SHS 180x180x4 Iberian tables · Weight & Dimensions

Iberian tables, 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 180x180 cal 8 (México) · Caño estructural 180x180 (Argentina)

The SHS 180x180x4 steel profile weighs 21.8 kg/m (14.64 lb/ft), has a depth of 180 mm (7.09 in), flange width 180 mm (7.09 in). Cross-sectional area: 2,774.796 mm². Moment of inertia Ix = 1,421.744 cm⁴, Iy = 1,421.744 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4 mm ≈ 8 gauge (Manufacturers Standard Gage)
