Rectangular Hollow Sections for Structural Support


Specifications


Rectangular Hollow Sections (RHS) are structural steel tubes characterized by a rectangular cross-section and a hollow interior. They offer a high strength-to-weight ratio and directional bending resistance, making them ideal for load-bearing applications like building frames, beams, and columns. RHS typically feature sizes ranging from 20x10mm to 400x200mm with wall thicknesses between 1.5mm and 12.5mm+, providing versatile, cost-effective solutions for construction and mechanical engineering.

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.
