Sectional Garage Doors are known as the safest and most secure garage door on the market. They come in a wide variety of styles and colours. They are generally made from rolled Australian colourbond steel, though we can also fabricatespecialtyaluminum doors as well for maximum strength and security. The door is usually made up of 4 or 5 panels which have hinges and rollers attached. The door opens on a track system up and overhead, which is all counterweighted with springs custom calculated for each door.
