Garage door hangers

[gogolf0401]

I have my garage door up and the hangers are fastened to the bottom of a truss. I'm putting up steel on the ceiling now and am wondering what is the best way to deal with the door hangers. Cut the steel around them or remove them and put them on top of the steel once it's installed.
I figure with the corrugated steel panel I wouldn't be able to tighten down the hangers to the truss since it might squash the steel a bit.

What'd you guys do?

In my shop, I hung a plumb bob from each lag screw in the trusses and marked the centerline of each hole on the floor.

Once the tin was up, I reverse plumb bob'd the location back to the ceiling and drilled holes through the tin, which worked OK.

A laser level with the vertical beam function would work, too.

FYI, the ribs in my tin ran parallel to the trusses, so I did not cross any ribs.

In your case, I'd make spacers, that are slightly taller than the height of the ribs, and use longer lag screws to make up the additional length.

Do not lag the angle brackets down against the tops of the ribs!

I used 3/4 conduit and did angle support in attic.

I welded up my own brackets out of angle

Not for a metal ceiling, but here is my design.

I measured where my existing hangers were located and built new ones out of that multi hole angle stuff that went on the flat between the ribs. Also stretched a 2x6 backer between the trusses to give me a little wiggle room on the mount. remember if you ever plan on adding an opener put a backer in for that before your tin.
A drywall lift worked great for those 16" sheets (the side I did the ceiling in was only 9' high)

Spacer painted the same color as the tin. Cutting holes in tin is kind of a pain. Never really looks "finished".
