Steel tubes, or hollow steel sections, are cylindrical steel products with a hollow interior. These tubes are widely used in construction, structural, and industrial applications due to their high strength, durability, and resistance to bending and torsion. Hollow steel tubes provide excellent load-bearing capacity while being lightweight, making them ideal for structural frameworks, support columns, transportation, and pipelines. Available in various diameters, wall thicknesses, and grades, steel tubes offer design flexibility and cost-effective solutions for a wide range of engineering and architectural projects.
