If your container does not have a lock box, then any lock with the right dimensions will fit. Just ensure the shackle is not thicker than the hole you're putting it through, and that the clearances and large enough once the padlock is shut.
If you do have a lock box then a square / shutter padlock will be best since you can put it up inside and slide the bolt in place. You can't do with that a normal padlock. That said, the ABUS Granit locks have a special removable shackle for that very purpose, so you install the shackle first, then slide the padlock onto its shackle once in place.
