Cold-Formed Rectangular Hollow Sections - 200x150x10.0

Cold-formed rectangular hollow sections (RHS) are flat-sided, box-shaped steel tubes made by bending flat steel sheets into shape at room temperature and welding the seam. This cold-shaping process triggers "work hardening," which increases the steel's yield strength and makes the finished tube highly resistant to bending. Their flat, straight faces make them much easier to join, bolt, or weld to other flat structural parts compared to round pipes. Thanks to this practical shape and high strength-to-weight ratio, they are a favorite choice for construction frames, machinery scaffolding, and architectural steelwork.
