About MetalCalc Pro

MetalCalc Pro is a focused engineering tool for estimating the mass of common metal profiles—pipes, plates, bars, mesh, flanges, and more—using catalog densities and clear geometry models.

The same calculation philosophy powers our web calculators and the Metal Calculation mobile apps for iOS and Android, so you can cross-check estimates between the office and the shop floor.

We are not a substitute for mill certificates, structural design software, or official standard tables. Our outputs are indicative: always verify mass and dimensions against your supplier documentation before purchase or structural sign-off.

If you spot a discrepancy with a standard you rely on, please contact us with the profile, grade, and reference document—we use that feedback to improve catalog coverage and wording.
