Hydraulic door trusses can be internal or external trusses - 39

With Schweiss hydraulic doors you always have a choice. That holds true for trusses on hydraulic doors too. They are available as a standard external truss on the outside of the hydraulic door, or we can offer it as an internal truss on the inside of your hydraulic door. On smaller doors a “no-truss” option is also available. Schweiss hydraulic doors are pre-built with a special standard bottom truss that provides added strength and rigidity, very important in high wind conditions and to keep the doors weathertight under all conditions. The external truss is located on the outside of the one-piece hydraulic door frame three inches off the floor/ground level. We paint the exterior steel truss because it is exposed to weather elements. Schweiss Doors also offers custom-painted or custom designed external trusses to match your building, hangar or building structure; we can custom enclosed and flash the external truss to give it a neat appearance; and we can raise the external truss higher than the standard 3 inches off the floor/ground which helps to keep people, equipment, debris and snow away from the bottom truss. You can eliminate some minor hassles with an internal truss, it gets placed on the inside of the hydraulic doorframe. Advantages to the internal truss is it gives a nice clean look to the exterior of your door, it allows for better drainage to a opened door and will not collect snow when open and when closed, it’s one less thing for your snowplow to run into. It’s located and protected from outside weather elements and does not act as a catch-all for leaves, dirt and grime. When the door is in the open position the internal truss will protrude into your clear opening and you will lose some headroom unless you mount your door higher. The one-piece doorframe in itself will have properly sized members to provide the necessary support for additional strength. On small size hydraulic doors the “No Truss Look” gains valuable headroom and gives you the clean look both outside and inside the doorframe. Simplicity, quality and strength are standard on every “One Piece” hydraulic door from Schweiss. Schweiss is the Number 1 builder of hydraulic doors for all buildings.
