CHS 38.1x1.4 Acindar · Weight & Dimensions

Acindar, 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 38.1x1.4 steel profile weighs 1.3 kg/m (0.85 lb/ft). Cross-sectional area: 161.415 mm². Moment of inertia Ix = 2.722 cm⁴, Iy = 2.722 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 1.4 mm ≈ 16 gauge (Manufacturers Standard Gage)
