C 75x40x15x3.04 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 3 pulgadas (México) · PFC 75x40x15x3.04 (UK / Australia)

The C 75x40x15x3.04 steel profile weighs 3.9 kg/m (2.65 lb/ft), has a depth of 75 mm (2.95 in), flange width 40 mm (1.57 in). Cross-sectional area: 501.599 mm². Moment of inertia Ix = 42.463 cm⁴, Iy = 10.695 cm⁴.
