Application of cold formed hollow steel sections

hollow sections lies in their smooth surface. Hot formed sections can be pitted, as shown in Figure 1. The main objective of the paper is to compare performance of hot finished and cold formed hollow sections, and to provide guidelines for the selection of rectangular hollow sections in the design of steel structures. 2. Welding in cold formed zones Celsius® Tata Steel in EuropeAll Celsius ® hollow sections are true hot finished, so free from internal stresses and with tight corner radii to maximise weldable-surface and enhance aesthetic appeal, whilst avoiding the risk of brittle fracture which occurs in some cold formed products.

It has its source in a mill process involving rolling the steel at high temperature. It starts from a piece of still billet which is heated up 1700 degrees Fahrenheit (926° Celsius) and then the steel is rolled through the mill into the particular shape.

SQUARE HOLLOW SECTIONS - Steel Tube Manufacturer

Square Steel Tubes Square hollow sections or square tubes are cold formed and welded from either hot rolled, cold rolled, pre-galvanized or stainless steel. In order to form the square steel section the appropriate mother tube, a round steel tube, has to be formed first.

Cold-formed sections are then finished in their 'cold' or normal state into the desired shape. Hot-finished sections are heated and formed into a circular, square or rectangular shape whilst in the normalising temperature range. Hot-finished and cold-formed
