How to Install Colorbond Fence

Consult with neighbor and come to agreement that the fence requires replacing.

Get contractors to quote for the work if you don't plan on doing it yourself.

If you do think you can erect your own fence:

Inspect the site were the fence will be installed. Things like - Length, Height required, Slope,Trees, roots, Ground, and consider colour. You may need to have the boundary surveyed.

Purchase the materials. There are many suppliers and prices vary. Also, not all metal fencing is Colorbond steel. Some is imported.

Ensure you have the tools. See list below.

Remove the old fence and clear and level the fence line.

Run a string line at about 150mm above the ground along the fence line.

Screw the colorbond posts together. make sure you leave two apart for the end posts.

Dig a hole approx 600mm deep x 200mm x 200mm at one end.

Drop an end post in.

Push a bottom rail into the end post and dig your next hole.

Drop in the next post.

Repeat all the way to the other end. (You may need to cut a rail to adjust the length).

You now should have a post in each hole. No concrete yet. And the fence bottom rails should all be in.

Using dry Rapid Set or Kwik set concrete half fill each end hole to steady the end posts.

Support the end posts with a top rail pushed into each end post at a 45 deg with one end in on the ground. This supports the post when you run the top string.

run a string from each end post across the top centre of each end post. Make it real tight.

Measure 1820 mm approx down from the string to the ground.

Adjust the end posts as required. Up and down until the top string clears the ground by 1820 mm for the full length of the fence. (To check your level if it is a dead straight fence - stand back about 4 meters and line the string up on the brickwork of a close house with your eye, this works well).

All holes will have 2 x 20kg bags of Rapid set.Add water as you fill the holes with concrete.

Now fully concrete the end posts.

Make your way along the fence concreting each post. Line up close to final position before adding concrete. They will start lower than the top string. Lift them up after you tip in some concrete. The centre top of the post should just touch the string.

Now all the posts are done screw the top rails on for the full length.

Now screw the bottom rails at 1810 mm or 1800 mm depending on your sheet length.

Unscrew one end of each rail.

Insert sheets one by one. Pop in your first sheet and drop the rail down on it. Slide it all the way into the post. lift the top rail enough to get the next sheet in and then move the top rail down again until the last sheet just fits in were it will overlap. Insert the last sheet and push the top rail back down so the screw can be re-installed.

Continue for the full length.

Fit screws to other side if required. (strong wind area)
