ISJC 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 ISJC 125 steel profile weighs 7.9 kg/m (5.31 lb/ft), has a depth of 125 mm (4.92 in), flange width 50 mm (1.97 in). Cross-sectional area: 648 mm². Moment of inertia Ix = 150.35 cm⁴, Iy = 14.01 cm⁴.
