To select the most suitable fence configuration, the design wind
speed at the location where the fence is to be installed is required.
The diagrams to the right show the various configurations of the
Good Neighbour Fence. If you are unsure of the wind speed for
your area, refer to the brochure titled “Determining Wind Speed”.
Once the wind speed is known, using the height of your proposed
fence, Tables 1.0 to 1.4 can be used to determine what fence
configuration is suited to your environment.
Where fences come to an abrupt end, the wind loads are higher
than the rest of the fence and special consideration needs to be
given to these free ends. Options include tapering, using SHS posts
or reducing the number of sheets per panel. The maximum wind
speeds for these various ends are also shown in Tables 1.0 to 1.4.
The free end consideration only applies to the two panels nearest
the free end; the remainder of the fence can be designed as internal
(internal panels are not part of a free end) using the wind speeds for
a tapered end. Corners or openings with solid gates are not classed
as free ends.
Tapering occurs over the final two panels. The two panels come to
a combined height that is two thirds the height of the other internal
fence panels, refer to Figure 1.0.
When choosing a design it is more economical to use three
sheet panels. Two sheet panels are generally used in areas that
have a high wind speed or for designs that require the use of
non-tapered free ends.
To select the number of fence panels and accessories required
a sketch should be drawn and post positions determined. It is
recommended that any short panels be installed adjacent to a
corner, gate or free end. Fence caps and ball caps cannot be used
on SHS posts.
The following methods can be used when designing a fence for sloping ground. To cater for ground fall, sloping and stepping of panels can
be used. The post spacing remains the same as the rest of fence in both options.
Sloped Fence
Sloping is a method used to traverse a slope without causing a break
in the top line of the fence. It is most suited to long continuous
slopes. For up to a two degree slope, fence panels and track lengths
can remain the same. For steeper slopes, longer tracks, sheets and
screen top infill panels will be required.
Stepped Fence
Stepping is ideal for sudden changes in ground height. A longer
post is needed to ensure the footing of the stepped panel is
embedded correctly. If post or ball caps are to be used, both posts
at the position of the step should be the same height and a post
infill inserted on the exposed post end for a clean finish.
