C 125x50x17x2.25 Tecnometal · Weight & Dimensions

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.

Also known as: Montén de 5 pulgadas (México) · PFC 125x50x17x2.25 (UK / Australia)

The C 125x50x17x2.25 steel profile weighs 4.3 kg/m (2.90 lb/ft), has a depth of 125 mm (4.92 in), flange width 50 mm (1.97 in). Cross-sectional area: 549.444 mm². Moment of inertia Ix = 131.17 cm⁴, Iy = 18.784 cm⁴.
