New One-Piece® Hydraulic Doors
Schweiss Doors is proud of our new One-Piece® hydraulic doors that swing out requiring no headroom. Already a leader in the bifold door industry, we at Schweiss Doors continue to bring new quality products to customers with the introduction of the hydraulic One-Piece® door. The door design requires zero headroom, comes prehung, is watertight, easy to install, easy to operate with the push of a button, easy to insulate and swings out to provide a canopy when the door is in the open position.

Simple Unique Design
Powered by a powerful hydraulic pump, two heavy-duty cylinders activate the One-Piece® hydraulic doorframe. The single panel doors have one set of hinges across the top of the door frame. When the door is being opened the hinges allow the door frame to swing out and away from the building to the full open position which forms a canopy. The hydraulic pump can be conveniently located away from the door opening to keep the clean look.

Lose No headroom
Schweiss One-Piece® Hydraulic Doors require no headroom loss, so retrofitting to existing structures such, can help you gain additional overhead clearance required to utilize your steel or wood structure's full clear opening. This is a real money saver!

The One-Piece® Hydraulic Door design is another alternative to the bifold door. Schweiss, the leader of the door industry, offers customers choices when it comes selecting doors for their structures / buildings. Please read the following literature and let it be a helpful guide to selecting the door of your choice to accommodate your structure / building with the intention of getting the most for your dollar with the best design money can buy.

Hydraulic Door Frame

  • Each Door comes prehung with frame.
  • One Piece doorframe is manufactured out of 2x4 tube.
  • Vertical doorframe members are 2x4 tubing
    (Schweiss does not use C-Channels).
  • Pre-assembled, pre-welded and delivered prehung within its frame for ease of installation.
  • Bolted frame connections for shipping, no welding, easy to install (Schweiss does not use tec screws for frame connections).

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.
