ISJC 100

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 100 steel profile weighs 5.8 kg/m (3.90 lb/ft), has a depth of 100 mm (3.94 in), flange width 45 mm (1.77 in). Cross-sectional area: 543 mm². Moment of inertia Ix = 82.11 cm⁴, Iy = 9.68 cm⁴.
