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.

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'. 

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.  

UNEX has designed its Arena range to comply with the B1, B2, F2 and F4 requirements of the NZ Building Code and are suitable for occupancy types 'A', 'B', 'E' and 'C3' in accordance with AS/NZS 1170.

Producer statements for all standard specifications can be created online in the registered area of the UNEX website.

For non-standard situations not covered by UNEX's specifications, a site-specific PS1 and specification may be prepared by UNEX upon request.

UNEX has specialised in designing and manufacturing architectural balustrade systems throughout Australasia and beyond since 1981.  

This Metropolis Frameless Glass Style has been incorporated in UNEX's range since 2006 and was one of the first frameless systems with mechanical fixings on the NZ market. This system has since been used in numerous projects throughout New Zealand including high rise towers, residential apartments, pool fences, etc.
