Squared rectangle hollow universal beam with bent corners is formed by the bending of steel plate which can greatly improve the moment of inertia, thereby improving the anti-bending and anti-twisting strength of the universal beam, which can release the capabilities of the material as much as possible. The design of the bent corners thereof can further improve the moment of inertia thereof and improve the strength. The antinode plate structure design of the inner wing plate or inner web thereof can further enhance the structural strength of the hollow universal beam and increase the carrying capacity thereof.
