MULTIPLE USES
An "Automatic Bifold" 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 bifold! 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 bifold. It really sharpens up the appearance of older buildings.

Opening the entire endwall

Mounting a bifold door on
the sidewall of your
Quonset
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 you are short headroom on
older buildings, we can also
extend your wood or steel
posts and put your header
up and above.

One of our customers,

pictures of a good idea he
had. Mark the clear
opening for any size
plane, using these height
markers on the side
columns.
