CHS 47.62x1.95 Gerdau · Weight & Dimensions

Gerdau, tubes · 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 47.62x1.95 steel profile weighs 2.2 kg/m (1.48 lb/ft). Cross-sectional area: 279.779 mm². Moment of inertia Ix = 7.308 cm⁴, Iy = 7.308 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 1.95 mm ≈ 14 gauge (Manufacturers Standard Gage)
