Hot Finished Rectangular Hollow Sections - 350x250x14.2

Hot-finished rectangular hollow sections (RHS) are flat-sided, box-shaped steel tubes manufactured at very high temperatures to ensure a uniform metal structure. Shaping the steel while it is red-hot eliminates the internal stresses found in cold-formed alternatives, making these tubes highly reliable under heavy loads and easier to weld or cut. Their rectangular profile provides superior bending strength along their deeper axis, while the flat faces allow for quick and easy connections to other structural parts. These robust tubes are widely used in demanding engineering applications, such as heavy bridge trusses, building columns, and large-scale industrial frameworks.
