CHS 34.92x1.06 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 34.92x1.06 steel profile weighs 0.9 kg/m (0.60 lb/ft). Cross-sectional area: 112.757 mm². Moment of inertia Ix = 1.618 cm⁴, Iy = 1.618 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 1.06 mm ≈ 18 gauge (Manufacturers Standard Gage)
