All Schweiss hydraulic doors are factory welded and made of structural steel tubing. The doors are hinged horizontally at the top of the frame using heavy-duty hinges by each upright tube on the doorframe, which evenly distributes the load onto your door, building, truss and header. Hinges are pre-located at the factory to align with the building and truss members. The door swings outward, away from the building. In the open position, the door will be laying flat at 90'°. Doors are trussed to provide extra strength. Extra metal in the right places reduces bowing or sagging when the door is open or closed. Each door is fully assembled from the factory, saving you hours of installation time.
