STAIR TREAD TYPES

MILD STEEL AND ALUMINIUM

We can supply  stair treads at any width and length to suit your application.  Stair treads can be supplied with either a banded end / welded fixing or bolted end to suit your requirements.  To complement our stair treads we can also provide them with no nosing, a floor plate nosing or a  yellow abrasive nosing to best suit your application.

*Photos above show stair treads manufactured from mild steel galvanised grating

Please note* AS1657 states "the nosing shall be such that the edge of the stair tread is clearly visible against the background"

RECOMMENDED MAXIMUM SPAN FOR MILD STEEL AND ALUMINIUM GRATING TYPES

MILD STEEL

ALUMINIUM

*Please note "the going shall not be less than 215mm" to comply with AS1657

STANDARD END PLATES: MILD STEEL AND ALUMINIUM

Standard end plates for stair treads are manufactured from 65x5mm flat bar for grating up to 40mm in depth.  Non standard end cleats can be made on request.

RECOMMENDED END PLATES FOR VARIOUS STAIR TREAD WIDTHS

 

For 125mm stair tread width
For 155, 165, 185mm stair tread widths

 For 205mm, 215mm, 245mm, 275mm, 285mm, 305mm, 325mm Stair Tread Widths

RECOMMENDED HOLE CENTRES FOR SLOTTED END PLATES

  • 205, 215mm = 100mm centres
  • 245,275,285,305,325mm = 125mm centres

 

TOE BOARDS ON STAIR TREADS

Toe Boards can be incorporated into any of the above stair tread types in both Mild steel and Aluminium.  A toe board is typically a flat bar welded to the back edge of a stair tread at a nominated height above the stair tread to close the openings  between risers. Toe boards are optional and need to be specified if required at the time of ordering/quoting.

FRP STAIR TREADS

RECOMMENDED MAXIMUM SPANS FOR FRP STAIR TREADS

*The recommended maximum spans are for static conditions. 
*Deflections for impact loads or dynamic load will be in excess of 5mm
*Long term loads will result in additional deflections due to creep in the material
*For applications at elevated temperatures, please consult Steel Grating Ltd
*Moulded stair tread spans are based on whole square dimensions as this is what is required for the installation of moulded FRP stair treads.

 

*FRP stair treads require a minimum of 40mm support surface at each end for the grating to sit on and require 4 off stainless steel "M" clips per stair tread for fixing to the supporting structure.
