H-beams, also known as H-columns, are structural steel beams shaped like the letter "H." They are widely used in construction due to their high strength-to-weight ratio, making them ideal for supporting heavy loads in buildings, bridges, and other structures. The design allows for efficient distribution of weight, providing stability and durability. These beams are manufactured in various sizes and lengths, allowing engineers to select the appropriate dimensions for specific projects. H-beams are often used in combination with other structural elements, such as I-beams and steel plates, to create robust frameworks that can withstand various forces and environmental conditions.
