Metal rods are solid, elongated pieces made from various metals, such as steel, aluminum, or copper. They are commonly used in construction, manufacturing, and engineering due to their strength and durability. Metal rods can be found in different sizes and shapes, including round, square, or rectangular profiles. These rods serve multiple purposes, such as providing structural support, acting as connectors, or serving as tools. In mechanical engineering, for example, metal rods are often used in machinery and equipment to transmit force or motion. Their versatility makes them essential components in many industries.
