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 250x100x25x3.75 steel profile weighs 14.0 kg/m (9.40 lb/ft), has a depth of 250 mm (9.84 in), flange width 100 mm (3.94 in). Cross-sectional area: 1,782.483 mm². Moment of inertia Ix = 1,721.885 cm⁴, Iy = 228.08 cm⁴.
