C 250x85x25x3.05

BR — 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 250x85x25x3.05 steel profile weighs 15.2 kg/m (10.22 lb/ft), has a depth of 250 mm (9.84 in), flange width 85 mm (3.35 in). Cross-sectional area: 1,396.3 mm². Moment of inertia Ix = 1,324.4 cm⁴, Iy = 133.8 cm⁴.
