C 127x51x19x3.4 Hylsa · Weight & Dimensions

Hylsa, 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 5 pulgadas (México) · PFC 127x51x19x3.4 (UK / Australia)

The C 127x51x19x3.4 steel profile weighs 6.5 kg/m (4.38 lb/ft), has a depth of 127 mm (5.00 in), flange width 51 mm (2.01 in). Cross-sectional area: 831.747 mm². Moment of inertia Ix = 198.977 cm⁴, Iy = 28.584 cm⁴.
