RHS – Rectangular Hollow Sections

Rectangular Hollow Sections (RHS) are not as common as UC’s and UB’s. This is down to the fact that it is much more difficult to bolts an RHS to other beams or to bolt other members to it. RHS’s are described by their depth, width and wall thickness. An example is a 200 x 100 x 8 RHS, which is 200 mm deep, 100 mm wide and the wall is 8 mm thick. Hot rolled RHS’s are made at the mill as one piece, whereas cold formed RHS’s are made of a flat sheet rolled at right angles and welded. It is therefore easy to note the difference, as the cold rolled RHSs have a weld all along its length.

Dimentional Ranges: Size ranges for rectangular hollow sections: from 50×30 to 400×200 mm
