There are two types of roll formed beams available:
These beams provide an interior ledge that can be used for supporting accessories such as wire mesh decks and safety bars. The ledge allows the accessories to be mounted flush to the top of the beam. The ledge can also be slotted to provide secure placement of safety bars that snap into place into the beam slots.
Without the interior ledge for support, safety bars and mesh decks must partially hang over the front of the beam face.
Structural beams can only be used in conjunction with structural frames. Structural safety bars or pallet supports can be mounted inside the structural channel.
