A rectangular tube of steel with an even, consistent finish with a smooth, rounded edge. Most Mild Rectangular Hollow Sections will be cold-formed Electro-Resistance Welded (ERW), producing enhanced strength in the finished rectangular tube. This welding process will result in a weld seam. The external weld seam will be scarfed off, resulting in a smooth finish on the external face, but the internal weld seam will remain protruding on the internal face of the tube. Several grades of Mild steel RHS may be available, and care should be taken if a particular grade is required for your application.

Structurally, Steel Rectangle Hollow Sections (RHS) are a material of choice for columns and posts. This is due to the higher strengths of the steel rectangular hollow sections, resulting in lower weights for the same carrying capacity compared to other profiles, and the square flat faces make it easy for construction and fixing to other items with our packing. You will not have to look far to see Rectangular Hollow Sections (RHS) being used. Rectangular Hollow Sections (RHS) are popular due to the smooth, even finish on the outside faces; most Rectangular Hollow Sections will have no sharp edges and require little cleanup after fabrication.
