Steel beams are long, sturdy pieces of steel used in construction to support structures like buildings and bridges. They are designed to bear heavy loads and provide stability, making them essential for creating strong frameworks. Steel beams come in various shapes, such as I-beams and H-beams, each suited for different applications. These beams are made from high-strength steel, which allows them to withstand significant stress and strain. Their durability and resistance to bending make them a popular choice in the construction industry. Engineers often calculate the size and type of steel beam needed based on the specific requirements of a project, ensuring safety and reliability.
