Hinges – Composite or Steel

Composite hinges require no lubrication or maintenance and operate extremely quietly. They are suitable for steel or wooden garage doors and may be mounted using flanged-head screws in wood – and rivets in steel.

Steel hinges are also suitable for both steel and wooden doors – and are included in the hardware boxes as a spare part. Each hinge is numbered so that in the event of a replacement being required, the correct hinge is to be used – as each hinge is designed to fit a specific place on the door.


The rollers for the door panels are made of Nylon. Each is fitted with a ten-ball bearing and steel shaft. Heavy duty and very quiet running, our rollers are pre-packed in every hardware box, but are also available as separate items.

Composite Curves

The curve that joins the vertical and horizontal tracks is also available as a separate item if spares are required. Two composite curves are included in every hardware box. They are multi-directional, so each curve can be used on either the left or right track. Digidoor curves are made from a composite material consisting of glass filled Nylon, which ensures silent running across joins and are available in 12 and 15 inch sizes.

Torsion and Tension Springs

These springs are used on a wide variety of garage doors, from standard singles to caravan doubles. The most important aspect of fitting the correct springs to a door is to ensure the installer is aware of the correct weight of the door, as well as the correct width and height.

Digidoor springs are manufactured to stringent quality standards in our factory and are tested to withstand at least 15,000 operations.
