Question

Advantages of cold formed steel sections

Answer 1

Cold forming has the effect of increasing the yield strength of steel, the increase being the consequence of cold working well into the strain-hardening range. ... The effect of cold working is thus to enhance the mean yield stress by 15% - 30%.

Answer 2

Advantages are:                                                                                                     # Cross sectional shapes are formed to close tolerance and these can be consistently repeated for as long as required.                                                          # They are usually light making and easy to transport and erect.                        # All conventional jointing methods can be employed, i.e.,Bolting ,Welding etc.
