RHS 150×100 — Weight & Section Properties
rectangular hollow section (RHS) per EN 10219 (cold formed)
RHS 150×100 is a rectangular hollow section (RHS) with an outside dimension of 150×100 mm, available in wall thicknesses of 5, 6, 8, 10 mm — from 18.3 to 33.4 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 150×100 weigh?
It depends on the wall thickness: from 18.3 kg/m at t = 5 mm up to 33.4 kg/m at t = 10 mm. With the common t = 8 mm it weighs 27.7 kg/m — a 6 m bar is 166.2 kg.
Which wall thicknesses does RHS 150×100 come in?
The standard EN 10219 program for 150×100 mm covers t = 5, 6, 8, 10 mm. Other thicknesses exist by mill order; stockholders typically carry the ones in this table.
Which standard defines RHS 150×100?
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
