The system can be used together with pallets that can support a product/merchandise or goods, which are supported, stowed and/or palletized, and subsequently fastened/fixed by a rope, tape and/or strap. In particular, the top frame of the present system is configured to mechanically interact with the strap and efficiently distribute the generated stresses derived from the force tension to which it is subjected to ensure the integrity and bracing of the product. The present system includes a set of structural components, manufactured in a modular manner, which can be assembled and disassembled/taken to pieces, which offers a practical product, easy to handle and transport, and specifically, being manufactured in a modular manner, such that the present structural system can be advantageously transported, packaged using less space, thus improving its logistics and handling. ## Claims ### Claim 1 A top frame structural system comprising: primary and secondary final stringers, each of the primary and secondary final stringers comprising: a corner portion; and a separation system; wherein a corner portion of a primary final stringer is configured to receive a corner portion of at least one of the secondary final stringers, in such a way that a splice of a corner area of the primary final stringer covers the entire corner area of the secondary final stringer; and wherein the separation system in turn comprises upper and lower fasteners and corresponding holes for each of the fasteners, and once the primary and secondary final stringers are joined, the fasteners are configured to ensure a correct hyperstatic coupling between the primary and secondary final stringers. ### Claim 2 (depends on 1) The top frame structural system according to claim 1, wherein the primary and secondary final stringers are each made from a union of an upper portion and a lower portion, joined by a permanent coupling treatment. ### Claim 3 (depends on 2) The top frame structural system according to claim 2, wherein the upper portion and the lower portion each comprise at least one and up to “n” number of flanges, in the respective end portions, which are configured to engage or couple with each other, in a crimping manner, when the upper and lower portion cooperate to form the primary and secondary end stringers. ### Claim 4 (depends on 3) The top frame structural system according to claim 3, wherein the flanges are at least two and up to “n” number of flanges separated at a distance ranging from 1 mm to 25 mm or can be a single flange that extends from one lateral end to the other lateral end of the respective upper and lower stringer. ### Claim 5 (depends on 2) The top frame structure system according to claim 2, wherein the permanent coupling treatment is a process of ultrasonic welding, linear and orbital type vibration welding, hot plate welding and/or combinations thereof, permanently joining the respective upper and lower portions to form a respective final stringer. ### Claim 6 (depends on 2) The top frame structural system according to claim 2, wherein the upper portions, the lower portions or the primary and secondary final stringers, are configured for manufacturing by any selected from the group comprising injection and/or extrusion, blowing, vacuum, spin casting, polymer casting, three-dimensional printing, gas-assisted injection, or a combination thereof. ### Claim 7 (depends on 1) The top frame structural system according to claim 1, wherein the separation system comprises at least two and up to “n” number of holes distributed uniformly and/or in an arrangement in the corner area of each of the final stringers. ### Claim 8 (depends on 7) The top frame structural system according to claim 7, wherein the holes of the separation system are holes with a diameter ranging from ⅛ inch and up to 1 inch having a machining or machined-like finish such as a countersink, chamfer, flare and/or combinations thereof. ### Claim 9 (depends on 1) The top frame structural system according to claim 1, wherein the upper and lower fasteners are any selected from the group comprising: ratchet-type rivets, hot rivets, screws, pins, or combinations of the same. ### Claim 10 (depends on 9) The top frame structural system according to claim 9, wherein the upper and lower fasteners are placed within the holes, wherein the upper fasteners are in an opposite orientation with respect to the lower fasteners. ### Claim 11 (depends on 9) The top frame structural system according to claim 9, wherein the upper and lower fasteners are configured to be removed and/or eliminated by destroying the integrity of the upper and lower fasteners but without damaging the corner areas of the primary and secondary final stingers. ### Claim 12 (depends on 1) The top frame structural system according to claim 1, wherein each of the primary and secondary final stringers has a straight area and a corner area, forming an “L” shape, and wherein the corner area protrudes or projects with respect to the level of the straight area. ### Claim 13 (depends on 1) The top frame structural system according to claim 1, wherein the upper and lower portions have lengths ranging from 5 inches to 70 inches, with widths ranging from 3 inches to 15 inches and thicknesses and/or height ranging from ½ inch to 5 inches. ### Claim 14 (depends on 1) The top frame structural system according to claim 1, wherein the primary and secondary final stringers have lengths ranging from 5 inches to 70 inches, with widths ranging from 3 inches and up to 15 inches and a height ranging from 1 inch to 10 inches. ### Claim 15 (depends on 1) The top frame structural system according to claim 1, wherein the upper portions, the lower portions or the primary and secondary final stringers directly manufactured are manufactured of a material selected from the group comprising: polyethylene (PER or PETE), high-density polyethylene (HDPE), low-density polyethylene (LDPE), polypropylene (PP), polystyrene (PS), ASA, ABS, as well as reinforced plastic materials thermoplastics, or combinations thereof. ### Claim 16 (depends on 1) The top frame structural system according to claim 1, wherein the separation system can be removed/detached from each corner area of each primary and secondary final stringer and the top frame structural system can be switched to a state of disassembled, allowing replacement of primary or secondary final stringers that have suffered structural damage and/or to be able to be transported efficiently. ### Claim 17 (depends on 1) The top frame structural system according to claim 1, wherein the primary or secondary final stringers also comprise at least one and up to “n” number of anti-skid element receiving holes, which are configured to receive inside, hold and/or fix an anti-skid element each. ### Claim 18 (depends on 1) The top frame structural system according to claim 1, wherein at least one of the primary or secondary final stringers further comprise, in their lower or inner portions, an arrangement of ribs. ### Claim 19 (depends on 18) The top frame structural system according to claim 18, wherein the arrangement of ribs is divided into two zones, one corresponding to the corner and the other corresponding to the straight zone. ### Claim 20 (depends on 1) The top frame structural system according to claim 1, wherein at least one of the primary or secondary final stringers do not comprise any arrangement of ribs inside, being substantially hollow or smooth. ### Claim 21 (depends on 1) The top frame structural system according to claim 1, wherein the primary and secondary final stringers further comprise, in their lower or inner portions, a section and/or reinforcement interface having an area with a more concentrated geometry and/or
