Angular rub rails for trailers

1. A side rail assembly for a flatbed trailer, the side rail assembly comprising:

a side rail including a first top horizontal face, a first side vertical face, and a first bottom horizontal face; and

a rub rail coupled to the side rail, the rub rail including a second top horizontal face, a second side vertical face, and a second bottom horizontal face,

wherein the second top horizontal face is coupled to the second side vertical face by a top chamfer,

wherein the top chamfer is diagonally connected to the second top horizontal face and the second side vertical face,

wherein the second bottom horizontal face is coupled to the second side vertical face by a bottom chamfer,

wherein the bottom chamfer is diagonally connected to the second side vertical face and the second bottom horizontal face, and

wherein the side rail assembly, including the side rail and the rub rail, is extruded together as one piece.

2. The side rail assembly of claim 1 , wherein the side rail assembly is formed with extruded aluminum.

3. The side rail assembly of claim 1 , wherein the second top horizontal face steps down into a downward step of the first top horizontal face to provide a surface to attach floor boards to the side rail.

4. The side rail assembly of claim 1 , wherein the first top horizontal face of the side rail includes a hook for attaching cargo securement devices.

5. The side rail assembly of claim 1 , wherein the first bottom horizontal face of the side rail includes

at least one hook for use by sliding winches and notches to mark a location of fasteners joining cross members to the side rail.

6. A side rail assembly for a flatbed trailer extruded as a single piece, the side rail assembly comprising:

a rub portion including

a top horizontal face,

a top chamfer diagonally coupled to the top horizontal face,

an outer vertical face coupled to the top chamfer,

a bottom chamfer diagonally coupled to the outer vertical face,

a bottom horizontal face coupled to the bottom chamfer, and

an inner vertical face coupled to the top horizontal face and the bottom horizontal face; and

a side portion including

a top downward step surface coupled to the inner vertical face, the top downward step surface formed as a step down from the top horizontal face of the rub portion, and

a bottom surface coupled to the inner vertical face, the bottom surface extending outward from the bottom horizontal face of the rub portion.

7. The side rail assembly of claim 6 , wherein the side rail assembly is formed as the single piece with extruded aluminum.

8. The side rail assembly of claim 6 , wherein the top downward step surface of the side portion provides a surface to attach floor boards to the side portion.

9. The side rail assembly of claim 6 , wherein the top downward step surface of the side portion includes a hook for attaching cargo securement devices.

10. The side rail assembly of claim 6 , wherein the bottom surface of the side portion includes

at least one hook for use by sliding winches and notches to mark a location of fasteners joining cross members to the side portion.

11. A side rail assembly, comprising:

a top horizontal face;

a top chamfer diagonally coupled to the top horizontal face;

an outer vertical face coupled to the top chamfer;

a bottom chamfer diagonally coupled to the outer vertical face;

a bottom horizontal face coupled to the bottom chamfer;

an inner vertical face coupled to the top horizontal face and the bottom horizontal face;

a top downward step face coupled to the inner vertical face, the top downward step face formed as a step down from the top horizontal face

wherein the top downward step face provides a surface to attach floor boards to the side rail assembly; and

a bottom extension face coupled to the inner vertical face, the bottom extension face extending outward from the bottom horizontal face,

wherein the side rail assembly is extruded as one piece.

12. The side rail assembly of claim 11 , wherein the top downward step face provides a surface to attach floor boards to the side rail assembly.

13. The side rail assembly of claim 11 , wherein the top downward step face includes a hook for attaching cargo securement devices.

14. The side rail assembly of claim 11 , wherein the bottom extension face includes

at least one hook for use by sliding winches and notches to mark a location of fasteners joining cross members to the side rail assembly.
