DX51D+Z — chemical composition
| Element | Maximum / range (% by mass) |
|---|---|
| C | ≤0.180 |
| Mn | ≤1.20 |
| P | ≤0.120 |
| S | ≤0.045 |
| Si | ≤0.50 |
| Ti | ≤0.300 |
Heat analysis limits; the ordered standard edition and grade take precedence.
DX51D+Z — mechanical properties
| Thickness (mm) | Tensile strength Rm (MPa) | Elongation A80 min. (%) |
|---|---|---|
| 0.20–0.35 | 270–500 | 15 |
| >0.35–0.50 | 270–500 | 18 |

Transverse specimens. No minimum yield strength is specified for DX51D in this table. Confirm the test timing and ordered standard.
Zinc coating designations
| Designation | Minimum total mass, both sides (g/m²) | Basis |
|---|---|---|
| Z100 | 100 | Three-spot test |
| Z120 | 120 | Three-spot test |
| Z140 | 140 | Three-spot test |
| Z180 | 180 | Three-spot test |
| Z200 | 200 | Three-spot test |
| Z225 | 225 | Three-spot test |
| Z275 | 275 | Three-spot test |
Coating mass is separate from base-steel grade; Z275 is not a strength grade. Do not treat ASTM G90 and EN Z275 as identical acceptance specifications.
Zinc spangle and surface treatment
| Property | Available specification |
|---|---|
| Spangle | Zero, minimized, normal or large spangle; specify appearance |
| Finish | Skin-passed or as-coated surface |
| Passivation | Chromated or specified chromium-free treatment |
| Oiling | Oiled or dry; confirm compatibility with subsequent processing |
| Further processing | Slitting, cut-to-length, bending or punching to the agreed drawing |
Treatment and appearance are order options; not every combination is available for every grade and coating mass.
Surface & processing requirements
Include the downstream process in your enquiry so that the material, dimensions and surface can be reviewed together.
| Slitting requirements | Target strip width, edge condition and winding arrangement. |
|---|---|
| Forming / fabrication | Describe the downstream forming, pressing, profiling or fabrication operation. |
| Coating & treatment | Confirm the metallic coating and any post-treatment alongside the forming requirements. |
| Coil handling | Confirm lifting, uncoiling and storage constraints. |
Production & processing
Define the material and the downstream process together. Cutting, slitting or finishing requirements should form part of the order specification.
Material review
Grade, dimensions and surface requirements are checked against the enquiry.
Processing scope
Agree cutting, slitting or forming requirements and the finished product tolerances.
Order inspection
Define acceptance criteria, identification and the requested documentation.
Stock & warehouse
Hot rolled, galvanized and color coated material in warehouse settings. Ask our team to confirm current availability for your grade, dimensions and quantity.
Quality inspection & documentation
Agree the acceptance criteria and required documents before confirming your order.
- Material identificationGrade, standard and requested test documentation.
- Dimensions & surfaceThickness, width, finish and agreed tolerances.
- Order documentsProduct identification, packing list and inspection scope.
Packaging & shipment
Tell us how the material will be transported, unloaded and stored. Specify moisture protection, edge protection, package weight and destination with your enquiry.
| Protection | Moisture barrier, edge protection and surface protection as agreed. |
|---|---|
| Unit weight | Specify the coil or bundle weight for your unloading equipment. |
| Identification | Product, grade, dimensions and order reference on the agreed packing list. |
| Delivery | Confirm destination, transport method and delivery terms in the quotation. |
Certificates & verification documents
Request the original document issued for the supplying company, product scope and order. Material test reports and conformity documents are checked against the named holder, issuing body and validity period.
| Material test report | Heat or coil number, ordered grade, chemical composition and mechanical test results. |
|---|---|
| Inspection document | Specify the required EN 10204 document type and inspection scope in the enquiry. |
| Conformity documents | Request an original copy showing the issuing body, holder, number, applicable scope and validity. |
Frequently asked questions
What should I include in my enquiry?
Send the product, grade or standard, dimensions, quantity, required finish and destination. Describe the end use if the specification is still being developed.
Can I request a particular size or finish?
Yes, include your required size and finish in the enquiry. Availability and any processing requirements must be confirmed in the quotation.
How are minimum order and lead time confirmed?
They depend on grade, dimensions, processing and quantity. We confirm them for the particular order rather than publish one figure for every product.
What documents should I request?
State the material test document, inspection scope and other purchasing documents required for your project. Agree these with the order.
