ISMC 400
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 400 (UK / Australia)
The ISMC 400 steel profile weighs 50.1 kg/m (33.67 lb/ft), has a depth of 400 mm (15.75 in), flange width 100 mm (3.94 in). Cross-sectional area: 5,047.7 mm². Moment of inertia Ix = 10,532.46 cm⁴, Iy = 341.1 cm⁴.
