Scope of Use

The “Panorama Top-Mount Channel” by Unex Systems can be used for both external and internal applications, including decks, balconies, stairways and landings 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

The Unex Systems Arena brand is designed for residential situations, office and work areas, as well as for areas with moving people, but cannot be used for “C1/C2”, “C5” or “D” Loadings.  

In these applications, Unex Systems recommends the use of the "Extreme Barriers" range which has been specifically developed for these higher loadings in crowd and public situations.  

There are certain risks to consumers associated with glass balustrades where no other form of top rail exists. Refer to “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.  

Statement of Building Code Compliance

Unex Systems 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 Systems website.

For non-standard situations not covered by our specifications, a site-specific PS1 and specification may be prepared by Unex Systems upon request.
