<p>Cold-Formed Steel (CFS) is popularly used in industrial structures in which the commonly used shapes, such as C section and Z-section. The sigma section exhibits superior bending capacity and possesses a high strength-to-weight ratio. There is a lack of research existing on the sigma section’s impact on the evaluation of flexural strength. Hence, this study aims to examine the flexural strength of a channel section and sigma section subjected to bending. The numerical investigation was conducted by examining different thicknesses and cross-sectional geometries using the software ABAQUS. The numerical findings were subsequently compared with experimental results, demonstrating a high degree of accuracy in their matching. The research conducted a numerical and experimental investigation to determine the parametric studies, such as flange width-to-thickness (B/t) ratio, web depth-to-thickness (W/t) ratio, bending stiffness, ductility index and percentage increase in moment capacity on both the sigma section and channel section. It was observed that transitioning from channel to sigma sections increased strength by 37.21% for plain sections and 35% for lipped sections. Therefore, the sigma section is strongly recommended for its wide-ranging applicability in the construction industry.</p>
