U 190x50x4.25
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 190x50x4.25 steel profile weighs 14.3 kg/m (9.64 lb/ft), has a depth of 190 mm (7.48 in), flange width 50 mm (1.97 in). Cross-sectional area: 1,178.3 mm². Moment of inertia Ix = 562.48 cm⁴, Iy = 20.53 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 4.25 mm ≈ 8 gauge (Manufacturers Standard Gage)
