The Grainger Freestanding Metal Shelving Racks are industrial-grade steel shelving units designed for warehouses, distribution centers, retail stores, and other commercial applications. They feature a boltless design for quick assembly and adjustable shelves to accommodate various storage needs. The uprights are made from 14-gauge steel with 5 shelves per section in a variety of depths and widths. Weight capacities range from 1800 lbs to 3600 lbs per shelf depending on the model. These heavy-duty shelves can be configured as single or double-sided units and include protective end panels and cross braces for stability. Multiple sections can be combined to create a larger shelving system.
