Structural question

[67Stang5.0]

I have a 36X40 metal building that has the sliding type implement doors and I want to put in a roll up door so I can better seal the building. The problem is when the building was built it doesn't seem like there was any rhyme or reason to the spacing of the vertical support beams. The issue is one door opening is 7', one is 9' and the space in between is 9'. I think I need a wider door than 9'. So, do I need a wider door on a building that is going to be a shop for working on cars? If so, how can I go about making one of the openings wider? All the vertical supports were sunk in the ground before the pad was poured. Any advice will be appreciated. Thanks in advance.

Welcome to the forum!

Some pics would help to understand exactly what you're working with.

Hi, if your wanting to widen doorway?, u will have to dig pile / or footing (700mm x 700 mm square and deep as until u hit clay then dig to a bell bottom shape to spread load)...have that sealed with a likewise shaped poly liner cut to suit then make up reinforcing to suit, cage-ging the flange plate anchor rods / threaded bolts etc (make sure u level to hite needed and create door sill gradient) .

Make up new steel stud or frame (steel "c" or "i" section)to suit door., the 2 studs should end at top plate of wall and joist at approx height of door.

Also ask door supplier to give frame sizes.

HOTT SCHITT - Thanks! That's what I was thinking along with having to shore up the header along the eave. I had no idea the anchoring of the new verticle would need to be set like that. Looks like I'll figure out how to make what I have work. I hope a 9' opening will work. Thanks again!
