Winged steel blade stanchions supporting glass panels with through-glass patch fittings

The W4 stanchions are an implementation of a toughened glass balustrade solution incorporating the PF10/PF12 Arden system patch fittings on horizontal outriggers.


 The W4 stanchions are an implementation of a toughened glass balustrade solution incorporating the PF10/PF12 Arden system patch fittings on horizontal outriggers. Either though-glass integrated patch-fitting / handrail mount assemblies or a direct stanchion handrail mounting method may be specified. With a variety of possible blade profile dimensions, and a range of flexible stanchion fixing methods, the W4 represents a complete commercial balustrade solution for high design loads in virtually any application. The blades and horizontal patch-fitting off-stands may be specified to be either stainless steel or powder-coated mild steel.

On staircase balustrade, W4 stanchions may be designed to be either vertical or perpendicular to the nosing line. In the case of vertical blades on a staircase, the relative height of the four patch fitting wings is offset, so that the patch fittings rise with the nosing line. In either case, the interactions of angle and line present a strikingly architectural impression.

Other alternatives for the architect or designer utilising the W4 system include varying the relative height of the top / base of handrail, stanchion, and glass lines. Face-mounted blades are considered by many to have greater architectural appeal, but the floor mounted version is also extremely effective. The arrangement of the handrail and glass on opposing sides of the stanchion is another alternative configuration of the W4.


 Please refer to the PF10/PF12 Arden brochure for details of the patch fittings used in the W4. The specification of either PF10 (M10 thru / 38d body) or PF12 (M12 thru / 50d body) will largely depend on the required design loads. Likewise, the selection of blade profile (60x12 / 65x16 / 75x20 are typical) will depend on engineering requirements, as well as visual considerations.

After detailing, W4 stanchions are welded in-factory before on-site installation. Where applicable, chemset fixings are generally preferred. Where this is not possible, a range of standard structural fixing types are possible

Minimal 8mm toughened glass infill panels with polished edges and tipped or rounded corners are used. Typically 38.1 diameter stainless steel handrails are used. However, a wide range of handrails, including timber, can also be used. The stanchion carries the potential loads and therefore the glass is rated as infill only.
