Abstract- Cold formed steel are nowadays used for building construction especially non-load bearing partition, curved walls, etc due to its flexural strength and good appearance. The cold formed steel enhances the mean yield stess by 15 % to 30 % as compared to hot rolled steel. In this paper detailed parametric and comparative study of cold formed steel sections by different codes is carried out for prediction of flexural strength of beams. Various codes predict different strength. The flexural strength of cold formed steel beam is carried out and presented using CUFSM software which uses Direct Strength Method for prediction of flexural strength and this flexural strength is compared with IS 801-1975 and experimental results
