ISLC 250
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 250 steel profile weighs 28.0 kg/m (18.82 lb/ft), has a depth of 250 mm (9.84 in), flange width 100 mm (3.94 in). Cross-sectional area: 2,633.4 mm². Moment of inertia Ix = 2,441.58 cm⁴, Iy = 227.3 cm⁴.
