A pallet racking storage system is made up of 2 basic parts: frames (or uprights), and beams (or cross beams).
Frames are the vertical structures of a pallet rack system, and beams are the horizontal structures and what you place your pallets on. Beams come in 2 basic designs: Box Beams Step Beams Box beams have a basic rectangular shape, similar to the shape of a 2X4 board with clips on the end to attach to a vertical frame. Step beams, on the other hand, have (you guessed it!) a step in their design. Almost like an L-shape, with slots along the lower edge of the step.
To gain a better understanding of the beam designs, we put step beams, and box beams head to head against 3 factors to see who comes out on top.
