CHS 114.3x3.75 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 114.3x3.75 steel profile weighs 10.2 kg/m (6.87 lb/ft). Cross-sectional area: 1,302.387 mm². Moment of inertia Ix = 199.19 cm⁴, Iy = 199.19 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 3.75 mm ≈ 9 gauge (Manufacturers Standard Gage)
