RHS 60×40 — Weight & Section Properties
rectangular hollow section (RHS) per EN 10219 (cold formed)
RHS 60×40 is a rectangular hollow section (RHS) with an outside dimension of 60×40 mm, available in wall thicknesses of 2.5, 3, 4, 5 mm — from 3.6 to 6.56 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 60×40 weigh?
It depends on the wall thickness: from 3.6 kg/m at t = 2.5 mm up to 6.56 kg/m at t = 5 mm. With the common t = 4 mm it weighs 5.45 kg/m — a 6 m bar is 32.7 kg.
Which wall thicknesses does RHS 60×40 come in?
The standard EN 10219 program for 60×40 mm covers t = 2.5, 3, 4, 5 mm. Other thicknesses exist by mill order; stockholders typically carry the ones in this table.
Which standard defines RHS 60×40?
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
