Frame material refers to the substance used to construct the frame of an object, such as a building, piece of furniture, or eyewear. Common materials include wood, metal, plastic, and composite materials. Each type has its own properties, affecting durability, weight, and aesthetic appeal. Choosing the right frame material is essential for functionality and design. For example, wood offers warmth and natural beauty, while metal provides strength and modernity. Plastic is lightweight and often more affordable, making it a popular choice for items like eyeglasses. Understanding these materials helps in making informed decisions for various applications.
