U 250x70x2.25
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 250x70x2.25 steel profile weighs 10.1 kg/m (6.77 lb/ft), has a depth of 250 mm (9.84 in), flange width 70 mm (2.76 in). Cross-sectional area: 862.3 mm². Moment of inertia Ix = 752.97 cm⁴, Iy = 34.3 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2.25 mm ≈ 13 gauge (Manufacturers Standard Gage)
