Ue 100x40x17x2.25 ABNT NBR 6355 · Weight & Dimensions

ABNT NBR 6355 · 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 4 pulgadas (México) · Ue 100x40x17x2.25 (UK / Australia)

The Ue 100x40x17x2.25 steel profile weighs 3.5 kg/m (2.37 lb/ft), has a depth of 100 mm (3.94 in), flange width 40 mm (1.57 in). Cross-sectional area: 448.194 mm². Moment of inertia Ix = 67.03 cm⁴, Iy = 10.164 cm⁴.
