ISMC 250
IS — 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: ISMC 250 (UK / Australia)
The ISMC 250 steel profile weighs 34.2 kg/m (22.98 lb/ft), has a depth of 250 mm (9.84 in), flange width 82 mm (3.23 in). Cross-sectional area: 3,483 mm². Moment of inertia Ix = 2,958.66 cm⁴, Iy = 168.83 cm⁴.
