Key Benefits

The electrogalvanizing process ensures high-quality finishes:

  • Superior Corrosion Resistance
  • Significantly Extended Service Life
  • Enhanced Aesthetic Quality
⚙️ Electrogalvanizing Process

Corrosion Protection Mechanism: Zinc's oxidation resistance protects steel in both dry and humid environments. If damaged, a zinc-steel galvanic couple sacrificially protects the substrate.

Standard Process Flow:

  1. Surface Preparation: Alkaline degreasing → Hot water rinse → Acid pickling → Rinsing
  2. Electroplating: Zinc electrodeposition → Rinsing
  3. Post-treatment: Chromate passivation → Hot water rinse → Drying
  4. Quality Assurance: Inspection → Packaging

❓ Frequently Asked Questions
What is the standard for these electro-galvanized materials?
All materials are produced according to the Q/BQB430-2009 manufacturing standard.
What are the available thickness and width ranges?
The thickness ranges from 0.3mm to 3.5mm, and the width ranges from 800mm to 1830mm.
Which grade should I choose for deep drawing applications?
For deep drawing, SECE, DC04E+Z, or BUSDE+Z are recommended. For special extra deep drawing, DC07E+Z is suitable.
How does the zinc coating protect the steel substrate?
The zinc layer provides oxidation resistance. In case of surface damage, it acts as a sacrificial anode in a galvanic couple to protect the underlying steel.
What is the maximum zinc coating weight available?
The products support a maximum zinc coating of 90/90 g/m2.
What are the common post-treatment steps?
Standard post-treatment includes chromate passivation, hot water rinsing, and professional drying to ensure surface stability.
