SHS 30x30x0.9 Cimagbo · Weight & Dimensions

Cimagbo, 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 30x30x0.9 steel profile weighs 0.8 kg/m (0.54 lb/ft), has a depth of 30 mm (1.18 in), flange width 30 mm (1.18 in). Cross-sectional area: 102.674 mm². Moment of inertia Ix = 1.434 cm⁴, Iy = 1.434 cm⁴.
