ABNT NBR 6355 · 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 Ue 125x50x17x3.75 steel profile weighs 6.9 kg/m (4.64 lb/ft), has a depth of 125 mm (4.92 in), flange width 50 mm (1.97 in). Cross-sectional area: 878.733 mm². Moment of inertia Ix = 201.648 cm⁴, Iy = 27.445 cm⁴.
