What is ISO corner?
Description. Standard ISO corner casting made from special steel designed for low temperature working at -40°C as standard. These are the fittings found on all ISO type Containers used for shipping. They are designed to lift or tie down from.

Why do containers have ridges?
The indentations help maintain the container structure during this process. The smooth walled plastic packages you may be familiar with (such as peanut butter) are “cold-filled” and don’t experience the same temperature fluctuations.
Are the walls of a shipping container structural?
Even though most of the container load is carried through the corner castings, the walls still carry some weight and hold the shape of the container – making them very important to the structural integrity.
How thick is the wall of a shipping container?

How high can containers be stacked?
Never stack containers higher than eight tall to maintain structure. Always ensure corner posts are aligned on all stacks. Always use lashing rods to secure each unit and use other methods alongside if possible (including twist locks).
