ISMC 100
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 100 (UK / Australia)
The ISMC 100 steel profile weighs 9.6 kg/m (6.42 lb/ft), has a depth of 100 mm (3.94 in), flange width 50 mm (1.97 in). Cross-sectional area: 925 mm². Moment of inertia Ix = 137.35 cm⁴, Iy = 19.39 cm⁴.
