IS — Angle Section
Angle sections (L shapes) are used for bracing, connections, lintels, and built-up members. Available in equal and unequal leg configurations.
The ISA 120x120x12 steel profile weighs 21.6 kg/m (14.52 lb/ft), has a depth of 120 mm (4.72 in), flange width 120 mm (4.72 in). Cross-sectional area: 2,736 mm². Moment of inertia Ix = 373.26 cm⁴, Iy = 373.26 cm⁴.
