Wooden box
Encyclopedia
A wooden box is a container made of wood
Wood
Wood is a hard, fibrous tissue found in many trees. It has been used for hundreds of thousands of years for both fuel and as a construction material. It is an organic material, a natural composite of cellulose fibers embedded in a matrix of lignin which resists compression...

Boxes as shipping containers

Wooden box
Box
Box describes a variety of containers and receptacles for permanent use as storage, or for temporary use often for transporting contents. The word derives from the Greek πύξος , "box, boxwood"....

es are often used for heavy duty packaging when
  • high strength is needed for heavy and difficult loads
  • long term warehousing may be needed.
  • large size is required
  • rigidity and stacking strength is critical


Boxes and crate
Crate
A crate is a large shipping container, often made of wood, typically used to transport large, heavy or awkward items. A 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...

s are not the same. If the sheathing of the container (plywood, lumber, etc.) can be removed, and a framed structure will remain standing, the container would likely be termed a crate. If removal of the sheathing resulted in there being no way of fastening the lumber around the edges of the container, the container would likely be termed a wooden box.

The strength of a wooden box is rated based on the weight it can carry before the cap (top, ends, and sides) is installed. "Skids" or thick bottom runners, are sometimes specified to allow forklift trucks access for lifting.

Performance is strongly influenced by the specific design, type of wood, type of fasteners (nails, etc.), workmanship, etc.

Nailed wood box

A nailed wooden box is constructed of pieces of lumber (sometimes with reinforcing battens, cleats, etc.) attached by nails or other suitable fasteners. It usually completely encloses the contents. A box usually has a bottom and four side panels and often has an attachable top.

Cleated box

A cleated box has five or six panel faces with wood strips attached to them. The panels can be made of plywood

, solid or corrugated fiberboard, etc. Wooden cleats reinforce the panels.

Wirebound box

Very thin lumber is used for a wirebound box. Wires are stapled or stitched to the girth and to wood cleats. These are sometimes used for produce
Produce
Produce is a generalized term for a group of farm-produced goods and, not limited to fruits and vegetables . More specifically, the term "produce" often implies that the products are fresh and generally in the same state as where they were harvested. In supermarkets the term is also used to refer...

 and for heavy loose items for military or export use. These are lighter than wood boxes or crates. They have excellent tensile strength to contain items but not much stacking strength.

Skid box

A skid box is a wood, corrugated fiberboard, or metal box attached to a heavy duty pallet
Pallet
A pallet , sometimes called a skid, is a flat transport structure that supports goods in a stable fashion while being lifted by a forklift, pallet jack, front loader or other jacking device. A pallet is the structural foundation of a unit load which allows handling and storage efficiencies...
