ISLC 300A — Dimensions & Section Properties
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.
Also known as: ISLC 300A (UK / Australia)
The ISLC 300A steel profile weighs 33.1 kg/m (22.24 lb/ft), has a depth of 300 mm (11.81 in), flange width 90 mm (3.54 in). Cross-sectional area: 3,213 mm². Moment of inertia Ix = 3,961.69 cm⁴, Iy = 195.29 cm⁴.
