Avon balustrade style is designed for, but is not limited to, use in projects within the following scope:

• Can be used on but not limited to, internal and external decks, mezzanines, and stairways.
• Suitability for the occupancy type for part of the building or structure but cannot be used for C5 or F/G.
• Can be used in all wind zones up to and including Extra High. In rare or extreme locations wind reverberation can be caused.
• Building height up to three stories or more.
• Avon balustrade style is custom fabricated to the requirements of each project. Prior to fabrication, the following project selections must be confirmed by the specifier: Balustrade height, top rail profile, lower rail position.
• Can be used in side fixed applications. Specifications allow fixing into concrete, masonry, timber and steel.
• Avon balustrade style is compatible with other features such as gates, handrails and custom aluminium sheets.

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.  

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

Unex Systems has designed its range of balustrade styles to comply with the B1, B2, E2, F2, F4 and F9 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 the specifications, a site-specific PS1 and specification may be prepared by Unex Systems upon request.

Unex Systems has specialised in designing and manufacturing architectural balustrade systems throughout New Zealand since 1981.

These framed glass styles have been incorporated in Unex’s range since the early 1990s. There have been a number of enhancements made since this time — in particular during 2008, when the building code changed to incorporate AS/NZS1170 which meant that the required balustrades loads effectively doubled. Unex Systems then redesigned a number of their balustrade extrusions to ensure these loads were adequately met.
