Maritime containers play a pivotal role in transporting and storing goods worldwide. While many people are familiar with the standard 40-foot container, it’s important to understand that there’s a variety of types and sizes available. In this article, we’ll explore container dimensions, from standard to high cube and open-top containers, helping you make informed decisions about the best container type for your needs.

Types of Containers

Beyond the standard 40-foot container, there are other options like refrigerated, open-top, platform, and tank containers.
