L 20x20x3
EN — Angle Section
Angle sections (L shapes) are used for bracing, connections, lintels, and built-up members. Available in equal and unequal leg configurations.
The L 20x20x3 steel profile weighs 0.9 kg/m (0.59 lb/ft), has a depth of 20 mm (0.79 in), flange width 20 mm (0.79 in). Cross-sectional area: 111 mm². Moment of inertia Ix = 0.4 cm⁴, Iy = 0.4 cm⁴.
