Circular Section Steel Pipes, Circular Hollow Section Mild Steel Pipe, Hot Rolled Circular Hollow Section Suppliers
Bhawal Steel Agency is a pipe manufacturing company that makes Circular section steel pipes in various custom-made shapes, sizes and thicknesses. We are a famous manufacturer for dealing with quality products; call us to know more.
Circular hollow section materials are available with square, rectangular cross-sections for various engineering and building industries. A variety of materials are used to roll circular steel pieces. Hot and cold rolled steel tubes are the most frequent. Hot rolled hollow sections are mainly used for structural purposes, whereas cold steel tubes have superior bending ability and a more attractive look after powder coated. Examples of typical uses are building vehicles, structure offshore, constructing machines, agricultural equipment, etc. Hollow Circular Section Steel pipe, often known as round steel tubes, is a typical steel section used in several shapes across a wide range of industries. Slit coil or steel sheets are used to roll the steel sections. In addition, we offer a variety of circular hollow section steel grades. In a typical cold forming steel factory, the slit strip of steel coil passes through the size and forming section. The mill is made up of several passes through which the sheet is slowly created, with each pass bending the steel sheet more and more and modifying the radii. This is repeated until the two ends of the steel are forced together and welded together. The specification of Circular hollow sections are available in sizes up to 300 mm NB, wall thickness is available from 1.8-14.27 mm, outer diameter 1.8- 457.2 mm.
