EN 10025 S235 S275 S355 Steel Grades
Buyer guide for common EN structural steel plate grades.
Practical Standard Review
EN structural grades should be ordered with grade, impact suffix, thickness range, delivery condition, certificate type, and any project approval requirement. The suffix can matter as much as the base grade.
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 | EN structural grades should be ordered with grade, impact suffix, thickness range, delivery condition, certificate type, and any project approval requirement. The suffix can matter as much as the base grade. |
|---|---|
| Confirm in RFQ | S235, S275, S355, JR/J0/J2, thickness, delivery condition, MTC, and inspection |
| Risk to avoid | A simple S355 request may not define impact requirement or delivery condition. |
| 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.
