ISLC 350
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 350 steel profile weighs 38.9 kg/m (26.14 lb/ft), has a depth of 350 mm (13.78 in), flange width 100 mm (3.94 in). Cross-sectional area: 3,905.7 mm². Moment of inertia Ix = 6,501.9 cm⁴, Iy = 289.79 cm⁴.
