WHEN OPEN LAY FLAT
The One-Piece® hydraulic door will be at 90° from the building when fully open. External trusses are standard on hydraulic doors. Optional Internal Trusses are available.
SLIGHT SLOPE RECOMMENDED
One-Piece® doors should have a slight downward slope when open to direct moisture and water off the door sheeting. This prevents moisture and water from seeping under the door sheeting and ruining the interior door insulation.
One easy way to get slope on your hydraulic doors is to open the door
to allow your vehicle/machinery in, then lower the door to create a slight slope for moisture to run off.
CAUTION: Remember to open the door again when moving your vehicle/machinery in or out of the building.
OR ORDER THE DOOR WITH A BUILT IN SLOPE !
Request a taller door frame that allows you to open your door to the full clearance while still having a slight slope to the door in the full open position allowing proper drainage .
HAVE A NATURAL SLOPE
Bifold doors have a 1:12 natural slope when in the open position.
The sheetin on bifold doors are flashed to allow water to easily drain off the door.
Water and snow run off in any position!
Internal trusses are Standard. No external truss required on bifolds
