Equal Angle · AS/NZS 3679.1 · Australia / New Zealand
200 x 200 x 13 EA is an equal angle with 200 × 200 mm legs, 13.0 mm thick, weighing 40.0 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 200 x 200 x 13 EA the computed area agrees with the published value to better than 0.01% and Ix to 0.11%. Where a value is also published, the published one above is the one to quote.
