Heavy Duty Hot Rolled Hollow Sections for Industrial Applications
Specifications
Hot rolled hollow sections are steel profiles formed at high temperatures—typically exceeding 900°C—resulting in a product with superior structural integrity, uniform material properties, and reduced internal stress. Available in circular (CHS), square (SHS), and rectangular (RHS) shapes, these closed sections offer exceptional strength-to-weight ratios, high torsional resistance, and excellent performance in compression, making them ideal for heavy-duty columns, bridges, and large-span industrial or commercial structures.

| A Applies to specified wall thicknesses (t) equal to or greater than 0.120 in. (3.05 mm). For lighter specified wall thicknesses, the minimum elongation values shall be calculated by the formula: percent elongation in 2 in. (50mm) = 56t + 17.5, rounded to the nearest percent. For A500M use the following formula: 2.2t + 17.5, rounded to the nearest percent. B Applies to specified wall thicknesses (t) equal to or greater than 0.180 in. (4.57 mm). For lighter specified wall thicknesses, the minimum elongation values shall be calculated by the formula: percent elongation in 2 in. (50 mm) = 61t + 12, rounded to the nearest percent. For A500M use the following formula: 2.4t + 12, rounded to the nearest percent. C Applies to specified wall thicknesses (t) equal to or greater than 0.120 in. (3.05 mm). For lighter specified wall thicknesses, the minimum elongation values shall be by agreement with the manufacturer. D The minimum elongation values specified apply only to tests performed prior to shipment of the tubing. |
