Appearance As 'Container Wall' in a Shipping Container
A Container Panel, is a piece of metal from a shipping container. Before cut down, the panel is called a container wall. Panels can be obtained by hitting a wall of a container repeatedly with a cutting tool, like an Axe.

Once cut loose, right click the panel and drag it away from the container. Then the panel can be used in a building on top of a floor or foundation as the wall of a building.
