CHS 50x2.5 Hiasa · Weight & Dimensions

Hiasa, 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 50x2.5 steel profile weighs 2.9 kg/m (1.97 lb/ft). Cross-sectional area: 373.064 mm². Moment of inertia Ix = 10.551 cm⁴, Iy = 10.551 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 2.5 mm ≈ 12 gauge (Manufacturers Standard Gage)
