ISLC 300
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 300 steel profile weighs 33.1 kg/m (22.24 lb/ft), has a depth of 300 mm (11.81 in), flange width 100 mm (3.94 in). Cross-sectional area: 3,215.3 mm². Moment of inertia Ix = 4,097.96 cm⁴, Iy = 257.71 cm⁴.
