Notes:
1. In this table, the properties of these products are calculated in accordance with AS/NZS 4600 using design yield stress fy = 350 MPa and design tensile strength fu = 380 MPa.
2. Effective section properties are calculated in accordance with AS/NZS 4600.
3. All columns of the table (except for “Mass per metre” and “External Surface Area per t”) are calculated using design thicknesses of 1.1mm, 1.9mm, 2.2mm and 2.5mm rather
than the respective thicknesses t of 1.2mm, 2.0mm, 2.3mm and 2.6mm. This is to comply with clause 1.5.1.6 of AS/NZS 4600.
