Hollow Section

Circular hollow sections, also known as round steel tubes.These steel sections are rolled from steel sheet or slit coil. The slit strip of steel coil goes through a forming and sizing section in a normal cold forming steel mill. The mill consists of a number of passes through which the sheet is gradually formed, each pass bending the steel sheet more and changing the radii on each pass. This is done until the two ends of the steel is pressed together and then welded inline.

Rectangular Hollow Sections, more often referred to as RHS, is arguably the strongest hollow section with the largest amount of functionality. It is a very popular choice amongst builders and others completing high functioning structural or mechanical projects.
