U 250x70x6.3
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 250x70x6.3 steel profile weighs 28.2 kg/m (18.94 lb/ft), has a depth of 250 mm (9.84 in), flange width 70 mm (2.76 in). Cross-sectional area: 2,337.9 mm². Moment of inertia Ix = 1,951.8 cm⁴, Iy = 81.12 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 6.3 mm ≈ 3 gauge (Manufacturers Standard Gage)
