Steel SHS stanchions supporting glass panel infill on through-glass patch fittings
Stainless steel SHS stanchions support glass infill panels on through-glass patch-fittings in this design.
Stainless steel SHS stanchions support glass infill panels on through-glass patch-fittings in this design. Off-stand cylindrical bodies may be extended so as to allow the glass to overhang the edge of the void or staircase. The neutral tones of stainless steel and glass combine easily with a variety of other materials, such as timber or stone. Handrail (50.8mm CHS typical) is generally mounted vertically on a mounting pin above the stanchion, so that the handrail and stanchion centrelines coincide. The Arden C8 balustrade design offers the flexibility to complement many types of staircase or balustrade configuration, resulting in a clean, crisp and modern finish.
Glass and stainless steel provide strength and durability, ensuring that there are few limitations for architects and designers wishing to realise dramatic and dynamic infill designs. The high transparency and the neutral textures of the C8 design can also allow the balustrade to retreat visually, if necessary.
The C8 balustrade style is essentially a stanchion based balustrade system with infill glass supported off patch fittings mounted on the stanchions. The primary balustrade loads are carried by the handrail directly to the stanchions, and not via the glass, which reduces the design criteria of the glass to effectively that of “infill glass” as opposed to structural glass.
In terms of design then, the size and spacing of the stanchions are determined to suit the applicable balustrade load as defined by AS1170.1-2002 (Structural design actions), which defines the applicable loads for particular applications. The infill glass loads are also defined in the Australian Standard for the particular application and the sizing of the infill glass is then provided by AS1288-2006 (Glass in buildings, selection and installation).
It should be noted then that the final design in terms of stanchion spacing may be determined by issues in respect to the handrail loads as well as the span of the infill glass.
The C8 balustrade style can have a number of other variations that can be dependent upon the application environment, where the base materials may determine the style of stanchion fixing (e.g. void edge face fix as opposed to top fix) and may then also determine line of the stanchions relative to the void edge. Dependant upon preferences then, considerations such as the length of patch-fitting off-stand may become a factor.
