A Standard or Step Waterfall Wire Deck rests on the step part of the beam while part of the decking rests on top of the beam. The edge of the deck hangs over the face of the beam for added support. The step carries the weight of the decking and its contents across the surface area of the step beam. This image show a “U” Channel cross support that rests on the step as well. This adds to the strength of the Wire Deck. The more Channels a deck has the more it can hold. A typical wire deck comes with 3 channels and larger ones will have 4. The face of the decking creates a partially unobstructed view of the entire beam face for reading the labels and product barcodes.
