A shelf rack is a shelving system in which a variety of different goods can be stored. Shelf shelves accommodate small boxes as well as large objects and special shapes. They are often used in warehouses, archives, offices, and retail stores to make efficient use of available space and provide orderly storage.
The shelving system consists of horizontal shelves that are mounted on vertical supports or posts. The shelves can be made of wood, metal or plastic and are height-adjustable to meet various storage requirements. Clamps, screws or bolts securely connect the shelves to the frame. A shelf rack can also be equipped with back walls, side walls or dividers to improve stability.
