Extreme Barriers - Public Space Balustrades
UNEX’s Extreme Barrier Balustrades are specifically engineered for high-traffic public spaces that require the highest level of safety and structural performance. Designed to meet or exceed the heavy live-load classes C1/C2, D, and C5 of the NZ Building Code (AS/NZS 1170.1), these robust systems are ideal for applications where crowding and pressure on barriers is expected. From shopping centres and school halls to grandstands and hospitality venues, the Extreme range ensures peace of mind without compromising on clean architectural lines.
The range includes both Framed Baluster and Framed Glass styles. The Framed Baluster configuration features vertical bars that not only meet stringent loading requirements but also offer a practical leaning edge for venues like sports clubs and cafés. The Framed Glass option uses thicker safety glass panels to maintain clear sightlines - ideal for theatres, lounges, or areas overlooking events.
Installed by UNEX’s authorised nationwide fabricator network, these balustrades deliver proven durability and superior strength. Powder-coated in any Dulux finish and supported by full PS1 documentation, CAD files, and fixing specifications, the Extreme range is the go-to solution for specifiers working on public-facing builds where both safety and appearance matter.
