DX51D Z275 galvanized steel is commonly used in building structures or industrial equipment that require high corrosion resistance, it is a popular material grade for cold forming in EN 10346 standard, Wanzhi Group is a steel supplier from China, we can produce ISO-certified galvanized steel material that serves the international standards such as EN, JIS, ASTM, GB, etc.
DX51D
DX51D is a galvanized steel grade designed for cold forming according to the European standard EN 10346. The D, X, 51, and D designations represent hot-rolled steel for various forming processes, strength grades, and general-purpose applications.
DX51D steel is a hot-rolled steel coil for engineering applications with a yield strength of about 235 MPa, which can be tensile or punched.
Other hot rolled grades:
- DX52D
- DX53D
- DX54D
Z275
Z275 refers to the weight of the galvanized layer, i.e. 275 grams of zinc per square meter of double-sided galvanization. Z275 galvanized steel is a highly galvanized steel that can be used in highly corrosive environments such as seacoasts and industrial areas.
Other zinc thicknesses:
- Z80
- Z100
- Z140
- Z150
- Z180
- Z275

DX51D + Z275 Chemical Composition
| Element | Content-Range (%) | Effects and Influences |
|---|---|---|
| Carbon (C) | ≤0.12 | Low carbon content ensures excellent cold formability and weldability. |
| Manganese (Mn) | ≤0.60 | Improves strength and toughness, excessive amounts may affect moldability. |
| Phosphorus (P) | ≤0.10 | Impurity elements, need to be controlled to prevent cold brittleness. |
| Sulfur (S) | ≤0.045 | Impurity elements, and excess will reduce the ductility and weldability. |
| Silicon (Si) | ≤0.50 | Improves strength, excessive amounts may lead to surface defects. |
| Aluminum (Al) | ≥0.015 | Deoxidizer, refine the grain, improve toughness. |
| Other elements | Total ≤0.70 | Including chromium (Cr), nickel (Ni), copper (Cu) and other residual elements. |
dx51d z275 Benefit and Application
DX51D+Z275 galvanized steel is highly coated steel, it has better corrosion resistance, base material ductility, low yield strength + high elongation, and can meet the needs of cold bending, stamping, welding, shearing, etc. in different applications, it is a high-quality coated metal material for construction and industrial production.
| Application Scenarios | Advantages |
|---|---|
| Building Roofing | Wind Pressure Resistance, Corrosion Resistance |
| Automotive Structural Components | Formability, Weldability |
| Home Appliance Panels | Surface Quality, Molding Accuracy |
