CHS 88.9x3.35 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 88.9x3.35 steel profile weighs 7.1 kg/m (4.75 lb/ft). Cross-sectional area: 900.357 mm². Moment of inertia Ix = 82.495 cm⁴, Iy = 82.495 cm⁴.
Cross-section (not to scale)
Gauge equivalent: 3.35 mm ≈ 10 gauge (Manufacturers Standard Gage)
