CHS 48x5.08 IMCA · Weight & Dimensions

IMCA, 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 48x5.08 steel profile weighs 5.4 kg/m (3.62 lb/ft). Cross-sectional area: 684.973 mm². Moment of inertia Ix = 15.994 cm⁴, Iy = 15.994 cm⁴.

Cross-section (not to scale)

Gauge equivalent: 5.08 mm ≈ 6 gauge (Manufacturers Standard Gage)
