ISLC 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.
The ISLC 400 steel profile weighs 45.8 kg/m (30.78 lb/ft), has a depth of 400 mm (15.75 in), flange width 100 mm (3.94 in). Cross-sectional area: 4,608 mm². Moment of inertia Ix = 9,671.37 cm⁴, Iy = 317.47 cm⁴.
