L 30x30x4
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 30x30x4 steel profile weighs 1.8 kg/m (1.20 lb/ft), has a depth of 30 mm (1.18 in), flange width 30 mm (1.18 in). Cross-sectional area: 224 mm². Moment of inertia Ix = 1.86 cm⁴, Iy = 1.86 cm⁴.
