Notes:<br />
1. For OneSteel-300PLUS sections the tensile strength (fu) is 440 MPa.<br />
2. For Grade 350 sections the tensile strength (fu) is 480 MPa.<br />
3. C = Compact Section; N = Non-compact Section; S = Slender Section.<br />
4. OneSteel-300PLUS hot rolled sections are produced to exceed the minimum requirements of AS/NZS 3679.1-300.<br />
5. OneSteel-300PLUS replaced Grade 250 as the base grade for these sections in 1994.<br />
