Horizontal Safa-Slat Balustrade

The Unex Systems’ Aluminium Horizontal Safa-Slat style features horizontal slats, a single top rail and a choice of top rail profiles - all of which can be finished in a range of colours.  

This system is great for situations where privacy is an issue, commonly adapted to use as screens and as a deck fascia that fixes between the balustrade posts that is used in conjunction with the other Unex Systems balustrade styles.

Key Features

  • Wide range of finish options – can be powder coated or anodised in all standard NZ colours
  • Standard specifications available for top or side fixing to both timber and concrete
  • Specifications for non-standard situations may be provided by Unex Systems upon request
  • Screws together with minimal, if any, welds required
  • Made from 6000 series extruded aluminium alloys
  • Installed only by Authorised Fabricators, available nationwide
  • Standard horizontal slats are 50mm H x 16mm W
  • Post option available for side-fixed situations to conceal screw fixings
  • Designed for wind speeds up to 64m/s (ULS)
  • Range of six plus top rails to choose from
Scope of Use

These horizontal safa slat styles by Unex Systems can be used for both external and internal applications, including decks, balconies, stairways and landings, mezzanine floors, screens and pedestrian gates, etc. 

It is ideal for standard height balustrades where privacy from lower areas is required, apartment dividers, as well as screens for patios, back of barbeques and higher wind areas.

Unex Systems’ balustrade brands – namely Aluma, Eclipse Vogue and Arena – are designed to and comply 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 wide range of fixing options available to fix to the top and sides of both timber and concrete substrates. The Unex Systems DKG2 gutter bracket system is designed for membrane decks with gutters and waterproofing considerations. Site-specific specifications may also be provided upon request for those non-standard situations.

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

Limitations on Use

The Unex Systems brands designed for residential situations, office and work areas, as well as for areas with moving people – namely Aluma, Eclipse Vogue and Arena – 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.

The standard Unex Systems’ 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”.

Where a top rail of a balustrade on a stairway does not comply with D1/AS1, Unex Systems recommends an auxiliary complying handrail mounted to the side of the balustrade posts.

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. 

Statement of Building Code Compliance

Unex Systems has designed its range of balustrade styles in the Aluma, Eclipse Vogue and Arena brands to comply with the B1, B2, E2 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.

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

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.

In-Service History

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

This “Safa-Slat” style was designed and incorporated into the Unex Systems range in 2010, in response to the need for privacy and shelter, as well as meeting full balustrade load requirements. It has since been used in numerous projects around New Zealand.
