Aftermarket Container Parts - Bolt on Lock Box
One of the biggest differences between a new and used shipping container, aside from the obvious paint and condition, is the lack of a lock box. Used shipping containers are designed with the shipping line or container leasing company in mind; while a new (one trip) shipping container is designed with the end user in mind.
Simply put, a lock box is similar to an option for a new car, or an aftermarket container part. Shipping lines and leasing companies are very cost conscious (in normal times, and even more so in these times of economic challenge), and they tend to opt out of having a shipping container lock box installed. The client (shipping line) doesn't want it, and they'd prefer to save the cash for buying more containers.
New, or one trip shipping containers, are designed with the end consumer in mind, and many end users want to have a lock box to make sure their good, supplies, equipment, anything inside of their container, is safe and secure.
If you'd like to make your used shipping container more secure, the best way to do this is to have a lock box installed - either the weld on lock box, or bolt on lock box. To learn more about the differences and your options, check out this article on shipping container parts and lock boxes.
