A metal beam is a structural element made from various metals, commonly used in construction and engineering. These beams provide support and stability to buildings, bridges, and other structures by bearing loads and distributing weight. They come in different shapes, such as I-beams and H-beams, which enhance their strength and efficiency. Metal beams are often made from materials like steel or aluminum, known for their durability and resistance to bending. They are essential in creating frameworks for large structures, ensuring safety and longevity. Proper design and installation of metal beams are crucial for the overall integrity of a construction project.
