DX51D +AZ150, Aluzinc/Galvalume +AZ150, high-coating corrosion-resistant metal material, one of Wanzhi Group’s flagship products. It is a steel material with a cold-rolled steel substrate surface coated with a 55% aluminum (Al), 43.4% zinc (Zn), and 1.6% silicon (Si) alloy coating through a hot-dip galvanizing process. It is typically sold in coil, sheet, or strip form and can undergo further processing such as bending, stamping, and painting.
DX51D +AZ150 Equivalent Grade
| Standard System | Equivalent Grade | Description |
| European Standard (EN 10346) | DX51D+AZ150 | Original standard grade |
| American Standard (ASTM A792/A792M) | AZ50 (Class 1 or 3) | The number after AZ in the U.S. standard represents the coating weight per side (oz/ft²). AZ50 is approximately equivalent to AZ150 (g/m²). |
| Internationally Recognized | Galvalume® | “Galvalume AZ150” is a widely recognized name. |

Solutions
The perfect combination of a 55% aluminum-zinc alloy coating and a high-formability substrate in DX51D+AZ150 galvanized steel provides the optimal solution for corrosion resistance, durability, economy, and functionality in construction and industrial applications. It is one of the comprehensive solutions for high-performance steel.
Building Envelope System Solutions
- Challenge: Roofs and walls must withstand exposure to sunlight, rain, wind, snow, industrial atmospheric corrosion, and regulate indoor temperatures.
- Solution: Utilize AZ150 cold-formed into high-strength arched corrugated panels or standing seam roof/wall systems. Surfaces can be coated with SMP (silicon-modified polyester) or HDP (high-durability polyester) coatings.
- Core Advantages: High strength and cost-effective, resistant to acid rain and UV erosion, up to 80% heat reflectivity, wind pressure resistance, and snow load resistance.
Appliance Manufacturing Solutions
- Challenge: Components must operate in high-temperature, high-humidity environments while maintaining good formability and aesthetic appeal.
- Solution: Critical components with high heat resistance and corrosion resistance requirements use AZ150 galvalume steel as raw material.
- Core Advantages: Aesthetically pleasing and clean, high production efficiency, resistant to high-temperature and high-humidity corrosion.
Transportation Solutions
- Challenge: Requires lightweight design for energy efficiency, while being resistant to water and other chemical corrosion, and capable of withstanding high temperatures.
- Solution: AZ150 is used to manufacture non-load-bearing structural components and insulation parts.
- Core Advantages: Excellent heat resistance capable of withstanding high temperatures, lightweight and high-strength, weather-resistant and corrosion-resistant.
Agricultural Storage Solutions
- Challenge: The internal environment of warehouses is humid, producing highly corrosive gases that severely corrode steel.
- Solution: 0.8mm-1.2mm AZ150 galvalume sheets as construction materials.
- Core Advantages: Robust structure and extreme corrosion resistance, virtually maintenance-free throughout the service life, and cost advantages.
