Notes:<br />
1. This table is calculated in accordance with AS/NZS 4600 using design yield stress fy = 350 MPa and design tensile strength fu = 380 MPa.<br />
2. Effective section properties are calculated in accordance with AS/NZS 4600.<br />
3. All columns of the table (except for “Mass per metre” and External Surface Area”) are calculated using design thicknesses of 1.45mm and 2.4mm rather than the<br />
respective thicknesses t of 1.6mm and 2.5mm. This is to comply with clause 1.5.1.6 of AS/NZS4600.<br />
4. For Square and Rectangular Hollow Sections the outside corner radius r used in calculating the section properties is equal to 2t for sections with thickness<br />
t < 3.0mm and 2.5t for sections with t > 3.0mm.<br />
