lighten up the door

[DVerbarg]

Don't know too much about pole barns (know what I don't know /w3tcompact/icons/wink.gif) but do know that my parent's pole barn has doors that are 16' tall and 12' wide. The doors are framed with some type of galvanized metal framing material. Looks to be engineered a little heavier/stiffer then typical metal 2x4s used in housing. I would assume that this material would be available any any pole building material outlet. These doors roll pretty easily and the tracks have not sagged at all over the past 4 years.

If no one else knows what I am referring to I can borrow my brother's digital camera and post a pic.
