Seamless steel tubes are widely used in cantilever structures due to their high strength, uniformity, and durability. These tubes are manufactured without welded seams, ensuring superior structural integrity and resistance to stress concentrations-critical for cantilever applications where load-bearing capacity and stability are essential.
