ISA 80x80x8
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 80x80x8 steel profile weighs 9.6 kg/m (6.45 lb/ft), has a depth of 80 mm (3.15 in), flange width 80 mm (3.15 in). Cross-sectional area: 1,216 mm². Moment of inertia Ix = 73.73 cm⁴, Iy = 73.73 cm⁴.
