Mill Certificate and Material Verification Agent

Verify delivered steel and rebar against specification and mill certificates before acceptance

Mill Certificate and Material Verification Agent: what goes in, what the agent does and what you get

What it does

Delivered steel does not always match the specified grade, and the paperwork arrives after the material is installed. The agent reads each delivery ticket and mill certificate and compares them with the specification. It checks the grade, size, heat numbers and chemistry limits, and matches heat numbers on the certificate with those on the ticket. It flags mismatches and drafts requests for missing or unclear documents. After updates arrive, it rechecks. It recommends acceptance, further testing or rejection for each lot. The engineer approves each decision. Edge case: a certificate shows carbon above the limit for the grade, so the agent recommends testing and holds the lot.

How it works

Follow the arrows from top to bottom. The orange dashed arrow is the loop: when a check fails, the agent goes back and tries again.

How it decides

Material passes only if grade, heat number and chemistry match the specification and the delivery tag.

  • Require one certificate for each heat number
  • Reject a lot whose grade differs from the specification
  • Recommend testing if chemistry is within 5% of a limit
  • Hold lots without certificates from release to the fabricator

Make it yours

Every agent is a starting point. You choose these settings for your own situation.

  • Specifications checked
  • Test trigger margin (default 5%)
  • Supplier contacts
  • Hold rules for lots

What keeps you in control

It always asks you first

  • Engineer approves supplier requests
  • Engineer approves acceptance, testing or rejection

Hard limits

  • Never release a lot without engineer approval
  • Never infer a certificate value that is missing

It stops when

  • Done: every lot is accepted or has an approved remedy
  • Stop: material is already installed without paperwork and the engineer must decide

An example run

What happensA delivery of #5 rebar showed grade 60 on the ticket but a certificate for grade 40 under the same heat number. The agent flagged the lot and requested a corrected certificate. The new certificate showed grade 60 but listed a different heat. It checked again, found a mismatch, and recommended testing. The engineer approved a tensile test.
