Sustainable and safe stair tread access solutions.


Safetreads is the Lionweld Kennedy range of stair treads.

These are constructed using an open steel grating from the flooring range with a nosing bar or sight bar welded to the front edge and welded integral end plates which are drilled to allow for bolting to stair stringers.

The nosing bar or sight bar is supplied along the full width of the leading edge and this is selected depending upon the requirements of the project in terms of slip resistance or high visibility. 

The treads themselves are supplied in standard widths which are determined by the flooring pitch.

Lionweld Kennedy stair treads have been designed to help our customer comply with BS4592-0:2006+A1:2012, utilising our Safegrid 35mm BP grating and 20mm BP grating.


A range of nosing options and sizes to suit your requirements.

Check out our downloadable product guides for the various widths and lengths available as standard.

Tread nosing is a vital component of a stair tread because it provides multiple characteristics to the tread.  These include:

  • Loading (loads are usually applied to the front edge/nosing of the tread)
  • Anti-slip surface to the front edge
  • Sight bar to help clearly locate each stair tread

The standard nosing options include Liongrip, Durbar or Hi-Vis. 

The British Standard advises a minimum going of 250mm plus a 16mm overlap, which means the minimum tread width should be 266mm.

For the end plates, the drilled hole positions have been standardised across the whole range of treads, however alternative drillings are available on request.

The end plate drilling consists of one fixed and one slotted hole to allow flexibility during installation.


In a similar way to selecting your Lionweld Kennedy Safegrid flooring, the choice of stair tread should be based on your ball proofing requirements dependent on where the stairs will be used and the volume of traffic.


The stair width is determined by the flooring pitch and are manufactured to the nearest bearing bar.

Alternatives widths can be manufactured to suit however upsizing the next standard size is usually acceptable and will cause a slight over-hang at the back of the stringer.


The stair width is determined by the distance between the stringers and based on load distribution requirements.

Lionweld Kennedy offer a standard range of lengths to suit the majority of applications.
