Product Information
Square Steel Tube, Square Steel Pipe
Square hollow sections are often used for columns, however similarly to RHS sections, they are not often used as beams due to its shape that makes it difficult to bolt to other beams and vice versa. SHSs are often called “box sections”. An example is 100 x 100 x 10 SHS, which is 100 mm deep, 100 mm wide and the wall is 10 mm thick. Similarly to RHS sections, hot rolled SHSs are made at the mill as one piece, whereas cold formed SHSs are made of a flat sheet rolled at right angles and welded. It is therefore easy to note the difference, as the cold rolled SHSs have a weld all along its length.
