The ArdenC4 balustrade system offersthe flexibility and simplicityto complement almost anystaircase1A and balustradeconfiguration, resulting in aclean, crisp and modern finish.Because of the inherentflexibility and strength ofthe materials, there are fewlimitations for architectsand designers wishing torealise dramatic and dynamicinfill designs. Alternatively,in situations where thebalustrade should retreatvisually, so as not to distractfrom other design elements,the neutral textures of the C4design can also satisfy thisrole.Cap on SHS stanchionwith welds blendedTipped and edge polished8-13.52 toughened orlaminated toughenedglass (dependent uponAS1170 load, spanand glasslocation)designEStructural floorsurfaceSHS end-cap weldedand polished smooth1D2A2BMin 180C4Figure 1.

Glass panelssupporting an interlinking handrailcantilever from an appropriate floorfixing.HOf particular importance in theinitial design stage, it is criticalto maintain an awareness ofthe designation of glass panelsas structural or infill, and theclassification of handrail as loadsupporting, non-load-supporting,or interlinking. Combined withother considerations (e.g. whetheror not mechanical point-fixingsare specified, span is cantileveredor supported on both sides),this determines the grade ofglass (e.g. laminated annealed,toughened safety, laminatedtoughened) and type of handrailthat satisfies the code.C4GAs in other aspects of stairand balustrade design, Ardenwill advise with respect to thepracticability of preliminarydesigns with respect to Australianstandards.Semi-framed lateral channel.

Design, construction and installationC4design noteFor all commercial applications, it is important that sufficient spacefor the stairwell cavity be allowed to satisfy Australian Standardsand BCA requirements.The footprint is primarily driven by the floor to floor rise, as well as thestaircase configuration chosen. However, stringer and balustrade style designmay increase the amount of space required. Allowing too small a cavity canrestrict the design options of the staircase. Also, points at where the staircaseinteracts with other structures are best addressed early in the design cycle.Consultation with Arden early on will help ensure that these design issuescan be addressed in a cost-effective manner.Stainless SHS stanchions with glass infill and offset handrailinfill glass panelsAbout this documentIntellectual property is copyright ArchstairsPty Ltd unless otherwise agreed in writing.
