Overview

Installing the infill sheets for a Colorbond fence is relatively easy but you will need someone to help you. This step-by-step guide shows you how to install and secure the top and bottom rails, install the infill sheets, along with how to cut the sheets and posting caps to size.

Steps

1Install the bottom rail

Before you can put the Colorbond panels in place, you will need to install the bottom rail. Insert the rail between the first and second post and use the spirit level to make sure it's level. Once its level, use the cordless drill to screw through the post and into the bottom rail to secure it.

2Insert the first panel

This where you will need someone to help you. Always follow the instructions and install one Colorbond panel at a time. Starting at one corner, insert the bottom of the panel near the end post, tip it onto an angle and then push it down into the bottom rail. Slide the panel back, so that it's flush with the post.  

3Insert the top rail into the first panel

Slide the top rail, between the two first and second posts so that it secures the first panel. Push the corrugations on the Colorbond panel into the top rail but leave the last corrugation free, so that the next panel can be secured to it.

4Insert the other panels

Follow the same procedure to insert the next panel. Insert the lower end of the panel first, so that its first corrugation overlaps with the last corrugation on the first panel.  Push the second panel into the bottom rail. Push the top rail down to secure the second panel. Insert the final panel, the same way.

5Secure the top rail

After installing of the Colorbond panels in the first section of fencing, push the top rail down to secure them. Use the spirit level to make sure the top rail is level. Once level, use the cordless drill and screws to secure the top rail by drilling through the posts at either end of the panels. 

6Install the other Colorbond panels

Repeat the previous steps to install the bottom rail, the infill panels and the top rail until you have completed the large sections of the Colorbond fence.

7Cut an infill panel to fit

If you need to cut a Colorbond panel to fit, measure the distance between the two posts. Mark this distance at the top and bottom of the Colorbond panel and use the spirit level to draw a straight line between them.

8Cut the panel

Put on the safety glasses, gloves and ear muffs and use the angle grinder to cut the panel along the line you marked.

9Measure and cut the top and bottom rails

Using the measurements from the infill panel that you cut, measure and mark them onto a rail for the top and bottom of the fence. Clamp the rail onto the saw horse and use the angle grinder to cut the two rails to the right length.

10Insert the last panel

Slide the bottom rail between the two posts. Make sure it's level and secure it with the cordless drill and screws. Insert the last panel. Secure it using the top rail. Check that the top rail is level. Use the cordless drill and screws to secure it to the posts.

11Fit the caps to the post

To finish the fence off, fits the caps by pushing them onto the posts. For half posts, use the tin snips to cut either side of a full cap and snap it in half. Fit these half-caps on top of the half posts at either end of the fence.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
