Tree stands are disclosed for providing an elevated standing location. The tree stand can include a support post, a seat rotatably coupled to the first end of the support post, and a platform rotatably coupled to the second end of the support post. The platform can comprise a plurality interconnected polygonal shapes defining a top standing surface. The platform can be a grating that has load bearing properties and that can be cast from a mold. The platform includes a perimeter wall, a surface portion, and one or more reinforcement walls. A height or thickness of the surface portion is less than a height or thickness of the perimeter wall and/or the reinforcement walls.

1. A load bearing platform for a tree stand configured to attach to a tree or other elongated structure to support a user at an elevated position, the load bearing platform comprising: a perimeter wall comprising a perimeter boundary and area of the load bearing platform, wherein the perimeter wall is a perimeter wall comprising a perimeter boundary defining an area of the load bearing platform, wherein the perimeter wall is formed by structural ribs, wherein each of the structural ribs of the perimeter wall comprises an upper horizontal segment connected to a lower horizontal segment by a vertical segment, wherein each of the structural ribs have a first height extending from a bottom surface of the lower horizontal segment to a top surface of the upper horizontal segment;a surface portion spanning the area defined by the perimeter wall and formed of surface ribs arranged in a repeating pattern of polygons, wherein the surface portion is integrally interconnected within an interior surface of the perimeter wall, wherein the surface ribs that form the surface portion have a second height that is less than the first height, and wherein a bottom-most surface of the surface ribs is in a different plane than the bottom surface of each of the structural ribs of the perimeter wall, the second height extending from the bottom-most surface of the surface ribs to a top surface of the surface ribs, wherein each of the top surfaces are coplanar with each other;at least one reinforcement wall formed by a structural rib, wherein the at least one reinforcement wall extends from a first interior point on the perimeter wall following a path of the surface ribs of the surface portion and terminates at a second interior point on the perimeter wall, wherein each structural rib of each reinforcement wall comprises an upper horizontal segment connected to a lower horizontal segment by a vertical segment, wherein each of the structural ribs of the load bearing platform respectively comprises a transverse cross section that is substantially “Z” shaped and the upper horizontal segments and the lower horizontal segments comprise widths greater than a thickness of the vertical segments;wherein the perimeter wall, the surface portion, and the at least one reinforcement wall are integrally cast as a self-supporting, unitary structure configured to support the user. 2. The load bearing platform of claim 1, wherein the repeating pattern of the surface portion is a honeycomb pattern. 3. The load bearing platform of claim 1, wherein the surface ribs of the surface portion have a cross sectional area defined by an upper horizontal segment of the substantially “Z” shaped cross section of the structural rib of the at least one reinforcement wall. 4. The load bearing platform of claim 1, wherein a lower horizontal segment of the substantially “Z” shaped cross sections has a larger area than an upper horizontal segment of the substantially “Z” shaped cross sections. 5. The load bearing platform of claim 1, wherein an upper horizontal segment of the structural ribs has a trapezoidal cross section. 6. The load bearing platform of claim 5, wherein the structural ribs further comprise a lower horizontal segment having a trapezoidal cross section. 7. The load bearing platform of claim 1, wherein the structural ribs of the perimeter wall and the at least one reinforcement wall have a transverse cross section comprising an offset parting line. 8. The load bearing platform of claim 7, wherein the offset parting line intersects at vertical segments of the structural ribs for the perimeter wall and the at least one reinforcement wall. 9. The load bearing platform of claim 1, wherein a cross section of the structural ribs of the perimeter wall is the same as a cross section of the structural rib of the at least one reinforcement wall. 10. The load bearing platform of claim 1, wherein the perimeter wall defines a height of the load bearing platform. 11. The load bearing platform of claim 1, wherein the structural rib of the at least one reinforcement wall has a third height that is greater than the second height of the surface ribs of the surface portion. 12. The load bearing platform of claim 1, wherein the at least one reinforcement wall is a plurality of reinforcement walls. 13. A tree stand comprising the load bearing platform of claim 1. 14. The load bearing platform of claim 1, wherein the load bearing platform consists essentially of the perimeter wall, the surface portion, and the at least one reinforcement wall. 15. A method of casting the load bearing platform of claim 1, the method comprising the steps of:obtaining a casting mold to cast the load bearing platform, the casting mold having a top mold and a bottom mold that meet with an offset parting line, the casting mold configured to cast the structural ribs of the perimeter wall, the casting mold further configured to cast the surface ribs of the surface portion that span the area defined by the boundary formed by the perimeter wall;stacking the top mold and the bottom mold together to meet at the offset parting line and to form a cavity;injecting a molten material into the cavity;allowing the molten material to cool; andseparating the top and bottom molds of the casting mold and removing the load bearing platform from the casting mold.
