2) Decking section
A completely fabricated decking assembly with reinforcing members ready for installation upon supporting storage rack framing. One or more decking sections are used to form a shelf surface.
3) Double deep rack
A racking system that is used where a greater storage density is required. It accommodates two pallet loads stacked back-to-back and requires special fork trucks called reach trucks.
4) Double row, double face shelving
One generally continuous row of units joined together, back to back and side to side to be serviced from two service aisles.
5) Drawer storage
Storage utilizing drawers in cabinets or within shelving systems and are suitable for applications where volume of inventory turnover is low and where smaller items are being stored.
6) Drive in rack
This type of rack utilizes upright frames, rails, and ties to allow a vehicle to enter a storage rack structure from one side only and pick up or deliver pallets on continuous rails. Drive-in rack is used to address repetitive products and serves to take advantage of cubic space available for storage, when such unit loads do not lend themselves to block stacking.
7) Drive through rack
This rack is similar to drive-in rack except that the fork truck is capable of driving straight through the structure at any storage location along the aisle.
8) Flow rack
Storage rack that utilizes shelves (metal) that are equipped with rollers or wheels. Such an arrangement allows product and materials to "flow" from the back of the rack to the front and therein making the product more accessible for small-quantity order-picking.
9) Free span
The distance between supports in a storage rack.
