Wide Span Racking-SMACO Wide span racking is a bulk storage type rack that is used for materials that are stored by hand rather than on pallets. Components consist of uprights and beams that come in a variety of lengths and heights. Since wide span racking is used for hand storage, some type of decking will be required such as wood, solid metal decks or wire decking. Changing beam levels is extremely easy with the wide span system. The beams for wide span racking can hold up to 3000# depending on the length of the beam. The frames can go to heights of 20ft and can be accessed mechanically by devices that lift the operator to required height.
