Semi framed steel and glass balustrade

The G2 semi-frameless balustrade design is one of the most elegant balustrade formats in the Arden catalogue.
Design 

Glass panels are surrounded by a full perimeter stainless or mild steel frame, with glazing channel top and bottom. Clear space between glass and frame is maintained laterally on each side. The frame and handrail is supported by stanchions (typically SHS or blade profile stainless / mild steel) interposed between each panel. The vertical frame members may be hard up again each side of the stanchion, or set-back by small off-stands (typically steel rod). The entire balustrade section may be capped with a handrail of any material and profile, and / or combined with an offset handrail. Finally, the semi-framed panels may be fixed to the treads / structural floor, fixed to a stringer such as a PFC, or face fixed to the stringer or treads.

All implementations of the G2 tend to share a sense of luxury and even opulence. This is demonstrated by the some of the featured images, where crisp white stone, American Oak and built in lights accentuate the effect. Even when the materials chosen are restricted to only stainless steel and glass, the interactions of geometry between the various components create a fine, intricate impression.

Technical

In this balustrade style, the glass component is infill glass with continuous support on the top and bottom edges. The continuous support of the glass (as opposed to patch fittings, being point loads) allows the specification of the laminated glass as infill glass, although toughened and toughened laminate could also be used. Arden suggests standard methods for approaching both the glazing channel frames and the blade stanchion supports. Some variation in the specific glazing profile and stanchion dimensions may be made for aesthetic or engineering considerations, depending on the specific properties of each project. Handrail fixing is always offset from the stanchion, either vertically or horizontally. Handrail profile style may be selected from Arden technical document A.4 ‘Handrail profiles’ or a custom profile may be specified.
