Verify Genuine RS Steel

Verify markings, tags, and documentation to confirm genuine products.

To confirm you have received genuine RS Steel, check the rolled-in bar markings, the rib pattern, the bundle tag, the diameter and weight per metre, and request the mill test certificate (MTC).

How to verify genuine RS Steel

Use these checks at delivery before fixing steel.

  1. Check the bar markings: Look for the rolled-in RS / manufacturer identification and grade marking along the bar.
  2. Inspect the rib pattern: Confirm a consistent, well-formed rib geometry along the length of every bar.
  3. Verify the bundle tag: Match the bundle tag to the delivery note and check size, grade, and batch details.
  4. Measure size and weight: Confirm the diameter and weight per metre against the expected values for the size.
  5. Request the mill test certificate: Ask for the MTC to confirm mechanical properties and chemistry for the batch.
