Metal beams are structural elements made from various types of metals, commonly used in construction and engineering. They provide support and stability to buildings, bridges, and other structures. The most common types of metal beams include steel beams and aluminum beams, which are chosen for their strength and durability. These beams come in different shapes, such as I-beams, H-beams, and T-beams, each designed for specific load-bearing requirements. Metal beams are often used in frameworks, allowing for larger open spaces without the need for many supporting walls. Their resistance to bending and deformation makes them ideal for heavy loads.
