Racks are structures designed to hold or support items, often used for storage or organization. They can be made from various materials, such as metal, wood, or plastic, and come in different shapes and sizes. Common types of racks include shelves, clothes racks, and bike racks, each serving specific purposes in homes, businesses, or public spaces. In addition to their practical uses, racks can enhance the aesthetic appeal of a space. For example, display racks in retail stores showcase products attractively, while wine racks in homes can serve as both storage and decoration. Overall, racks are versatile tools for managing space efficiently.
