Angle (ISA) · IS 808 · India
ISA 35x35x5 is an Indian standard angle with 35 × 35 mm legs, 5.0 mm thick, weighing 2.5 kg/m. The dimensions below are the published IS 808 values; the drawing is generated from them.
ISA angles brace and connect Indian steelwork; an angle bends about tilted principal axes, and the derived principal values below carry their angle.

Derived section properties
Integrated from a square-cornered outline — the fillet radii this family really has are not drawn, so the computed values differ slightly from published. For ISA 35x35x5 the computed area is 1.56% from published and Ix 2.02%. Where a value is also published, the published one above is the one to quote.
