Hollow Sections : Specifications | Types | Circular Hollow Section Dimensions | Square Hollow Section Dimensions | Rectangular Hollow Section Sizes Custom Hollow Sections in Mild Steel, Stainless Steel, and Galvanized Variants – ASTM A500 Certified. Wide Size Range and Profiles Including Square, Rectangular, and Circular Tubes. Available in Seamless and Welded Types with Multiple Size Options. Hollow Sections are manufactured steel profiles with hollow cross-sections, available in various shapes such as square, rectangular, and circular. These sections are produced primarily through cold forming and electric resistance welding (ERW) of steel coils or strips. The process involves shaping the flat steel into the desired form and then welding the seam longitudinally to create a strong, lightweight structural component. Post-welding processes like heat treatment, straightening, and surface finishing ensure dimensional accuracy, uniform wall thickness, and enhanced mechanical properties, making hollow sections ideal for structural and load-bearing applications. One of the key benefits of hollow sections is their high strength-to-weight ratio, which provides excellent structural support while reducing overall material usage and costs. Their closed shape offers superior resistance to torsion, bending, and compression compared to open sections such as angles or channels. Hollow sections also provide aesthetic advantages due to their clean lines and smooth surfaces, making them popular for architectural projects. Additionally, they offer ease of fabrication, welding, and installation, which helps reduce construction time and labor expenses. Hollow sections are available in a broad range of sizes, with outer dimensions ranging typically from 20 mm to over 600 mm, and wall thickness varying from 1.5…
