To make the independent sections act as a complete door, the sections must be hinged together. Hinges are found on the end stiles and center stiles at the meeting rails. All hinges perform 2 basic functions: 1) with bolts or screws, they join the sections together, and 2) they allow the sections to “break”, independent of each other, as the door travels.


Industrial door

A sectional overhead-type door which is intended for vehicular use at entrances of parking garages, factories and manufacturing plants, normally operated in excess of 5,000 cycles per year.

Inside lock

Spring loaded, sliding deadbolt lock operable only from interior of the door.


Material having the ability to reduce heat or cold transmission. Two popular types are foamed-in-place “polyurethane” and rigid panel “polystyrene”. Sectional steel doors are available with various types of insulation.


Triple contact interlocking joints that block cold air and create thermal breaks between metal door skins to prevent cold or heat transfer. Garaga’s InterlockTM joints stop heat transfer 35% better than the average of its competitors and outperform the competition by a factor of 50 on wind transfer between door sections.
