The doors on used shipping containers are not highly secure as-is. However, with straightforward modification, they can provide excellent protection. Lockboxes, heavy-duty padlocks, inner bolts, crossbar locks, and alarm systems are some of the modifications that APS provides for customized shipping containers
APS has designed lockboxes for all door types, including specially designed lock boxes for circular locks and roll-up doors. Adding a steel lock box to your storage container is an effective deterrent against theft.
Window security bars are also a common security modification that allows for increased natural light while preserving the security of your shipping container.
