C 300x85x25x3.04 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 12 pulgadas (México) · PFC 300x85x25x3.04 (UK / Australia)

The C 300x85x25x3.04 steel profile weighs 11.9 kg/m (8.02 lb/ft), has a depth of 300 mm (11.81 in), flange width 85 mm (3.35 in). Cross-sectional area: 1,519.999 mm². Moment of inertia Ix = 1,976.56 cm⁴, Iy = 135.588 cm⁴.
