Galvanized steel plate
DX51D galvanized steel plate is a hot-dip galvanized product made from low-carbon steel, featuring a uniform zinc coating that provides excellent rust resistance. It's widely used in construction due to its high formability, making it easy to cut, bend, and weld into various shapes. Unlike other grades, DX51D balances cost-effectiveness and performance, making it the top choice for residential, commercial, and industrial building projects.
Chemical Composition of GNEE's DX51D Galvanized Steel Plate
The precise chemical makeup of our DX51D plates ensures consistent performance and compliance with international standards (EN 10346, ASTM A653).
| Element | Content (%) | Function |
|---|---|---|
| Carbon (C) | ≤0.12 | Ensures formability for construction processing |
| Silicon (Si) | ≤0.05 | Improves welding performance |
| Manganese (Mn) | ≤0.60 | Enhances tensile strength |
| Phosphorus (P) | ≤0.045 | Controls brittleness |
| Sulfur (S) | ≤0.045 | Reduces internal defects |
| Aluminum (Al) | ≥0.020 | Improves zinc coating adhesion |
