Roll-up doors go together with containers like peanut butter and jelly. Containers come with two swing doors on one short end of the container, but often that simply isn't enough. Many people need to access the container from multiple points or don't want to deal with tight container doors that can sometimes require a bit of strength to open or close. (Although if you're having problems with that, check out our hints from this post.) One easy solution is to add a roll-up door onto the container.
Roll-up doors come in various widths - 4', 5', 6', 7', 8', 9' wide. They can be made to fit a standard 8'6" high standard container or a 9'6" high-cube container. This means there is pretty much a door to fit whatever you want to do with the container. One popular spot to put a container is in the opposite end of the container from the container doors. This allows access from either end, so nothing is too far from the door. Also, the corner posts make a great foundation for putting the door tracks onto the container.
We have roll-up door kits so you can add a roll-up door on your own. We also can add roll-ups in various shops we have located throughout the US.
Here are some pictures of roll-up doors to show you some possibilities.
