This table is calculated in accordance with AS 4100 using design yield stress fy = 450 MPa and design tensile strength fu = 500 MPa as per AS 4100 table 2.1 for AS 1163 grade C450L0. Grade C450L0 is cold formed and therefore is allocated the CF residual stresses classification in AS 4100. C = Compact Section; N = Non-compact Section; S = Slender Section; as defined in AS 4100. 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 t ≤ 3.0mm and 2.5t for sections with t > 3.0mm.
