Square & Rectangular Hollow Sections varies in thickness from 1.6 mm to 16 mm. Generally, the smaller the dimensions, the thinner the metal wall can be. Rectangular Hollow Sections (RHS) or rec tubes are cold formed and welded from either hot rolled, cold rolled, pre-galvanized or stainless steel.
Rectangular hollow sections (RHS) feature longer width-to-height ratios, offering structural flexibility for beams, columns, and general framing. They are commonly used in commercial and industrial construction requiring both strength and flat surface alignment.
