ISMC 125
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 125 (UK / Australia)
The ISMC 125 steel profile weighs 13.1 kg/m (8.80 lb/ft), has a depth of 125 mm (4.92 in), flange width 65 mm (2.56 in). Cross-sectional area: 1,267.2 mm². Moment of inertia Ix = 302.57 cm⁴, Iy = 47.17 cm⁴.
