A shelving apparatus includes a supporting frame, a plurality of foldable posts for coupling with the supporting frame, and a post joint. Each foldable post includes an upper post member and a lower post member, wherein each of the upper and lower post members has a first post wall and a second post wall extended from the first wall at an angle. The post joint includes an engaging tongue extended from an end portion of the first post wall of the upper post member, an engaging groove provided at an end portion of the first post wall of the lower post member, and a pivot hinge pivotally coupled the second post walls of the upper and lower post members. When the post members are pivotally moved to engage the engaging tongue with the engaging groove, the upper and lower post members are coupled with each other end-to-end.

Storage and grow rack systems include splice joints for stacking and joining upright posts, structural support beams with integral drainage, and studs or rivets providing releasable attachment of cross members to upright posts.

A post coupler having a first body portion and a second body portion. Each body portion having an inner edge, an outer edge, a reverse flange, and at least one post alignment tab. Each reverse flange forms a post receiving slot. The first and second body portions are coupled to each other at approximately 90 degrees. A method of using the post coupler comprises the steps of a) providing a first post section and a second post section, b) inserting the first post section along the post receiving slots until the first notch interacts with the tab, and c) inserting the second post section along the post receiving slots until the second notch interacts with the tab.

A detachable and combinable cabinet and its assembly method comprises a combinable cabinet; the combinable cabinet includes a plurality of central unit cabinets, end unit cabinets, and connecting components used to assemble a plurality of central unit cabinets and end unit cabinets together; a plurality of the end unit cabinets are respectively positioned at top and bottom of the central unit cabinets; a modular design for the central unit cabinets and the end unit cabinets allows for the combination of units with relatively few specifications to create cabinets of various heights or widths, significantly simplifying the manufacturing process and greatly reducing storage and packaging volume, which facilitates storage, transportation, and protection, saving on shipping costs. It also provides an excellent solution for the production, packaging, and transportation of extra-long, extra-wide, and oversized cabinets. Additionally, it eliminates the need for extensive welding and grinding processes traditionally required in cabinet manufacturing.

A storage rack is provided. The storage rack includes a plurality of upright supports and a shelf support supported by each of the plurality of upright supports. The plurality of upright supports include a first upright support, a second upright support, a third upright support, and a fourth upright support each having an opening. The shelf support includes a shelf beam extending between the first and second upright supports. The shelf beam includes a body, a first tab, and a second tab. The first and second tabs each extend outwardly from an end of the body and are configured to engage the first upright support at opposing sides of the opening of the first upright support in order to detachably connect the shelf beam to the first upright support.
