ISA 25x25x3
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 25x25x3 steel profile weighs 1.1 kg/m (0.74 lb/ft), has a depth of 25 mm (0.98 in), flange width 25 mm (0.98 in). Cross-sectional area: 141 mm². Moment of inertia Ix = 0.82 cm⁴, Iy = 0.82 cm⁴.
