DescriptionProcessEquipment Inquiry

Rectangular hollow sections are not as common as UCs and UBs. This is down to the fact that it is much more difficult to bolts it to other beams or to bolt other members to it. RHSs 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 RHSs are made at the mill as one piece, whereas cold formed RHSs 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.
