RHS / SHS Weight Calculator

Calculate theoretical mass for rectangular or square hollow steel sections.

How it works

Calculate theoretical mass for rectangular or square hollow steel sections.

Core method:
Steel area = B×H − (B−2t)(H−2t). Mass = area × length × density. Corner radii are ignored.

Before you use the result: Check project drawings, supplier data and site conditions before ordering materials.

Practical use

Enter dimensions from the latest drawings or verified site measurements. Adjust allowances and material properties to the supplier or specification you are actually using. Results update instantly as inputs change.

Keep units consistent with the source information.
Use project-specific densities, pack sizes and coverage rates where provided.
Round purchasing quantities to supplier packaging and delivery rules.
