U 90x30x2
BR — Cold-formed Channel
Cold-formed channels (U shapes) are similar to C shapes but without stiffening lips. Used for light structural framing, supports, and secondary members.
The U 90x30x2 steel profile weighs 3.3 kg/m (2.22 lb/ft), has a depth of 90 mm (3.54 in), flange width 30 mm (1.18 in). Cross-sectional area: 288 mm². Moment of inertia Ix = 33.04 cm⁴, Iy = 2.08 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
