Steel bracket column used for factory

The invention discloses a steel bracket column used for a factory. The two sides of a web plate of the steel bracket column are respectively fixedly provided with a row of brace rods (2), the brace rods (2) at the two sides of the web plate are symmetrical to the web plate (1) and are vertical to the plane on which the web plate (1) is located; and prestress construction members (3) are connected between the uppermost brace rod (2) and the bottommost brace rod (2) at each side of the web plate (1). Compared with the prior art, a certain amount of brace rods are fixed on the web plate of the steel bracket column, and prestress is applied to the prestress construction members, thus the effect of reducing out-plane calculated length of the construction member, and finally the out-plane stability of the construction member is guaranteed, thus the construction member is required to meet the in-plane stability only. Besides, the structural design in the invention is reasonable, not only is the structure simple, but
