The H-shaped steel has the advantages of economic and reasonable section shape, good mechanical property, more uniform extension of each point on the section during rolling, small internal stress, large section modulus, light weight and metal saving compared with the common I-shaped steel, and can lighten the building structure by 30 to 40 percent; because the inner sides and the outer sides of the legs are parallel, and the leg ends are right angles, the welding and riveting workload can be saved by 25 percent by assembling and combining the components, so the components are commonly used for large buildings (such as factory buildings, high-rise buildings and the like) which require large bearing capacity and good section stability, bridges, ships, hoisting and transporting machinery, equipment foundations, supports, foundation piles and the like.

The inner side and the outer side of the flange of the H-shaped steel are parallel or nearly parallel, and the end part of the flange is in a right angle, so that the parallel flange I-shaped steel is obtained. The thickness of the web plate of the H-shaped steel is smaller than that of the common I-shaped steel with the same height of the web plate, and the width of the flange of the H-shaped steel is larger than that of the common I-shaped steel with the same height of the web plate, so that the H-shaped steel is named as wide-flange I-shaped steel. The section modulus, the inertia moment and the corresponding strength of the H-shaped steel are obviously superior to those of common I-shaped steel with the same single weight due to the shape. When the steel is used in metal structures with different requirements, the steel shows excellent performance no matter bearing bending moment, pressure load and eccentric load, and can greatly improve the bearing capacity and save metal by 10-40 percent compared with common I-steel. The H-shaped steel has wide flange, thin web, multiple specifications and flexible use, and can save metal by 15-20% when being used in various truss structures.
