Shelving system

A shelving unit (200) comprising:

• a) a plurality of corner posts (210);
• and
• b) a plurality of shelf assemblies, wherein each shelf assembly is configured to be adjustably coupled to the corner posts (210), each shelf assembly comprising:
• i) a first support beam (221) and a second support beam (222), wherein the first support beam (221) is configured to extend between a first pair of corner posts (210) and the second support beam (222) is configured to extend between a second pair of corner posts (210);
• wherein each of the first support beam (221) and the second support beam (222) comprises:
• 1) a first vertical component (111) and a second vertical component (112) in a single vertical plane,
• 2) a first horizontal component (121) having an end, the first horizontal component (121) extending from a bottom portion of the first vertical component (111) and a second horizontal component (122) having an end, the second horizontal component (122) extending from a bottom portion of the second vertical component (112), wherein the first horizontal component (121) and the end of the second horizontal component (122) are parallel to each other;
• and
• 3) a diagonal component (130) extending from a portion of the first horizontal component (121) and connecting to a top portion of the second vertical component (112), wherein the diagonal component (130) and the first vertical component (111) are disposed on opposing ends of the first horizontal component (121);
• ii) a first side support beam (231) and a second side support beam (232), wherein each side support beam is configured to extend between the first and second pair of corner posts (210);
• and
• iii) a plurality of shelves;
• wherein each shelf is configured to extend between the first support beam (221) and the second support beam (222).

A Z-esque shaped support beam (100) for supporting a shelf assembly, the support beam (100) comprising:

• a) a first beam component (111) having a first edge, a second edge, an end, and a first rivet and a second rivet attached to a same surface of the first beam component (111), wherein the first rivet and the second rivet are disposed on opposing ends of the support beam (100);
• b) a second beam component (112) having a first edge, a second edge and a third rivet and a fourth rivet attached to a same surface of the second beam component (112), wherein the third rivet and the fourth rivet are disposed on opposing ends of the support beam (100), wherein the first beam component (111) and the second beam component (112) are coplanar in a first plane;
• c) a shelf support component (121) extending from the first beam component (111) such that the first beam component (111) and the shelf support component (121) are perpendicular to each other, wherein a first edge of the shelf support component (121) is connected to the second edge of the first beam component (111);
• d) a third beam component (122) having an end, extending from the second beam component (112) such that the third beam component (122) and the second beam component (112) are perpendicular to each other, and such that the end of the third beam component (122) and the shelf support component (121) are parallel to each other, wherein a first edge of the third beam component (122) is connected to the second edge of the second beam component (112);
• and
• e) a diagonal beam component (130) connecting the shelf support component (121) to the second beam component (112), wherein a first edge of the diagonal beam component (130) is connected to a second edge of the shelf support component (121) and a second edge of the diagonal beam component (130) is connected to the first edge of the second beam component (112),
• wherein the first and second rivets are attached to the surface of the first beam component (111) and the third and fourth rivets attached to the surface of the second beam component (112) such that all the rivets project in the same direction that is opposite of a direction of extension of the shelf support component (121) and the third beam component (122).
