  • Peel back the double sided tape, ensuring no dust or fibre is allowed onto the surface.
  • Place insert material (smooth side down) into the channel from both ends, and smooth into the middle of the profile.

Maintenance of Stair Nosing and Trims

To maintain the appearance and performance of Treads stair nosings to the highest standards, we recommend the following maintenance regime:

  • Avoid acids, alkalis, strong detergents and any type of polish that may reduce the anti-slip properties of the nosing.
  • Weekly cleaning is advised, but a more frequent regime needs to be considered in heavy traffic areas.
  • Remove immediately any build up of dirt and grease that may cause a hazard.
    Clean inserts with a mild detergent diluted in water.
  • Carefully wipe over the nosing with a damp cloth and then wipe dry with a clean dry cloth.
  • For long term care the aluminium can be lightly buffed using a suitable burnished steel wool.

Templates should be supplied on card or similar weight material.
Take the template from the extreme front edge of the step, including a minimum of 250mm of the straight section.

On the top of the template please include the following information:

  • Customer name
  • Profile type and number
  • Insert colour
  • Drilled or undrilled

Flooring Key Terms

The vertical part of the step/nosing

Tread Material

This is the anti slip material that is secured in the channel of the stair nosing. It is also known as the Infill material.


This term describes the thickness of a floor covering. Quantum use two gauges: slim gauge (e.g. vinyl flooring) and heavy gauge (e.g. carpet).
