ISO Standard
Structure of ISO Shipping Container
* The structure of ISO standard containers differs slightly depending on the manufacturer.
As you can see from the drawing above, the corner posts that look like pillars at the four corners of the container are made by bending steel plates, not pillars. In addition, corner casting is a cast metal and the C channel is mainly used for the part that corresponds to the floor beam in architecture, but a forklift pocket is open in the middle.
The ISO standard container is a panel structure (wall structure) in which a durable corrugated steel plate (corrugated sheet) supports the skeleton.
