A joist, comprising:
- a first leg portion, a second leg portion, and a central portion, wherein each of the first leg portion and the second leg portion define a first side, a second side, and a distal side;
- wherein each of the first sides and the second sides define a first stiffener therein;
- wherein each of the distal sides define two second stiffeners and two third stiffeners therein;
- wherein the two second stiffeners have a depth different than that of the two first stiffeners;
- wherein the two third stiffeners have a depth different than that of the two second stiffeners;
- and
- wherein a longest flat portion of the distal sides of the first leg portion and the second leg portion is located at a relative middle of said distal sides.
