U 250x100x6.3
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.
Also known as: U 250x100x6.3 (UK / Australia)
The U 250x100x6.3 steel profile weighs 21.1 kg/m (14.17 lb/ft), has a depth of 250 mm (9.84 in), flange width 100 mm (3.94 in). Cross-sectional area: 2,715.9 mm². Moment of inertia Ix = 2,513.15 cm⁴, Iy = 233.38 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 6.3 mm ≈ 3 gauge (Manufacturers Standard Gage)
