Scope of Use

The Metropolis Frameless Glass Style by UNEX can be used for both external and internal applications, including decks, balconies, stairways and landings, mezzanine floors, pedestrian gates, and pool fences, etc.

Unex Systems’ Arena brand is designed to and complies with “A”, “B, E” and “C3” loadings of AS/NZS 1170.1:2002 for residential applications, office, and work areas, as well as areas for moving people without obstacles.

There is a number of standard fixing options available to fix to the top of dry/membrane timber (with water-proofing considerations), wet/open timber, and concrete substrates. Site-specific specifications may also be provided upon request for those non-standard situations.

The standard powders used by Unex Systems – the Interpon powder coat range - can be used right down to sea level, provided the care and maintenance instructions are adhered to.

Limitations on Use

UNEX designs for residential situations, office, and work areas, as well as for areas with moving people, however, cannot be used for “C1/C2”, “C5” or “D” Loadings. In these applications, UNEX recommends the use of its “Extreme Barriers” range of styles which has been specifically developed for these higher loadings in crowd and public situations.  

The standard UNEX top rails comply with the handrail profile requirements of D1/AS1 for “Private” and “Common” stairways (with the exception of the #ARC and #ART top rails), but do not comply for “Accessible Stairways or Ramps”. 

There are certain risks to consumers associated with glass balustrades where no other form of top rail exists. Refer to the “Glass Requirements” sheet (available for download on the right) and in particular, the “Risk to Consumers” section, for further information and to make an informed decision.

For certain buildings such as architectural sky rises (over 3 stories high), light commercial, and high pollution areas, a higher grade powder coat powder must be specified.
