F DuraGal Unequal Angles are not a common stock item but sizes 100 x 75, 125 x 75, 150 x 100 in 6 or 8mm wall thickness are also available on request. A minimum order
quantity may apply on some sizes. Please contact your local Steel & Tube branch for information and availability on these sizes.
Notes:
1. Steel grade C450L0 / C400L0 / C350L0 (for t < 2.5mm fy = 350 MPa and fu = 400 MPa, for 2.5mm < t < 6.0mm fy = 450 MPa and fu = 500 MPa, and for t > 6.0mm fy =
400 MPa and fu = 450 MPa).
2. Ae is calculated for sections with uniform axial compressive stress fy.
3. Ie and Ze are calculated with the extreme compression or tension fibres at fy (first yield). Ze is calculated at the extreme tension or compression fibre of the effective section.
4. IenT and ZenT are for compression at point “T”; IenB and ZenB are for compression at point “B”; IepR and ZepR are for compression at point “R”; IepL and ZepL
are for compression at point “L”.
5. Effective section properties are calculated in accordance with AS/NZS 4600.
