C 220x55x20x1.5 Dabarca · Weight & Dimensions

Dabarca, cold-formed sections · 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.

Also known as: Montén de 9 pulgadas (México) · PFC 220x55x20x1.5 (UK / Australia)

The C 220x55x20x1.5 steel profile weighs 4.2 kg/m (2.85 lb/ft), has a depth of 220 mm (8.66 in), flange width 55 mm (2.17 in). Cross-sectional area: 540.197 mm². Moment of inertia Ix = 372.487 cm⁴, Iy = 21.337 cm⁴.
