Balustrade Systems

Spider Stair Balustrade

A frameless-look stair balustrade where stainless steel point fixings hold the glass in place.

A spider stair balustrade is formed by fixing tempered or laminated glass to the floor or a side wall with stainless steel point fixings, known as spiders. Since no vertical post or channel is used, the glass surface reads as uninterrupted, giving the space a light, open feel. Metalux handles the process from the structural calculation of the fixing points to the glass installation, with its own team.

Where is it used?

The system suits interior staircases, balustrades enclosing a mezzanine, double-height living room voids, and projects or homes seeking a frameless balustrade in keeping with modern architecture.

Advantages

With no vertical profile, the glass surface reads as continuous and makes the space feel more open
Point fixings let the balustrade sit elegantly integrated with the architectural design
A laminated glass option limits the scattering of fragments if the pane breaks
Stainless fixings keep their appearance over time in interior use

Things to consider

The number and position of the spider fixing points are set by structural calculation, based on glass size and the supporting floor structure. Balustrade height and glass thickness should be designed to suit the specific setting. Periodic checks of fixing tightness are recommended.
