Angle (ISA) · IS 808 · India
ISA 110x110x12 is an Indian standard angle with 110 × 110 mm legs, 12.0 mm thick, weighing 19.2 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 110x110x12 the computed area is 1.88% from published and Ix 1.73%. Where a value is also published, the published one above is the one to quote.
