Hot-dip galvanized steel
DX54D is a cold-rolled, continuously hot-dip galvanized steel, known for its excellent corrosion resistance and formability. It is perfect for uses that demand both long-lasting performance and visual appeal. Typically used in automotive parts, roofing materials, and home appliances, DX54D offers reliable performance in environments exposed to moisture and harsh conditions. Its high elongation and ability to maintain structural integrity make it suitable for stamping, welding, and other manufacturing processes.
D: Indicates a steel grade designed for deep drawing and formability.
54: Refers to the minimum yield strength of 280 MPa (which is around 54,000 psi) for structural applications.
D: The second "D" signifies that the material is designed for galvanization and is well-suited for corrosion resistance in outdoor or industrial applications.
DX54D Equivalent Grades
DX54D has the following equivalent grades:
EN 10346-2015: 1.0952
EN 10346-2009: 1.0306
DX54D Galvanized Steel Sheet Chemical Composition
| Element | Composition (weight %) |
| Carbon (C) | ≤ 0.12% |
| Silicon (Si) | ≤ 0.5% |
| Manganese (Mn) | ≤ 0.6% |
| Phosphorus (P) | ≤ 0.1% |
| Sulfur (S) | ≤ 0.045% |
| Titanium (Ti) | ≤ 0.3% |
| Upon agreement during inquiry or order, the titanium content in this steel grade can be reduced to < 0.05%, making it a non-alloy steel. | |

Spangle
The "spangle" is a type of surface morphology found on hot-dip galvanized (pure zinc-coated) steel coils. When the steel strip passes through the zinc pot, its surface becomes coated with liquid zinc. As the zinc layer naturally solidifies, zinc grains nucleate and grow, forming what is known as "spangle."
The name "spangle" comes from the fact that the complete zinc crystals display a snowflake-like pattern, which is quite vivid and descriptive.
