ISLC 125A
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 125A steel profile weighs 11.3 kg/m (7.59 lb/ft), has a depth of 125 mm (4.92 in), flange width 65 mm (2.56 in). Cross-sectional area: 1,109.5 mm². Moment of inertia Ix = 268.38 cm⁴, Iy = 42.29 cm⁴.
