SuperDyma™ is a new type of highly corrosion-resistant coated steel sheet with a coating composition consisting of zinc as the main substrate in combination with aluminum (about 11%), magnesium (about 3%) and a trace amount of silicon.
SuperDyma is a special coated steel from Nippon Steel & Sumitomo Metal (NSSMC).
Now, Hengze Steel had cooperated with the lagest Distributor of NSSMC in China. We can supply highly corrosion-resistant Zinc-Aluminum-Magnesium Coated Steel as your need.
- Corrosion resistance
SuperDyma has superior durability, especially the corrosion resistance is superior 10-20 times than Galvanized steel and 5-8 times than Galvalume steel.
- Wear resistance
Coating layer of SuperDyma is harder than ordinary Galvanized steel, so SuperDyma have good durability for wear and scratch.
SuperDyma has good corrosion resistance at not only flat point but cut edge in heavy corrosive environment, so total cost reduction is available by process omission of anticorrosion treatment, for example, post hot dip zinc coating, post electrolytic zinc coating and several chromate treatments, and post painting for hot rolled and cold rolled steel. Of course it is available for the parts that need superior corrosion resistance than ordinary Galvanized steel.

SuperDyma™ vs ZAM®
SuperDyma™ and ZAM® have almost similar advantages.
Coating layer of ZAM® has minute cell structure consist of Zn-6%Aluminum-3%Magnesium alloy, and the corrosive growth is very stable. And the layer of SuperDyma™ consist of Zn-11%Aluminum-3%Magnesium alloy.
