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<br />
quantity may apply on some sizes. Please contact your local Steel & Tube branch for information and availability on these sizes.<br />
Notes:<br />
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 =<br />
400 MPa and fu = 450 MPa).<br />
2. Ae is calculated for sections with uniform axial compressive stress fy.<br />
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.<br />
4. Iex1 and Zex1 are for compression at point “1”; Iex4 and Zex4 are for compression at point “4”; Iey2,3 and Zey2,3 are for compression at points “2” and “3”; Iey5 and Zey5<br />
are for compression at point “5”.<br />
5. Effective section properties are calculated in accordance with AS/NZS 4600.<br />
