TECHNICAL ENQUIRIES
Product standards are order-specific.
We do not advertise blanket product certification without the appropriate evidence.
| Customer request | What we review |
|---|---|
| Mechanical grade (yield / tensile) | Specified coil grade, supplier mill certificate, required tests and achievable manufacturing process. |
| Dimensional tolerances | Profile, wall thickness, length, test method and required acceptance limits. |
| Galvanised or ZAM coatings | Coating specification, weld-seam condition, cut-edge protection and finished-part requirements. |
| EN / ASTM or project standard | Applicable edition, clauses, certification evidence and any external tests required. |
| Export paperwork | Destination, Incoterm, available raw-material documentation and origin paperwork. |
Management-system certificates do not automatically certify individual tube batches or claim compliance with EN 10219, ASTM A500 or any other particular product specification. Written conformity claims require appropriate supporting documents.
