Quality Assurance

How We Earn Your Trust

The Chinese steel market is plagued by trust gaps — fake certificates, weight shortages, "head and tail compliant, middle inferior" coating fraud. Our entire operating model is designed to eliminate those risks. Here's how.

Four Trust Pillars

Live Certificate Verification

Every ISO, CE, and Mill Test Report (EN 10204 type 3.1) includes a QR code linking to the issuer's verification database. No paper-only certs that can be forged.

Heat-Number Traceability

Every coil ships with the original mill heat number physically tagged. The heat number appears on the MTR and in our customer portal — chemistry traceable to the original melt batch.

Triple-Point Coating Inspection

For every galvanized and galvalume coil, coating thickness is measured at three points (head / middle / tail). Results photographed and uploaded to your portal pre-shipment.

Third-Party Inspection Welcomed

We have established working relationships with SGS, Bureau Veritas, and Intertek. For first-time orders, we share inspection costs 50/50. Independent verification — at our suggestion, not just permission.
