Start with the paperwork — don’t skip certs

Always ask for mill test reports (MTRs), chemical and mechanical test results, and batch traceability. Genuine suppliers provide clear documentation showing grade, heat number, and compliance with standards (ASTM, EN, etc.). If paperwork is missing or vague, treat the material as suspect.

Inspect markings, packaging, and traceability

Real steel usually bears stamps or heat numbers that match the MTRs. Check coil/plate tags, packaging, and shipping labels for consistent information. QR codes or online trace links are becoming common — scan them and verify the batch online. Inconsistent or missing IDs are red flags.

Quick physical checks you can do on-site

Simple on-the-spot checks help: verify surface finish and dimensions, look for unusual scale or uneven coating, and perform basic tests like the spark test for carbon content or a magnet test for stainless types. For any doubt, request a handheld alloy analyzer reading or send a small sample for lab analysis.

Vet suppliers and use independent inspection

Buy only from reputable suppliers with verifiable references. Third-party inspection (pre-shipment NDT, dimensional checks, coating thickness measurement) reduces risk. Ask for supplier audit records and recent quality-control photos. A trustworthy vendor welcomes scrutiny — counterfeiters avoid it.
