Safegrid Treads

Compliant and sustainable steel stair treads

Lionweld Kennedy have obtained the world’s first Environmental Product Declaration for steel grating!


As part of our efforts to lead a better change within the industry, obtaining the EPD for our low-carbon, infinitely recyclable Safegrid products cements our commitment to our ESG plan and minimising our impact on the world.


Safegrid Treads are the Lionweld Kennedy range of stair treads.

Manufactured to comply with 35mm or 20mm ball proof requirements, in accordance with BS4592-0:2006+A1:2012, with a nosing bar welded to the front edge and welded integral end plates drilled to allow for bolting to stair stringers.

The nosing bar is attached along the full width of the leading edge and this is selected to suit the requirements of the project, considering slip resistance, visibility and loading. 


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

Nosing is a vital component of a stair tread as it provides multiple characteristics:

  • 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-Visibility. 

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

End plates and 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 for flexibility during installation.


Your choice of stair tread should be based on your ball proof requirement dependent on where the stairs will be located and the volume of traffic passing underneath.


The tread width is determined by the flooring pitch and manufactured to a range of standard sizes.

Bespoke widths can be manufactured to suit your specific project, however upsizing the next standard size is usually a cost-effective alternative.


The tread length 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.
