STEEL BUILDING DETAILS
Schweiss bifold doors can fit any steel buildings, old or new, providing the commercial door that suits your needs.
Ideal floor slope for proper drainage are examples 1 and 2 below.
• There must be a solid base or floor under the door frame to seal.
• The door sets on the face of the side column or building line.
Concrete - Side View
• Concrete must stick out beyond the door side column.
• Concrete floor must be level
• Each door will vary - call factory for details.
T-Hangar Buildings with doors on both sides of the building
What to do!
What can be done to keep water out of the building
• Slope the apron in front away from the building
• Slope the concrete inside of the building
What not to do
1 - No or minimal slope on apron.
2 - Locating the seam directly under the bottom rubber seal of the door.
3 - Allowing water to flow back into the building through a seam/crack.
(This is a result of failure to follow precautions 1 & 2 above)
Important to remember:
• Saw cuts may cause water to flow back into the building.
• The combination of saw cuts and no slope may cause water to flow into the inside of your building.
