ISLC 125
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 125 steel profile weighs 10.7 kg/m (7.19 lb/ft), has a depth of 125 mm (4.92 in), flange width 65 mm (2.56 in). Cross-sectional area: 1,063.9 mm². Moment of inertia Ix = 258.31 cm⁴, Iy = 40.82 cm⁴.
