Metal frames are structures made from various types of metals, such as steel or aluminum. They are commonly used in construction, furniture, and art, providing strength and durability. Metal frames can support heavy loads and resist environmental factors like moisture and pests, making them ideal for both indoor and outdoor applications. In the context of furniture, metal frames are often found in items like chairs, tables, and beds. They can be designed in various styles, from modern to industrial, and are frequently combined with materials like wood or glass to create aesthetically pleasing and functional pieces.
