U 250x70x2
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 steel profile weighs 8.9 kg/m (6.01 lb/ft), has a depth of 250 mm (9.84 in), flange width 70 mm (2.76 in). Cross-sectional area: 768 mm². Moment of inertia Ix = 672.45 cm⁴, Iy = 30.8 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
