A metal crate is used as a means of item storage, with a capacity of 80 weight. They can be stacked up to three high, giving 240 capacity, the maximum for a single tile.
A metal crate, like any other container, can be destroyed by a sledgehammer. If it is destroyed, all of its contents will spill onto the floor. Furthermore, any crates stacked on top of that crate will fall down.
