Hollow Section Rectangular Pipe Black Carbon Steel Welded Square Steel Pipe/Tube
RHS Steel, also known as rectangular hollow structural sections are commonly used as standard steel frames which can be loaded from different directions in the structural applications of buildings. RHS Steel uses are endless as its smooth flat surfaces can make construction easier. Rectangular hollow sections or rec tubes are cold formed and welded from either hot rolled, cold rolled, pre-galvanized or stainless steel. In order to form the rectangular steel section the appropriate mother tube, a round steel tube, has to be formed first. |
