Q Range Wide - (Alternative to Double Channel) Stair Nosing/ Stair Edging for No Floorcovering Including Ramped Back

Wide tread ramped back stair nosing profiles, providing an alternative to the traditional double channel stair nosings used on stairs with heavy foot traffic.

Features and benefits:

  • Suitable for installation in all categories of public and commercial buildings.
  • Ramped back edges - suitable for use when no floorcovering is present.
  • No dirt traps - easy to clean.
  • All over tread design provides a slip resistant surface from the nose to the back edge, giving the benefit of extra safety when ascending or descending stairs.
  • Satin etched aluminium riser surface is scratch resistant and inhibits the potential for 'glare'; one of the requirements of the BS 8300:2:2018 and Building Regulation guidelines applicable to stairways in areas of Public Access.

Potential for slip (all treads):

Independently tested by Grip Potential Ltd. All tread options have a minimum PTV of 36+ in a wet test and 60+ in a dry test; this is considered ‘Low Slip Potential’.
