Hot Finished Square Hollow Section

Hot finished Structural Hollow Sectionswith square, circular or rectangular cross section for a great variety of applications in mechanical engineering and in building industry. Circular steel sections can be rolled from a variety of materials. Most common among them is hot and cold rolled steel tubes. Hot rolled hollow sections are mainly used for structural purposes while tubes rolled from cold steel has better bending ability and gives a better aesthetic appearance after being powder coated. Typical applications include:

Offshore Structures

Agricultural Equipment

Machine Construction

Axles

Structural Steel Projects (airports, stadiums, bridges, etc.)

Cranes

Vehicle Construction

Structural Engineering

Circular hollow sections are also known as round steel tubes, which is one of the common type of steel section that is used in a variety of formats over various industries. The steel sections are rolled from slit coil or steel sheet. We also supply various circular hollow section steel grades. The slit strip of steel coil goes through a sizing and forming section in a normal cold forming steel mill. The mill consists of a number of passes through which the sheet is slowly formed, each pass bending the steel sheet more and more and changing the radii on each pass. This is done until the two ends of steel is together pressed and then welded inline.
