Galvanized Sheet
DX51D Z150 Galvanized Sheet is a premium hot-dip galvanized steel product widely used in construction, manufacturing, and infrastructure projects. The DX51D base steel defined under EN 10346 offers excellent cold-forming capability, while the Z150 zinc coating provides durable corrosion protection, making this material an optimal solution for long-term service in demanding environments.
Galvanized sheet is a type of steel that is coated with zinc for protection by an electroplating process. The galvanized layer is applied to cold rolled steel at low temperatures. Zinc is generally represented by Z. Z is the abbreviation of English Zinc. For example, the Z80 surface zinc plating content is 80 grams per square. Z150 means that the galvanizing content is 150 grams per square meter, and so on. The number after Z indicates the average coating content at three points on both sides of the galvanized steel in grams per square meter. The general materials of hot-dip galvanizing on the market are: Z80, Z100, Z120, Z140, Z180, Z275, etc.
What Is DX51D Z150 Galvanized Sheet?
| Item | Description |
|---|---|
| Steel grade | DX51D |
| Standard | EN 10346 |
| Product form | Galvanized steel sheet |
| Zinc coating | Z150 (150 g/m² both sides) |
| Processing | Hot-dip galvanized |
The Z150 designation indicates a total zinc coating mass of 150 g/m², which significantly improves corrosion resistance compared with lighter coatings such as Z60 or Z100.
Chemical Composition of DX51D Base Steel
| Element | Max Content (%) |
|---|---|
| C | 0.12 |
| Mn | 0.60 |
| P | 0.10 |
| S | 0.045 |
| Al | ≥ 0.015 |
This controlled low-carbon composition ensures excellent formability and stable surface quality after galvanizing.

FAQ:
1. What coating types are available for DX51D galvanized steel?
Answer: The most common coating is hot-dip galvanized (GI). Zinc coating weight ranges from Z60 to Z275 g/m², depending on corrosion protection needs.
2. Which international standards cover DX51D?
Answer: DX51D is produced according to EN 10346, and it is comparable to ASTM A653 CS Type B and JIS G3302 SGCC.
3. Is DX51D suitable for forming and stamping?
Answer: Yes. DX51D offers excellent bending, stamping, roll forming, and welding performance, making it ideal for deep processing and fabrication.
4. How can the zinc coating thickness be checked?
Answer: Coating thickness can be measured using magnetic thickness gauges or X-ray equipment, and verified through coating weight markings such as Z100, Z180, or Z275.
5. What surface finishes are available for DX51D galvanized steel?
Answer: Available surface finishes include regular spangle, minimized spangle, zero spangle, oiled, dry, chromated, and anti-fingerprint.
