Good Neighbour

Stratco Neighbourhood Fencing oers a complete range of steel
fencing products and accessories. With a choice of colours, styles and
options a look can be achieved to suit your home and environment.
Good Neighbour products are designed, manufactured and priced
to t your lifestyle. Choose from a variety of roll formed steel
fence sheets that t simply into specically designed tracks and
posts, which have been engineered for strength and designed
for good looks. All materials are manufactured to length, making
installation a breeze and reducing waste. Standard panel heights
are 1200mm, 1500mm and 1800mm. For the optional screen top
panels add a further 300mm.
SMARTSPAN
Smartspan is commonly used as industrial wall cladding and for
roong applications that require a long span. However, its inherent
strength and appearance make it a smart choice for fencing.
Smartspan will stand the test of time, while oering bold, attractive
lines to neighbours on both sides.
CGI MINI
CGI mini is a high fashion steel prole that is equally suited to
traditional or ultra-modern homes and gardens. With countless
applications including Good Neighbour fencing, its mini corrugated
prole provides a distinctive appearance to neighbours on either
side of the fence. CGI Mini may not be available in all states, check with your local
Stratco store for availability.
SUPERDEK
As a high tensile, steel prole sheet, Superdek is suitable for fencing
applications because of its strength and its modern good looking
appearance. The Superdek prole has been the number one fence
sheet choice for Good Neighbour fencing for many years and will be
around for many more.
SCREEN TOP
The UV treated, plastic lattice screen top is available as an option
with your new fence or as a 300mm extension to your existing Good
Neighbour fence. It comes in a range of colours and is an attractive
and durable way to add privacy and security while allowing the light
to lter through.
WAVELOK
Stratco has specically designed the Wavelok prole for fencing. It
has a bold, striking appearance that looks identical on both sides of
the fence. Its distinct owing lines appear similar to fence palings,
they are visually attractive yet provide the strength and security
necessary for fencing.
CGI
Commonly found throughout Australia, CGI is a versatile building
material that has always been popular in domestic fencing. Its
soft owing lines complement both contemporary and colonial
styled homes and make CGI an ideal fence as either a feature or
a backdrop to your garden.

To select the most suitable fence conguration, the design wind
speed at the location where the fence is to be installed is required.
The diagrams to the right show the various congurations 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
conguration 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 nal 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 inll 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
inll inserted on the exposed post end for a clean nish.

The tables below provide maximum wind speeds for non-cyclonic and cyclonic regions. For cyclonic areas, the only suitable cladding is
Superdek, Smartspan and Wavelok. Fences with no free ends, or with internal sections that are further than two panels from a free end, can
be designed using the maximum wind speed for tapered ends. Corners or openings with solid gates are not classed as a free end. If you are
unsure of your wind speed refer to the “Determining Wind Speed” brochure.
Footings
The sizes of post footings are dependant on the wind speed, soil type and the height of the fence. The following tables can be used to select
the correct footing. Footings shall be founded in natural soil only. Concrete shall have a minimum 28 day characteristic strength of 20MPa
(Grade 20). The top of the concrete should be shaped to direct water away from the posts. For the three footings adjacent to a free end and
posts supporting a gate, the footing size will need to be increased in depth by 100mm. All posts are to be embedded at least 500mm into
the footing.

Good Neighbour components are displayed in the gure below,
some components are optional and not required in all congurations.
The top and bottom tracks are xed to the posts using 10x16mm
self drilling screws on both sides. Posts are xed together using
10x16mm self drilling screws at a maximum spacing of 600mm
and no further than 100mm from the top or bottom of each post.
CGI Mini panels need a 38x25mm internal rail, xed to the posts.
Fencing in wind speeds of W41 and higher in both cyclonic and
non-cyclonic areas, need the sheets to be xed to the top and
bottom tracks at the overlaps with 10x16mm self drilling screws.
It is recommended that the sheets also be joined mid span at
Gates are available in single format for pedestrian access or double
format for vehicle access and can be optioned with or without the
Good Neighbour screen top. Single gates are 820mm wide and
are commonly xed to 50mm SHS posts, with an 845mm opening.
Double gates are 3220mm wide and are commonly xed to 65mm
SHS posts, with a 3255mm opening. Gates come pre-assembled
and are provided with hinges, latches and catches. Accessories
such as pad bolts and drop bolts are optional extras.
Posts are supplied 545mm longer than the height of the fence.

Fencing should not be located within 1000m of a marine environment or in severe
industrial or corrosive environments. For more information refer to the ‘Selection, Use
and Maintenance of Stratco Steel Products’ Brochure.
Stratco does not accept liability for any loss or damage suered as a result of any errors
in the interpretation or application of this design guide. Any person wishing to check
any calculations made by them pursuant to this method may wish to seek independent
engineering advice.
EXAMPLE
Design wind speeds have been determined in accordance with AS1170.2-2002 and
AS4055-1992 allowing for a design return period of 25 years.
This method has been developed by Stratco with the assistance of suitably qualified en-
gineers to comply with the requirements of the above standards.
It is assumed that the soil is natural and in a relatively undisturbed state.
You intend to construct a fence around the boundary of your property. You want to build
a 2100mm high screen top fence with Wavelok cladding. The first step is to work out the
wind speed for your area. By referring to the ‘Determining Wind Speed’ brochure, you
calculate your wind speed is W33.
You determine that the free ends need to be either a three sheet tapered panel or a two
sheet panel that is not tapered by refering to Table 1.3. The internal panels on the rest
of the fence can be standard three sheet panels. The corners need no special treatment.
Using the post spacings in Table 2.0 you can calculate the required number of panels.
Assuming that you intend to use tapered panels on both free ends, all of the post spac-
ings are 2350mm.
From these figures you calculate that the 35 metre sides will require 15 panels, and the
20 metre rear side will need nine panels, making a total of 39 panels.
