SHS 30x30x1.2 Acindar · Weight & Dimensions

Acindar, cold-formed sections · Square Hollow Section

Square Hollow Sections (SHS) are tubular profiles with equal sides, ideal for columns and compression members due to their uniform buckling resistance in all directions.

Also known as: PTR 30x30 cal 18 (México) · Caño estructural 30x30 (Argentina)

The SHS 30x30x1.2 steel profile weighs 1.1 kg/m (0.71 lb/ft), has a depth of 30 mm (1.18 in), flange width 30 mm (1.18 in). Cross-sectional area: 134.532 mm². Moment of inertia Ix = 1.833 cm⁴, Iy = 1.833 cm⁴.
