Shelving systems are structures designed to hold and organize items, typically consisting of horizontal surfaces supported by vertical frames. They can be made from various materials, such as wood, metal, or plastic, and are used in homes, offices, and warehouses to maximize space and improve accessibility. These systems come in various styles, including bookshelves, storage racks, and display shelves, each serving different purposes. Shelving can be adjustable or fixed, allowing users to customize the height and arrangement of the shelves based on their needs. Proper shelving helps maintain order and efficiency in any environment.
