In this blog, we’re going to tell you how you can build a sectional doors for your property.

Measure around where your sectional garage door is going to be fitted

First, you’ll need to know the exact width and height of the opening you’re going to be building a door for. Then, divide the height measurements you’ve taken by the number of panels you’re going to use in your door.

Although sectional garage doors only need around 250mm headroom, you’ll need to make sure you have this much space to play with in your garage before getting down to work.

Cutting the panels

Cut your panels according to the dimensions you’ve noted down – sectional garage door panels can be made from a wide variety of materials. Wood, aluminium, steel, glass and vinyl are among the most common.

Take the width of the door you’ve measured and subtract two or five centimetres. You’ll then need to cut two pieces of 1½-by-2-inch wood studs to this new width. Repeat the process for the height: again, take 5cm from the original measurement for your wood studs. Place between the width pieces in order to create a rectangular frame and nail and glue together.

Repeat this process for the other panels you’re making.


Cut three sheets of plywood and fit to the frames you have created in the previous step. Then, nail a roller to the top and bottom of the shorter side of each panel, so each panel should have four rollers. Roll the panels on to the track and screw the hinges in when the panels are in the closed position – for example, when they are on top of each other.

Attach the panels to each other and there you have it: a complete guide to building a sectional garage door. If you have any questions about the process, don’t hesitate to ask the friendly and professional Door Systems Australia team.
