Cold formed steel is basic component in the construction of lightweight prefabricated structures like stud frame panels, trusses and prefabricated structures. This thesis work deals with the details of an experiment on cold formed steel section subjected to compression and flexure. The main aim of the research work is to find out the effect of the l5 mm,20 mm and 25 mm lip in cold formed angle and cold formed channel section. This analysis carries an angle and channel section of thickness 2 mm and 3 mm with different sizes. Total 32 experiment are carried out and for flexure testing two-point loading is applied to cold formed member. The experimental results show that the effect of the lip in in case of channel section size 100x50x3 lip help to increase compressive strength up to 30% to 50. While in case of square channel section size 100x100x2, lip is not much effective because the unstiffened portion of member buckle easily. In case of angle section size 85x50x3 lip help to increase compressive strength up to 20% to 47%. While in case of angle section size 100x85x2 lip help to increase strength up to 25% to 42%. During flexure testing bending consistently occurred towards the web in the plain channels and towards the lips in the lipped channels. During compression test buckling of member occurs first in unstiffened member and then towards stiffened member. The effect of the lip in square channel section is more effective. lip portion enhance the flexure strength of member up to 262 % but in case of channel section lip help to increase strength about 20% to 50%.
