High-Quality SECC /SECD/SECE 20/20 coating Electro-galvanized steel plate Suppliers, Factories

electro-galvanization employs an electric current to deposit dissolved zinc onto the surface of the material to be plated. This method offers uniform coating thickness and decorative properties, making it a preferred choice for various applications. However, unlike hot-dip galvanization, electro-galvanized materials typically undergo chromate treatment to enhance corrosion resistance and prevent white powdery corrosion formation.

The Electroplating Production Process

Below is a detailed description of the important steps in the electroplating process:

1. Surface Preparation and Pretreatment

The surface of the steel sheet must be perfectly prepared before electroplating. This ensures that the electroplated layer can firmly and evenly adhere to the metal surface.

  • Surface Cleaning: Thoroughly clean to remove impurities, dust, and grease.
  • Surface Pretreatment: Utilizing methods like sandblasting, abrasion, or chemical cleaning to create a uniform surface.
2. Electroplating Process

This process takes place in a container with an electroplating solution:

  • Pre-treatment: Immersion in an alkaline solution to increase conductivity.
  • Zinc Electroplating: Current passes through the solution, depositing zinc ions onto the surface.
  • Adjusting the Layer: Controlling current and contact time to regulate thickness.
Applications of Electroplated Steel
Construction Industry

Favored for manufacturing roofing sheets, water pipes, drainage pipes, and ventilation systems. It shields and protects metal components, enhancing lifespan against weather impact.

Automotive & Motorcycle

Used for exterior parts and components. The zinc layer protects vehicle frames from water, dust, and pollutants while maintaining aesthetic beauty and durability.

Consumer Goods

Applied in electronics for screws and circuits, and in household items like pots, pans, and dishes to provide a shiny, corrosion-resistant finish.

Daily Life

Utilized in decorative items, advertising signs, and interior furnishings, as well as specialized equipment in agriculture and the oil industry.

Fastening Solutions: Coiled Nails
  • High Capacity: Allows for extended use without frequent reloading, improving productivity.
