Definition & Overview of Galvanized Steel Coil DX51D+Z CIF Tianjin
DX51D+Z is a common grade per EN 10346 for hot‑dip galvanized steel with continuous zinc coating. Orders define thickness/width, coating mass (e.g., Z100–Z275), spangle (regular/minimized/zero), oiling/passivation, surface class and flatness aligned to downstream uses (forming, profiling, ducting).
Bundle HDGI with upstream/downstream materials for freight efficiency: Cold Rolled Sheet, profiles and tubes via Hollow Section and Pipe; project steel via Angle, U‑Channel and I‑Beam & H‑Beam.
Specifications & Sizes (Thickness / Width / Coating / Coil Data)
Indicative ranges—confirm exact windows in RFQ and order. Coating, surface and flatness classes impact performance and price.
| Parameter | Typical Range | Coating Mass | Spangle | Surface / Passivation | Coil ID (mm) | Coil Weight (t) | Notes |
| Thickness (mm) | 0.30–2.50 | Z100–Z275 (indic.) | Reg/Min/Zero | Oiled / Passivated | 508 / 610 | 10–25 (typ.) | Trim/slit per order |
| Width (mm) | 800–1500 (typ.) | — | — | — | 508 / 610 | 10–25 (typ.) | Narrow widths on request |
| Surface class | A/B (indic.) | — | — | Per EN/mill tables | — | — | Skin‑pass optional |
Grade Mapping & Context (DX51D+Z)
| Standard | Comparable | Use Case | Notes |
| EN 10346 DX51D+Z | ASTM A653 CS Type B (approx.) | General forming/profiling | Confirm mechanicals per thickness |
| — | JIS G3302 SGCC (approx.) | General galvanizing quality | Surface classes differ |
| — | DX52D/DX53D | Higher formability | Specify explicitly if needed |
Downstream options include fabrication or coating systems: Round Bar & Flat Bar, Hollow Section, plus upstream feed from Hot Rolled Sheet and Cold Rolled Sheet.
Mechanical & Flatness (indicative – per MTC)
| Property | Typical / Minimum | Method | Notes |
| Yield Strength (MPa) | Per EN table/MTC | Per EN/MTC | Depends on base CRC |
| Tensile Strength (MPa) | Per EN table/MTC | Per EN/MTC | — |
| Elongation % | Per EN table/MTC | Per EN/MTC | Gauge length per standard |
| Flatness/Camber | Per mill class | — | Tighter classes add cost |
Applications / Market Use Cases
Roofing and cladding profiles, HVAC/ducting, light structural components, cabinets and enclosures, automotive non‑critical parts, and fabrication after profiling.
Pricing Drivers for Galvanized Steel Coil DX51D+Z CIF Tianjin (CIF Tianjin)
| Driver | Impact | Notes |

Logistics, Packaging & Delivery (CIF Tianjin → Europe)
Coils are strapped and tagged; under CIF Tianjin the ocean freight and insurance are seller‑arranged for Tianjin delivery. Parallel quotations for CIF Italy (e.g., Genoa/Trieste) and CIF Germany (e.g., Hamburg/Bremerhaven) can be issued on request to support European programs.
Bundle HDGI with other steel cargo to optimize landed cost: Rebar, Wire Rod, I‑Beam & H‑Beam, U‑Channel and Angle.
Quality Assurance, MTC & Inspections
Each lot ships with MTC (chemistry/mechanicals), coating mass verification and surface/flatness data per order. Third‑party inspection at mill/port can witness sample coating tests and dimensional checks.
For upstream casting/rolling context see Billet Grades and process notes under Wire Rod Production.
Supplier Selection Tips
Shortlist exporters with stable galvanizing lines, consistent coating mass and surface quality, and proven export packing. Trial parcels validate profiling and paint adhesion before scale‑up.

RFQ Checklist
- Confirm grade and standard: EN 10346 DX51D+Z; specify higher formability (DX52D/DX53D) if needed.
- State thickness/width, coating mass (e.g., Z100–Z275), spangle class, surface class and oiling/passivation.
- Define coil ID/OD and target coil weight with coil count.
- Incoterms: CIF Tianjin (base); request CIF offers to Italy/Germany if required.
- Specify coil tagging/marking and moisture protection (VPI/oil).
- Monthly/annual tonnage and dispatch calendar; allow split lots if helpful.
- Set QA/TPI scope, sampling and acceptance rules, including coating tests.
FAQ
Q: Can you quote CIF Tianjin and also CIF Italy/Germany?
A: Yes—parallel quotations help benchmark landed costs and schedules.
Q: Do you supply zero‑spangle or minimized‑spangle HDGI?
A: Yes—both options are available; include in your RFQ.
Q: What coil IDs and weights are typical?
A: 508 or 610 mm IDs; 10–25 t coil weights are common—confirm at RFQ.
