Rack shelving is a type of storage system that consists of horizontal shelves supported by vertical frames. It is commonly used in warehouses, retail stores, and garages to organize and store various items efficiently. The design allows for easy access to products and maximizes vertical space, making it ideal for both heavy and lightweight items. These shelving units come in various sizes and materials, such as metal or wood, to accommodate different storage needs. Rack shelving can be adjustable, allowing users to change the height of the shelves to fit different items, enhancing versatility and functionality in any space.
