Hot & Cold Rolled Steel

STEEL SECTIONS• The steel sections most used in structural steelwork are standard hot-

rolled steel universal beams and columns together with a range of tees, channels and angles.

• Universal beams and columns are produced in a range of standard sizes and weights designated by serial sizes. Within each serial size, the inside dimensions between flanges and flange edge and web remain constant, and the overall dimensions and weights vary.

STEEL SECTIONS• This grouping of sections in serial sizes is convenient for production

within a range of rolling sizes and for the selection of a suitable size and weight by the designer.

• The deep web to flange dimensions of beams and the near similar flange to web dimensions of columns are chosen to suit the functions of the structural elements.

• Because of the close similarity of the width of the flange to the web of column sections, they are sometimes known as ‘broad flange sections’.

Hot Rolled Section• The metallurgical process of Hot

rolling, used mainly to produce sheet metal or simple cross sections from billets describes the method of when industrial metal is passed or deformed between a set of work rolls and the temperature of the metal is generally above its recrystallization temperature.

• Hot rolling permits large deformations of the metal to be achieved with a low number of rolling cycles. 

• Hot rolling is primarily concerned with manipulating material shape and geometry rather than mechanical properties.  

• You’ll find hot rolled products like hot rolled steel bars in the welding and construction trades such as making railroad tracks, I-beams, and other steel construction materials that don’t require super precise shapes.

Cold Rolled Section• Cold rolled steel is manufactured at

temperatures below its recrystallization temperature, typically at around room temperature.

• Because the steel is manufactured at a much lower temperature, there’s no need to worry about the steel shrinking or changing form or appearance.

• The cold rolled steel end products like cold finished steel bar has a much smoother appearance and may have square corners more accurate in dimension and finish.

• Cold rolled steel is much more preferred in the machining world where the quality of the steel is an important factor of the quality of the final product, and the appearance of the steel is also an important factor.
