CHS 80x2 NBE EA-95 · Weight & Dimensions

NBE EA-95, 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 80x2 steel profile weighs 3.9 kg/m (2.59 lb/ft). Cross-sectional area: 490.088 mm². Moment of inertia Ix = 37.296 cm⁴, Iy = 37.296 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2 mm ≈ 14 gauge (Manufacturers Standard Gage)
