The present disclosure provides a movable load bearing structure having a light weight core covered with at least one polymeric sheet for improving its loading bearing strength. The movable load bearing structure includes indentations, grooves, valleys, channels or other similar depressions on its underside. These depressions are mated with corresponding features for improved loading bearing capabilities. The load bearing structures also includes roughened side edges for improving the strength of the edges. The movable structure may be in the form of a dunnage platform or a container for storing and/or shipping cargo.

The present invention provides a thinner, movable load bearing structure having indentations, grooves, valleys, channels or other similar depressions on its underside. These depressions are mated with corresponding features for improved loading bearing capabilities. The load bearing structures also includes roughened side edges for improving the strength of the edges. The load bearing structure may be a dunnage platform or a container for storing and/or shipping cargo.

The reusable packaging box includes a bottom unit that has a receiving space in which a product may be received, a lower body and an upper body that are provided to each have a box shape with open top and bottom to be coupled to a top of the bottom unit, and a lid that has a receiving space in which the product may be received and is coupled to the top of the upper body. Each of the bottom unit, the upper body and the lower body, and the lid is formed of a material that may absorb an impact and thus may perform both a function of absorbing an impact and a function of packaging an outside of the product.

A pallet includes columns, an upper deck, and a lower deck. The upper deck links upper ends of the columns such that upper surfaces of the columns and upper deck form an upper deck surface. The lower deck links lower ends of the columns such that lower surfaces of the columns and lower deck form a lower deck surface. Fork insertion structures receive forks of a lift apparatus inserted thereto from four sides of the pallet. Outer circumferential projections are formed along a peripheral edge of the upper deck surface, including an extended portion extending outward from the peripheral edge, and a support portion protruding upward from the extended portion. The support portion has a first height in an insertion-corresponding region, and a second height in a general region, the first height being equal to a thickness of the lower deck, the second height being greater than the first height.

A Modular Pallet System for storage and transport of goods, assembled using Stringer Assemblies comprising 2 or more elongate members that translate in relation to each other to facilitate location and clamping of wood, composite or metal Deck Boards. Stringer Assemblies are assembled from 2 or more elongate members that translate in relation to each other to facilitate location and clamping of Deck Boards. Deck Boards can be manufactured from wood, composite or metal. Clamping action can be achieved by screw, wedge, cam or other mechanical means.
