RHS 120×60 — Weight & Section Properties
rectangular hollow section (RHS) per EN 10219 (cold formed)
RHS 120×60 is a rectangular hollow section (RHS) with an outside dimension of 120×60 mm, available in wall thicknesses of 4, 5, 6 mm — from 10.5 to 15.1 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 RHS 120×60 weigh?
It depends on the wall thickness: from 10.5 kg/m at t = 4 mm up to 15.1 kg/m at t = 6 mm. With the common t = 5 mm it weighs 12.8 kg/m — a 6 m bar is 76.8 kg.
Which wall thicknesses does RHS 120×60 come in?
The standard EN 10219 program for 120×60 mm covers t = 4, 5, 6 mm. Other thicknesses exist by mill order; stockholders typically carry the ones in this table.
Which standard defines RHS 120×60?
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
