Pipe steel square profile. delivery over 8-10 tons

Steel profile square pipe Description A pipe with a cross section other than round and having four faces equal in size is called a steel profile square pipe. It has a cross section in the form of a square and is used in various areas of construction, as well as in the creation of metal structures. Steel profile square pipe is produced by cold and hot deformation (seamless) or by electric welding of a metal sheet bent in a certain position (seam) in accordance with GOST 13663-86 from alloy and carbon steels St2ps, St2sp, St4sp, St4ps, 10, 20, 35, 08kp. According to the type of processing, square pipes are: processed (heat treatment of the seam and all surfaces), raw, galvanized, non-galvanized. According to the quality of the pipes, profile square pipes are divided into classes: A - normalized according to mechanical characteristics, B - normalized according to chemical characteristics, C - normalized according to mechanical characteristics and chemical composition, D - normalized according to internal hydraulic pressure.
