EN S355 Mild Steel Supplier in India
Rubinox Metal and Alloys supports EN S355 Mild Steel enquiries for higher-strength European structural plates, sections and fabrication steel. Buyers can share grade, standard, product form, dimensions, quantity, condition, testing, documentation requirement and delivery location for specification-led RFQ review.

EN S355 Mild Steel Overview
EN S355 is a European structural steel grade commonly reviewed where projects require higher structural strength than lower-strength mild steel grades. Rubinox supports RFQs for plates, sections, angles, channels, flats and fabrication steel based on standard, subgrade, size, quantity and documentation requirement.
Common Product Forms
- Plates, sheets and structural sections
- Angles, channels, flats and project steel forms
- Cut-to-size plates and fabricated blanks
- BOQ, drawing or MTO-based project requirements
Standards and Specification Guidance
- Confirm EN 10025 S355 and the required subgrade such as JR, J0 or J2 where applicable.
- Share thickness, dimensions, section size, tolerance and delivery condition.
- Do not substitute S355 with S235 or A36 without buyer or project engineer approval.
- State MTC, impact testing, UT, dimensional inspection or packing requirements where applicable.
Applications
- Higher-strength structural frames and supports
- Infrastructure, fabrication and engineering projects
- Equipment bases, platforms and structural assemblies
- Project steelwork where EN S355 is specified
- Maintenance and replacement structural components
S355 Structural Guidance
S355 is selected when the project calls for higher structural strength. Buyers should confirm EN subgrade, impact requirements, delivery condition and whether any alternate grade is acceptable.
Documentation and Inspection Notes
- State MTC and traceability requirements in the RFQ where applicable.
- Mention PMI, dimensional inspection, impact testing or third-party inspection only when required by the project.
- Share marking, packing, cutting and dispatch preferences before quotation.
- Final acceptance should follow buyer, consultant or project specification.
