Unex’s Extreme Barrier styles have two ranges — X1500 Series and X3000 Series.  

• X1500 Series is designed to meet classifications C1/C2 and D of AS/NZS 1170.1, which stipulates a 1.5kN/m load on the top edge — twice the load required on a typical residential application.
• X3000 Series is designed to meet classifications C5 of AS/NZS 1170.1 which stipulates a 3.0kN/m load on the top edge — four times the load required on a typical residential application.

The Extreme Framed Baluster Barriers are typically used for, but not limited to:

• Grandstands
• Gymnasiums
• Surf clubs
• Shopping centres
• Restaurants
• Bars
• Sports clubs
• School halls
• Cafes
• Public pavilions  

Extreme Barriers are also suited to other situations where large post spacings, a bulkier look, or additional height is required.

There is a wide range of fixing options available for both suits to fix to steel, timber and concrete applications. Site-specific specifications may also be provided upon request for those non-standard situations.

The standard powders used by Unex Systems (Interpon) can be used right down to sea level, provided the care and maintenance instructions are adhered to.

Unex's ‘Extreme Barriers’ Range is designed to meet the loading classifications of AS/NZS1170.1 of the New Zealand Building Code and is therefore not applicable to the requirements of the transport code. This design is not suitable for applications such as a vehicle barrier.

Typically Extreme Barriers are not suitable for top-mounting to timber.  

For certain buildings, such as some industrial situations, a higher grade powder coat powder must be specified.  

UNEX has designed its Extreme Barriers range to comply with the B1, B2, F2, F4 and F9 requirements of the NZ Building Code and are suitable for occupancy types 'C1/C2', 'C5' and 'D' in accordance with AS/NZS 1170.1: 2002.

For more information, please refer to the “NZ Building Code Compliance” document (right).

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 specialises in designing and manufacturing architectural balustrade systems throughout Australasia having done so since 1981.

These Extreme Barriers have been incorporated in Unex Systems’ range since 2012 — designed in response to the needs of the market place for pre-engineered barriers designed to meet the extremely heavy live load classes 'C1/C2', 'C5' and 'D' of AS/NZS1170.1:2002. It has since been used in a number of jobs right throughout New Zealand.
