SinoBarrier ships every guardrail and roller barrier order with the certification paper a procurement team asks for. Two credentials matter most to highway projects, and both are produced and verified on our floor.
Our certifications
- AASHTO M180 — hot-dip galvanized corrugated sheet steel beam, 550 g/m² minimum coating weight. See the AASHTO M180 detail.
- MASH TL3 / TL4 — full-scale crash testing of the assembled barrier system, for W-beam, thrie-beam and roller barrier configurations.
- EN 1317 / CE — the European standard for projects supplied into the EU, with CE documentation.
What you receive with an order
- Mill test certificate for the base metal

If a tender requires a certificate pack before you place the order, send the item number and quantity and we return the documents with your quotation.
