An "Automatic Bi-Fold" door gives you the flexibility to make your door opening a practical width for today's large equipment, truck or airplanes without worrying every time you enter your building with large equipment. Are you going to clear the side columns? Width is no problem with a bi-fold! An older building- with too small of a door opening is almost useless, but you can put your building back to work for you again by going bi-fold. It really sharpens up the appearance of older buildings.

Retrofitting Your Building
If the door would stick
out beyond the roof line,
we can
custom cut the
corners of the
door to keep
your building
looking nice!
If you want to open the
whole end wall of your
building up, we can run
posts
up and above or
add on to your existing
posts to make sure you
won't lose any headroom!
If we are short headroom on
older buildings, we can also
extend your wood or steel
posts and put your header
up and above.
