Products Description
DX53D+ZM Galvanized Steel Coil is a high-grade, hot-dip galvanized low-carbon steel product engineered for exceptional deep drawability, superior corrosion resistance, and flawless surface quality. As a core offering from GNEE STEEL, this coil integrates a pure zinc coating with specialized passivation (+ZM), ensuring optimal performance in complex forming operations and harsh environments. Ideal for automotive, home appliance, construction, and industrial applications, DX53D+ZM delivers unmatched ductility, consistency, and cost-effectiveness.
Key Product Advantages
Unmatched Deep Drawability: DX53D (Deep Drawing Grade) offers higher elongation and r-value than DX51D/DX52D, enabling crack-free forming of intricate, multi-stage stamped components.
Enhanced Corrosion Protection: The +ZM passivated zinc coating provides superior resistance to white rust and atmospheric corrosion, extending service life in humid or coastal conditions.
Flawless Surface Finish: Available in zero/spangle options with anti-fingerprint treatment, ensuring smooth aesthetics and excellent paint adhesion for exposed parts.
Strict Dimensional Precision: Tight tolerances for thickness (±0.01mm) and width (±2mm) guarantee consistency in high-volume production.
Reliable Quality Compliance: Manufactured to EN 10346, ASTM A653, and ISO standards, with full mill test certification for every batch.

Frequently Asked Questions (FAQ)
1. What does DX53D+ZM mean?
DX53D denotes a deep drawing grade of hot-dip galvanized steel; +ZM indicates a zinc coating with passivation for enhanced corrosion resistance during storage.
2. How is DX53D+ZM different from DX53D+Z?
DX53D+Z is standard galvanized steel, while +ZM includes additional passivation to reduce white rust formation, making it ideal for long-term storage or humid environments.
3. What coating weights are available?
Standard options range from Z50 to Z275 g/m², with Z140 and Z200 being the most common for balanced protection and cost.
4. Can you provide custom dimensions?
Yes. We offer customized thickness, width, coil ID, and weight to meet specific production needs.
5. What surface finishes are offered?
Options include regular spangle, mini spangle, zero spangle, anti-fingerprint, and chromated finishes.
6. Is DX53D+ZM suitable for welding?
Absolutely. It exhibits excellent weldability for resistance, arc, and laser welding, supporting efficient assembly.
7. What certifications do you provide?
Each batch includes a Mill Test Certificate (MTC) verifying compliance with EN 10346, ASTM A653, and ISO 9001.
8. What is the typical lead time?
Standard orders ship within 15–20 days; urgent orders can be expedited. Contact us for precise scheduling.
