C 40x40x10x2 Tecnometal · Weight & Dimensions

Tecnometal, cold-formed sections (Italy) · 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 1 ½ pulgadas (México) · PFC 40x40x10x2 (UK / Australia)

The C 40x40x10x2 steel profile weighs 2.0 kg/m (1.34 lb/ft), has a depth of 40 mm (1.57 in), flange width 40 mm (1.57 in). Cross-sectional area: 253.684 mm². Moment of inertia Ix = 6.796 cm⁴, Iy = 5.256 cm⁴.
