Notes:<br />

1. Steel grade C450L0 / C400L0 (for t < 6.0mm fy = 450 MPa and fu = 500 MPa, and for t > 6.0mm fy = 400 MPa and fu = 450 MPa).<br />

2. With the exception of J, properties are calculated assuming a simplified shape where the bends are eliminated and the section is represented by straight mid-lines in<br />

accordance with Clause 2.1.2.1 of AS/NZS 4600.<br />

3. ß x is zero for channels.<br />
