25 x 25 x 6 EA

Equal Angle · AS/NZS 3679.1 · Australia / New Zealand

25 x 25 x 6 EA is an equal angle with 25 × 25 mm legs, 6.0 mm thick, weighing 2.1 kg/m. The dimensions below are the published AS/NZS 3679.1 values; the drawing is generated from them.

Equal Angles serve as bracing, cleats and lintels. An unrestrained angle bends about its tilted principal axes, so the published Imin — not Ix — governs its buckling checks.

Derived section properties

Integrated from the section's own outline including the root and toe radii, whose arcs are integrated analytically rather than approximated by facets. For 25 x 25 x 6 EA the computed area agrees with the published value to 0.19% and I_x to better than 0.01%. Where a value is also published, the published one above is the one to quote.
