What are overhead doors?
Overhead doors are closures where the door leaf panels are sandwiched into a rail system fitted in the available space ‘above your head’. There are different types of rail systems (or mountings) which can be used with overhead doors. The choice of mounting will also depend on the building and the space available. Do the rails go straight up (vertical mounting) or must the rails be deflected against the ceiling (low, standard or high mounting) or follow a sloping roof (mounting to follow roofline)? The overhead door system is used for both industrial doors in utility applications and for garage doors as it is extremely popular with house-builders.
The overhead door is currently the most popular industrial door on the market. The door is known by various names such as sectional door, section door or garage door, for example. There are many manufacturers producing this type of door on the market.
