CHS 273 — Weight & Section Properties
circular hollow section (CHS) per EN 10219 (cold formed)
CHS 273 is a circular hollow section (CHS) with an outside dimension of Ø 273 mm, available in wall thicknesses of 5, 6, 8, 10, 12.5 mm — from 33 to 80.3 kg per meter. The table below lists weight and section properties for every standard thickness, computed from the exact EN 10219-2 corner geometry (7,850 kg/m³).
Typical uses: frames, columns, railings, machine bases, and general steel construction. Every row can be checked in the weight or deflection calculator with one click below.

Frequently Asked Questions
How much does CHS 273 weigh?
It depends on the wall thickness: from 33 kg/m at t = 5 mm up to 80.3 kg/m at t = 12.5 mm. With the common t = 8 mm it weighs 52.3 kg/m — a 6 m bar is 313.8 kg.
Which wall thicknesses does CHS 273 come in?
The standard EN 10219 program for Ø 273 mm covers t = 5, 6, 8, 10, 12.5 mm. Other thicknesses exist by mill order; stockholders typically carry the ones in this table.
Which standard defines CHS 273?
These values follow EN 10219 (cold formed structural hollow sections) with its corner geometry — outer radius 2t, 2.5t or 3t depending on wall thickness. Hot finished equivalents per EN 10210 have tighter corners and marginally different weights and properties.
Values are entered from the governing standard’s published tables and cross-checked programmatically against its mass and section formulas before publication. Spotted an error? Write to advertising@metalabout.net — verified corrections ship within days. About
