Actually no one with their right mind will install a roll up door on a shipping container that will be used is shipping anything for that matter. Unlike the container cargo doors that built to take some serious abuse, container roll up doors are lightweight and fragile they can be damaged easily.

The majority of our customers ordering storage containers with roll up doors installed usually asks to add some container windows and some with a man door on one side too. which make sense, it's true roll up doors are easy to open and close but at the same time they are not as convenient as a man door for frequent access.

With that being said, preparing the container to take the roll up door is the challenge, and that is were you spend most of your time in installing a container roll up door.
Don't get me wrong with what i am about to say, We have been installing roll up doors for the past 15 years or so.
We have seen some professionals on you tube showing how to install a roll up door on a shipping container, and to be honest we were surprised on how they go about it.
They measure and cut out the door opening and with nothing else done, as cleaning or grinding sharp edges they spot weld the vertical tracks to the container panels, then two guys carry up the door roll and try to bolted to the top brackets while they both on ladders with the door on their shoulders. Mind boggling i till ya.
Another roll up door installation we saw was at local shipping container supplier that do container modifications who invited me to visit and take a look on what they do.
Again don't get me wrong, not trying to bad mouth a competitor here, on the contrary i end up advising them on the what we think is the proper way of installing a roll up door on a shipping container. They took and follow the advice.
Anyways they use to frame the door opening with a steel angle to create a flat surface for the vertical track to set on, the steel angle was skip welded and the gaps were filed with caulking. Which is really a bad idea as the caulking will look good up to the first month maybe. Then it will start deteriorating and leaking.
Whenever we do any container modifications the one thing that's always on hand is steel tubing. All the panels on any shipping container are corrugated and to compensate for that we use steel tubes.
If it is a man door, it's sitting inside a 2 inches by 3 inches steel tube frame, a shipping container window is sitting inside a steel tube frame, even a small 12X12 inches louver vent is sitting inside a 2X2 steel tube frame.
Shipping container roll up doors are no exceptions, they need a steel frame to be installed.
All what's lift is dropping the door in the tracks and add some tension to the spring, too much tension will pull the door up fast and will be hard to close. Too little tension will drop the door fast and will be hard to open. The door tension should be enough when the door can stay in place at half way open.
