The containers we use are perfectly standardized, the most common being 10, 20 and 40 feet.
Each container is different, but similar in its resistant characteristics that make them suitable for transport.
The floor of the containers is in solidarity with the outer frame and the steel pillars. They are originally watertight and waterproof. They can be joined together by rigid or mechanical joints, and are stackable up to 5-6 heights depending on the load and use.
