DC07+ZE Cold-rolled Sheet Steel
What makes DC07+ZE unique?
DC07+ZE belongs to the low-carbon cold-rolled steel category, engineered specifically for very deep drawing and intricate forming operations. The electrolytic galvanizing process deposits a fine, tightly adherent zinc layer on the steel surface, providing consistent thickness, outstanding paint adhesion, and high resistance to oxidation and atmospheric corrosion.
Compared with traditional cold-rolled steel grades such as SPCC, SPCD, and SPCE, DC07+ZE offers a much lower yield strength and greater elongation, making it suitable for demanding forming processes where dimensional accuracy and surface smoothness are critical. For manufacturers dealing with extremely complex stamping designs, DC07+ZE is a stronger solution than SPCC (commercial quality) and even more formable than DC04 and DC05 in applications requiring deep-draw reliability.
Performance advantages
The material's core strength lies in the combination of deep-drawing capability and surface protection. Key benefits include:
Excellent formability - enables complicated bending, deep-drawing, and multi-step forming without the risk of cracking.
Superior corrosion resistance - the electrolytic zinc coating provides uniform protection and enhances part lifespan.
Ideal surface quality - extremely smooth and aesthetically clean, suitable for direct painting, electroplating, or powder coating.
High dimensional accuracy - consistent thickness and gauge tolerance due to precision cold-rolling processes.
Eco-friendly coating technology - cleaner than traditional immersion galvanizing and optimized for modern green manufacturing.
Main applications
Industries that require both high formability and long-term surface durability are adopting DC07+ZE rapidly. Common application fields include:
| Industry | Example Components |
|---|---|
| Automotive manufacturing | Door inner panels, fuel tank components, dashboard brackets, trim panels |
| Home appliances | Washing machine drums, outer casings, refrigerator panels |
| Electrical equipment | Distribution cabinet shells, switch boxes, precision stamped parts |
| Industrial forming | Deep-drawn housings, ventilation components, small containers and shells |
Why electrolytically zinc coated steel is gaining market popularity
With rising competitiveness in automotive and appliance manufacturing, companies aim to minimize production defects and material waste. DC07+ZE supports:
Stable stamping efficiency
Lower defect rates in painting and coating
Reduced welding difficulties compared with hot-dip galvanized materials
Due to these advantages, DC07+ZE is not only a cost-effective solution but also one that helps manufacturers meet modern expectations for durability, appearance, energy efficiency, and sustainability.
Application scenarios for other cold-rolled steel grades：
| DC01 can be used for simple forming work, for example Bending, embossing, beading and pulling. |
| DC03 is suitable for forming requirements like Deep drawing and difficult profiles suitable. |
| DC04 is suitable for high deformation requirements. |
| DC05 is a thermal forming grade, it is suitable for higher forming requirements. |
| DC06 is a grade for special deep drawing, suitable for the higher deformation requirements. |
| DC07, this superior deep drawing quality is suitable for highest deformation requirements. |
