Conex/shipping container builds?

[Retlaw 66]

Looking for some tips, A search here didn't turn up much.
I just picked up a 40' high cube container to add extra space to my 32x50 pole barn. Plan to add a roll-up door in one end for access to both ends, hang some led lights and an outlet or two, and some over head shelves.
Plan to use it for tractor storage, but these things are so easy to buy/place, I'm thinking of getting a few more for dedicated work areas.... sand blast area, paint booth, wood shop, etc. The possibilities are endless.

For the roll up door install, there are some great vids on YouTube. Menards has a 6'x7' for $250 but no stores in my area. I'm at $400 from a garage door company, and still looking for a better deal.
Unsure how I will attach lights/conduit to the interior surfaces without welding, but may have to go that route, it'll just require paint repair afterwards.
There are hangers in the upper corners every 54" or so. I've seen shelf brackets attached to those. I may do something similar.
Any tips to accomplish my goals?

You could weld your supports but it isn't my first choice. I installed deep unistrut every 5ft width wize. I used 90 degree two hole angle brackets to attach these to the side supports and sealed the penetrations. This gave me a trapeze to support my utility lines and mount 4ft fixture perpendicular to the length. I'll grab you a pic later.

When I was shopping for my shop materials one of the local truss manufactures was making a truss kit to span two cans and leave an open area between. Looked to be a neat setup to me if one was looking to get area under a roof. I've also seen a similar setup here on GJ.

no neat sig line.

I've seen that also. It did look like a good use of space!

Hey LX,
I went with the Unistrut suggestion. Picked up some 10 ft lengths of the 1-5/8" square from the local electrical supply for $12.67 each.... that beats HD by a good amount.
I put the uprights up against the wall and will be using some 1/2" x 6" J-hooks to secure to the existing D rings in the upper corners, and at the bottom corner. Cross piece on the ceiling will sit on top of the uprights, and attached with the 4 hole 90 degree brackets. It'll be self-supporting but use the D hooks to hold it in place.
It got cold and dark, but took a few pics of the upper attachment(s). In addition to the J-hook, I also tried a modified eye hook, and a cable clamp. The J-hook fits the best.

I'm reconsidering the roll-up door. I looked at some roll-up doors at a local storage warehouse and was concerned about the gaps in the guides which mice could likely get thru. They don't seem very wind/water tight either.
I may just build a pair of doors using square tubing for a frame and use the end panel for the sheeting. It'll be more work but will produce a much more solid door(s).

Ultimately, I would like two containers with a roof spanning them. Maybe even a second floor. Suppose I should check with the township before starting that build!

That's a different way of doing it I hadn't thought of, very cool since there's no penetrations. Also I'm not sure what roll up doors you've been looking at but mine seal tight enough I'm not too worried about rodents.
