Accurately determine where the fence runs. (In some cases a
Surveyor may be required) and mark the position using a temporary
string line. Using the spacing information from the design
guide and the table below mark the post positions of the posts.

It may be necessary to use a shorter panel to obtain the required
fence run and for better aesthetics this shorter panel should be
positioned adjacent to a corner or gate post. Once marked, the
post holes can be dug. The use of a manual or mechanical auger
is recommended, especially for harder clay soils. The footing
dimensions can be found in the design guide. However, the last
three holes near a free end and for posts supporting a gate will
need to be 100mm deeper than the standard depth specified in
the design guide.
INSTALLATION OF GATES
The gate post holes should have already been dug. Fix the hinges
to the gate using the screws provided. Two hinges are required
per side. Fix the hinges to the SHS gate post, making sure the top
of the post is flush with the top of the gate. If the fence extends
past the gate, the post for the adjacent panel should be fixed to
the SHS gate post.
Once the gate and posts are assembled, place the gate in position.
Chock up the centre of the gate with wooden blocks while using
a plumb line so that the post is between 8mm and 14mm off
vertical. This allows for the deflections under the weight of the
gate. With the gate propped the posts can be concreted into place.
Preparing footings
Once the post has been positioned and propped into place,
the concrete can be mixed and poured. Prepare the Stratco
concrete mix as per the details on the bag and fill the hole with
approximately 150mm of concrete. Using a shovel or pole agitate
the concrete to remove air pockets. Add a further 150mm and
agitate again. This process should be repeated until the hole is
full. The top of the footing will need to be smoothed with a trowel
ensuring the surface slopes away from the post. No load should
be applied to the footing for at least 48 hours. Maximum concrete
strength may not occur for up to 28 days, so care should be taken
not to apply excessive force to the fence during this time.
