DC52D+AZ50 AZ100 AZ150 Galvalume Steel Sheet

When your project demands both extreme formability and long-term atmospheric protection, DC52D+AZ Galvalume Steel Sheet stands as the industry's premier solution. Combining the superior deep-drawing properties of the DC52D substrate with the high-performance 55% Aluminum-Zinc alloy coating, this material is engineered for complex architectural shapes and demanding industrial components.

At GNEE STEEL, we specialize in providing DC52D+AZ sheets with precise coating weights ranging from AZ50 to AZ150, ensuring that whether you are manufacturing intricate automotive parts or durable roofing systems, you have the exact level of protection required.

What Is DC52D Galvalume Steel Sheet?

 

The "DC52D" designation signifies a Deep Drawing Quality steel, which offers higher ductility than standard commercial grades (like DC51D). The "+AZ" indicates the hot-dip Al-Zn coating, which is categorized by its mass per square meter.DC52D+AZ galvanized sheet is a type of galvanized material with excellent performance, widely used in multiple fields

The number following "AZ" represents the total coating weight on both surfaces (grams per square meter). Choosing the right weight is critical for balancing cost and service life:

AZ50 (50 g/m^2): Optimized for indoor applications or mild environments where cost-efficiency is a priority. It offers excellent weldability and surface smoothness.

AZ100 (100 g/m^2): The standard "workhorse" for general construction and outdoor cladding. It provides a robust balance of barrier protection and sacrificial protection.

AZ150 (150 g/m^2): Designed for heavy industrial or coastal environments. This thick coating ensures maximum longevity against salt spray and high humidity.

To help you select the ideal material for your manufacturing process, refer to the professional data table below:

• Extreme Formability: DC52D allows for complex bending and deep drawing without the coating cracking or the base metal fracturing.
• Heat Reflectivity: The 55% Aluminum content reflects over 65% of solar energy, significantly reducing cooling costs in building structures.
• Self-Healing Properties: The Zinc component in the AZ coating provides sacrificial protection at cut edges and scratches, preventing "red rust" creep.
• High-Temperature Stability: Our Galvalume sheets maintain their integrity and surface finish at continuous temperatures up to 315°C.

1. What is the difference between DC51D and DC52D?

DC51D is for general commercial use and simple bending, while DC52D is specifically designed for deep drawing, offering better elongation and ductility for complex shapes.

2. Can DC52D+AZ150 be used in highly corrosive environments?

Yes. The AZ150 coating provides the highest level of protection available for Galvalume, making it suitable for industrial zones and areas near the ocean.

3. Does the AZ coating affect the painting process?

Not at all. In fact, DC52D+AZ is an ideal substrate for color coating (PPGL). Its surface provides excellent paint adhesion.

4. How does Galvalume compare to traditional Galvanized (GI) steel?

Galvalume (AZ) typically lasts 3 to 6 times longer than Galvanized (Z) steel of the same coating thickness due to the aluminum barrier protection.

5. What surface treatments does GNEE STEEL offer?

We offer various treatments including Chromated (Cr6+ or Cr3+), Oiled, Anti-fingerprint (AFP), or Dry, depending on your storage and processing needs.

6. Is there a minimum order quantity (MOQ)?

We support both large-scale infrastructure projects and smaller specialized manufacturing runs. Please contact our team for specific MOQ details based on your size requirements.

7. Does the coating flake off during deep drawing?

When using DC52D grade, the coating is engineered to adhere tightly to the steel. Provided the correct lubrication and tooling are used, the AZ coating will remain intact during the drawing process.

8. What is the typical lead time for an order?

For standard specifications of DC52D+AZ50/100/150, our lead times are highly competitive. Custom widths and thicknesses usually ship within 15–30 days.
