Austvision SpiderTread

Glass Stair Tread System


The Austvision SpiderTread System utilises Safelite Toughened Laminated Safety Glass (TLSG) combined with printed and non-slip surfaces to provide an attractive alternative to traditional stair treads.


The imposed floor actions are transferred from the glass through the Austvision spider fittings to the stair stringer. The laminated glass treads are fixed off the spider fitting using countersunk fixings which creates a flush surface.



The SpiderTread System is supplied with the Austvision 445 series heavy duty spider fitting using  M10 countersunk fixings.


Material and Finish

All fittings are cast 316 marine grade stainless steel in satin and polished finish.



The SpiderTread System can be used with Metro GlassTech  SafeLite Toughened Laminated Safety Glass (TLSG) with or without TempaGrip non-slip glass surfaces.



  • Suitable for up to 40mm TLSG
  • Fittings capable of supporting up to 8kN dead load per tread*
