Tubular steel can vary in diameter, thickness, and length depending on the intended application. It is widely used in construction, manufacturing, and various other industries due to its strength, versatility, and relatively low cost. It can be used to create structural components such as columns, beams, and trusses in buildings and bridges, as well as in the production of machinery, furniture, and transporation vehicles. The hollow nature of tubular steel provides several advantages, including reduced weight compared to solid steel components, which can be beneficial for applications where weight is a concern.
