A wooden crate has a self-supporting structure, with or without sheathing. For a wooden container to be a crate, all six of its sides must be put in place to result in the rated strength of the container. Crates are distinct from wooden boxes. The strength of a Wooden Box is rated based on the weight it can carry before the top (top, ends, and sides) is installed, whereas the strength of a crate is rated with the top in place. In general conversation, the term crate is sometimes used to denote a wooden box.
Although the definition of a wooden crate, as compared to a wooden box, is clear, construction of the two often results in a container that is not clearly a crate or a box. Both wooden crates and wooden boxes are constructed to contain unique items, the design of either a crate or box may use principles from both. In this case, the container will typically be defined by how the edges and corners of the container are constructed. If the sheathing (either plywood or lumber) can be removed, and a framed structure will remain standing, the container would likely be termed a crate. If removal of the sheathing results in no way of fastening the lumber around the edges of the container, the container would likely be termed a wooden box.
