d. Crates, general.

(1) Definition of a crate. A crate is a rigid container constructed of a structural member (wood or metal) fastened

together to protect the contents. It may be sheathed or unsheathed (open), demountable (reusable), or nondemountable

(one trip).

(2) Use of crates. Crates are generally selected in preference to boxes for shipment of supplies and equipment

when an item exceeds 10 feet in any direction or the net weight of the contents exceeds 1,000 pounds (454kg).

(3) Classification of crates. Since there are so many different crate specifications, it is difficult to give one

classification for each crate specification. Some crates are designed for general use and others for specific use. Crates

may be designed for domestic or overseas shipment. For practical purposes, a classification may include one or a

combination of several of the above.

(a) Open crates. An open crate is a container formed of framing members (wood or metal) without exterior

sheathing, wood, plywood, fiber board, or paper-overlaid veneer attached to the framing members.

1. Open crates derive their strength from the truss like framework formed by the diagonal vertical, and

longitudinal members.

2. These crates may be covered with a lightweight material for watershed protection but are not to be construed

as sheathed crates.

(b) Sheathed crates. Sheathed crates are similar in construction to open crates except that the frame members

are completely covered with sheathing material, such as plywood, wood, paper-overlaid veneer, or fiber board. Sheathed

crates not only provide mechanical protection to the contents, but also protect the contents from the elements during

outdoor storage.

(4) Crates used for packing IPE for shipment to storage.
