Sectional doors are made of separate panels that lift upwards and rest parallel with the garage ceiling. Sectional doors are made up of between three to eight sections fixed together by strong hinges. Castors are fixed to the panel edges allowing the door to move up and down the track system which is fixed to the door frame and roof.

A brief history of the sectional garage door

Although the origins of the Sectional Garage Door can be traced back to some early science journals published in 1906, it is accepted that the first person to design and manufacture overhead sectional garage doors was Mr C.G.Johnson, who started the ‘Johnson’s Overhead Door Company’ in 1921.

As the age of the automobile took off, so did the need for a convenient way for motorists to store their vehicles in a secure garage. In 1926 ‘Johnson’s Overhead Door Company’ took things a step further designing the first electric overhead garage door opener. Unlike today’s wifi enabled sectional garage door motors, back then you needed to push a button on a post to open the door. The first radio controlled remote controls were designed in 1931.

Sectional Garage Doors are designed using a varying number of panels depending on the height and width of the garage door. A standard sectional garage door will have between 4 and 5 panels opening upwards and overhead, using a torsion system to counteract the weight of the door. Over the years sectional garage doors have been designed using many materials, including steel, aluminium, wood and glass.
