What is DX52D+ZM Steel?
DX52D+ZM steel is a high-formability cold-rolled steel grade coated with a zinc-aluminum-magnesium (Zn-Al-Mg) alloy coating, produced in accordance with EN 10346 standard. It is designed for applications requiring both excellent forming performance and superior corrosion resistance, especially in outdoor and structural environments.
DX52D+ZM = Cold-forming steel with Zn-Al-Mg coating
DX52D: Base steel grade for deep drawing and high formability applications
+ZM: Zinc-Aluminum-Magnesium (Zn-Al-Mg) metallic coating
Standard: EN 10346

Coating Performance Laboratory Test (Zn-Al-Mg vs GI)
1. Neutral Salt Spray Test (NSS)
This test compares the cutting-edge corrosion resistance of GI sheet and Zinc-Al-Mg coated steel.
The results show that Zn-Al-Mg steel achieves significantly longer red rust resistance time, reaching up to 3300 hours, which is approximately 20 times higher than conventional galvanized steel under the same conditions.
Neutral Salt Spray Test (NSS)
2. Cyclic Corrosion Test (CCT)
The CCT results further confirm the superior long-term durability of Zinc-Al-Mg coating.
Compared with GI coil, Zn-Al-Mg coated steel maintains a much cleaner surface condition after extended exposure cycles (240h / 624h / 960h), showing slower corrosion development and better surface stability.
Cyclic Corrosion Test (CCT)
These laboratory tests clearly demonstrate that Zn-Al-Mg coated steel provides significantly higher corrosion resistance and longer service life than conventional GI steel, making it ideal for outdoor structural applications such as solar mounting systems.
