Tecnometal, cold-formed sections (Brazil) · Cold-formed Lipped Channel
Cold-formed lipped channels (C shapes) are lightweight profiles commonly used as purlins, girts, and light framing members. The stiffening lips increase local buckling resistance. Designed per AISI S100 and NBR 14762.
The C 125x50x17x3.04 steel profile weighs 5.7 kg/m (3.83 lb/ft), has a depth of 125 mm (4.92 in), flange width 50 mm (1.97 in). Cross-sectional area: 726.559 mm². Moment of inertia Ix = 169.931 cm⁴, Iy = 23.704 cm⁴.
