RHS has inherently flat surfaces that make it more economical when it comes to joining and fabrication. Also, RHS is functional with clean lines and is used for construction and architectural applications.
RHS is manufactured in a wide range of dimensions and thicknesses, as well as combinations of both. Available thicknesses across the board are 1.6mm-20mm.Dimensions range from 50mm×20mm to 400×30mm.
