CHS 139.7x4.9 Iberian tables · Weight & Dimensions

Iberian tables, cold-formed sections · Circular Hollow Section

Circular Hollow Sections (CHS) are round tubular profiles with the most efficient cross-section for compression. Used for columns, trusses, and architectural structures.

Also known as: Caño estructural redondo (Argentina)

The CHS 139.7x4.9 steel profile weighs 16.3 kg/m (10.95 lb/ft). Cross-sectional area: 2,075.085 mm². Moment of inertia Ix = 471.953 cm⁴, Iy = 471.953 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 4.9 mm ≈ 7 gauge (Manufacturers Standard Gage)
