C 175x65x20x3.5 SAISC · Weight & Dimensions

SAISC, 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 7 pulgadas (México) · PFC 175x65x20x3.5 (UK / Australia)

The C 175x65x20x3.5 steel profile weighs 8.8 kg/m (5.91 lb/ft), has a depth of 175 mm (6.89 in), flange width 65 mm (2.56 in). Cross-sectional area: 1,126.907 mm². Moment of inertia Ix = 515.372 cm⁴, Iy = 60.588 cm⁴.
