Steel grade C450L0 / C400L0 / C350L0 (for t ≤ 2.5 mm fy = 350 MPa and fu = 400 MPa, for 2.5 mm < t ≤ 6.0 mm fy = 450 MPa and fu = 500 MPa, and for t > 6.0 mm fy = 400 MPa and fu = 450 MPa). Full section properties are calculated in accordance with AS/NZS 4600. Sizes shown in Italics may not be stocked in all states or minimum order quantities may apply. # are also available as DuraGal® Plus (Lintels). 150 x 10 x 6.0 CA is a preferred Lintel size.
