DC07+ZE Electrolytically zinc coated steel
What is DC07+ZE Electrolytically zinc coated steel?
DC07+ZE Electrolytically zinc coated steel has become a preferred material in high-precision manufacturing due to its exceptional formability, uniform coating, and outstanding corrosion resistance. As a specialized grade of cold-rolled steel with an electrolytic zinc coating, DC07+ZE combines the advantages of deep-drawing properties with enhanced surface durability, making it ideal for industries requiring complexity in shaping along with surface protection. With the growing global demand for lightweight parts and longer-life components, this material is increasingly recognized across automotive, home appliance, electrical, and precision stamping sectors.

FAQ
1. Is DC07 hot-rolled or cold-rolled steel?
DC07 is cold-rolled steel. The cold-rolling process is carried out at room temperature, below the recrystallization temperature of the steel, to obtain a smoother surface and more precise dimensional tolerances.
2. Is DC07 steel easy to weld?
Yes, DC07 steel generally has good weldability and can be welded using conventional welding processes.
3. What is the surface finish of DC07?
The cold-rolling process gives DC07 a smoother and more textured surface finish than hot-rolled steel; the surface usually feels oily to the touch.
4. Can DC07 steel be customized in thickness and width?
Yes. The thickness range of DC07 is typically around 0.3 mm to 3.9 mm, and the width is usually between 600 mm and 2000 mm. Specific dimensions can be customized according to customer requirements.
