Notes:
1. This table is calculated in accordance with AS 4100 using design yield stress fy = 350 MPa and design tensile strength fu = 430 MPa as per AS 4100 table 2.1 for
AS 1163 grade C350L0.
2. Grade C350L0 is cold formed and therefore is allocated the CF residual stresses classification in AS 4100.
3. C = Compact Section; N = Non-compact Section; S = Slender Section; as defined in AS 4100.
