ASTM A500 vs EN 10219 Hollow Section
Compare common hollow section ordering references for structural tubes.
Practical Standard Review
ASTM A500 and EN 10219 RFQs use different grade names and dimension conventions. A quotation should confirm shape, size, wall thickness, length, straightness, coating, weld seam control, and certificate requirement.
Himount Steel reviews the ordered standard, grade, product form, dimension tolerance, inspection level, packing method, and shipment route before confirming price and lead time. Final supply always follows the buyer specification and accepted mill test certificate.
Key Ordering Points
| Main comparison | ASTM A500 and EN 10219 RFQs use different grade names and dimension conventions. A quotation should confirm shape, size, wall thickness, length, straightness, coating, weld seam control, and certificate requirement. |
|---|---|
| Confirm in RFQ | standard, grade, square or rectangular size, wall thickness, length, tolerance, and surface |
| Risk to avoid | Do not treat Gr.B, Gr.C, S235JRH, and S355JRH as automatic equivalents. |
| Documentation | Confirm MTC type, heat number traceability, inspection record, and any buyer approval wording. |
| Next step | Send the project specification or previous PO so Himount Steel can check the supply route. |
Buyer Checks Before Quotation
- Use the project specification as the authority when grade names look similar.
- Confirm product form, size, tolerance, delivery condition, and inspection plan together.
- Ask for comparable references only as RFQ aids, not automatic substitutions.
- Review certificate wording before shipment if the project has strict acceptance rules.
