Wooden Crates - Durable Self-supporting Structure, Compliant With Ispm 15 Standards For Secure Shipping And Transportation

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.

Skids" or thick bottom runners are sometimes specified to allow forklift trucks access for lifting.

Transportation methods and storage conditions must always be considered when designing a crate. Every step of the transportation chain will result in different stresses from shock and vibration. Differences in pressure, temperature and humidity may not only adversely affect the content of the crate, but also will have an effect on the holding strength of the fasteners (mostly the nails and staples) in the crate. In some countries, any wooden crate being designed to ship overseas must be treated to ISPM 15standards or commonly known as the bug stamp ^[2]to prevent the spread of disease and insects.^[3]

Although the above definition almost always stands true, there are many slightly altered or 'sub-definitions' used by and in various organizations, agencies and documents. This is the result of the small size of the industry and the fact that a single, finite definition of an item that is different every time it is made can be difficult to define.
