The systems are designed to comply with the Building Code of Australia and the relevant Australian/New Zealand Standards.  These include:

  • AS/NZS 1170: Structural Design Actions
    • Part 0: General Principles
    • Part 1: Permanent, Imposed and Other Activities
    • Part 2: Wind Actions
  • AS 1288: Glass in Buildings
  • AS/NZS 1664: Aluminium Structures
  • AS 1926.1: Swimming Pool Safety - Safety Barriers
  • AS 4100: Steel Structures
  • AS/NZS 4673: Cold Formed Stainless Steel Structures

In particular AS/NZS 1170.1 Table 3.3 specifies design loads for balustrades and barriers on balconies etc.  These can be divided into three categories:

Type C3 - Private (Domestic) areas with loads of 0.75kN/m horizontally on the rail or 1 kPa infill load on the panels.  All the balustrade systems satisfy this loading.

Type C1/C2 - General Public Access areas with fixed seating.  Loadings are 1.5 kN/m horizontally on the rail or 1.5 kPa infill load on the panels. The Harkk VIEW, EDGE 86 and RECT 86 systems are recommended for this type of area.

Type C5 - Areas subject to overcrowding such as shopping malls, bars, etc.  Loadings are 3kN/m horizontally.  The RECT 86 and VIEW systems are recommended for these areas.

AS/NZS 1170.2 specifies wind loads for different regions and building configurations.  Depending on rail height and post spacing selected, one or more systems may satisfy the requirements for any area and situation.

Loadings for Pool Fencing is generally less than the comparable loading for a similar balustrade situation.

The Bifold system, using the RECT 86 post and VOID rail over, has been designed to accommodate wind loadings up to 3 kPa.
