max. clear width [mm]3,500
max. clear height [mm]3,000

Dimensions for garages with limited height

For garages with low lintel heights, heroal has developed the heroal OD 75 overhead door. A slightly wider slat with a coverage width of 75 mm and a nominal thickness of 20 mm is used in overhead doors with a centre or side-mounted drive. The garage door runs reliably along a guide rail installed directly under the ceiling. In combination with a side-mounted drive, a lintel height of 65 mm is sufficient for installing your heroal roller garage door. Larger garage doors up to 4x4 m can use a centre-mounted drive provided a minimum lintel requirement of just 135 mm. The OD 75 overhead door can be used for installations with following maximum dimensions:

max. clear width [mm]4,000
max. clear height [mm]4,000
max. area [m²]16.0
min. clearance height [mm]2,000
min. clearance width [mm]2,000
min. lintel height [mm]135

Our garage door lexicon

Here is an explanation of the most common terms that come up in the context of garage door sizes.

Barrel diameter The barrel diameter is the diameter of the roller shutters when wound up; this determines the required box size.
Coverage width The visible height of the roller garage door slat when the roller garage door is closed.
Vertical clearance Vertical clearance refers to the clear height of the element minus the encroachment of the shutter curtain in the guide rails. The encroachment should be at least as wide as the slats that are used.
Clearance width The clearance width or clear width refers to the distance from wall to wall in the building opening. The element opening refers to the distance between the garage door's guide rails. If they are installed on the wall, the clear width of the building opening corresponds to that of the element opening. If the roller garage door is installed in the soffit, the clear width of the element opening corresponds to the building opening minus 2x the size of the guide rail.
Clearance height This refers to the free vertical space, i.e. the distance from edge to edge.
Nominal thickness The nominal thickness is the visible thickness of a roller garage door slat.
Roll-formed In the production of roller garage door slats, a roller is used to bring an aluminium strip into the required shape.
Extruded In the production of roller garage door slats, the raw aluminium is heated and pressed through a mould.
