Terms of use

By using MetalCalc Pro you agree to these terms. If you do not agree, please stop using the service.

The calculators and reference pages are provided “as is” without warranties of any kind. Mass estimates are for planning and logistics only—not for structural certification, regulated safety decisions, or legal metrology.

• You remain responsible for verifying all results against official standards, drawings, and mill certificates.
• We may change, suspend, or discontinue features to maintain security or improve accuracy.
• You must not attempt to disrupt the service, probe it beyond normal use, or scrape it in a way that degrades performance for others.
• Links to third-party app stores and social profiles leave our site; those services have their own terms.

To the maximum extent permitted by law, we are not liable for indirect or consequential damages arising from use of the calculators. Some jurisdictions do not allow certain limitations; in those cases our liability is limited to the fullest extent still permitted.
