Electro Galvanized Wire

Product Introduction

Electro-galvanized wire, also known as cold galvanized wire, is made from high-quality carbon steel wire. The processing of this wire involves galvanizing using electrolytic equipment. Generally, the galvanized layer is not very thick, but electro-galvanized wire has sufficient corrosion and oxidation resistance. Additionally, the surface of the galvanized layer is very uniform, smooth, and bright. The zinc coating weight of electro-galvanized wire typically ranges from 8 to 50 grams per square meter. This type of wire is primarily used for manufacturing nails, wire ropes, wire mesh, fences, floral binding, and wire weaving.

The difference between Electro Galvanized Wire and Hot Dipped Galvanzied Wire

Definition and Process

Hot Dipped Galvanized Wire: Produced by immersing steel parts in a molten zinc solution (about 500°C). The zinc forms a protective layer on the steel to prevent corrosion. This process is widely used in structural metal facilities across various industries.

Electro Galvanized Wire: Created through electroplating, where a thin layer of zinc is deposited on steel using electrolytic processes. This process provides corrosion resistance but is less durable compared to hot-dip galvanizing, often used for decorative and light corrosion protection.

Process Flow

Hot Dipped Galvanized Wire:

Steps: Pickling → Washing → Booster Solution → Drying → Plating → Cooling → Cleaning → Polishing → Hot-Dip Galvanizing.

Electro Galvanized Wire:

Steps: Degreasing → Washing → Electrolytic Plating → Passivation → Drying.

Processing Techniques

Hot Dipped Galvanized Wire: The workpiece is immersed in molten zinc for a specific duration to create a thick, durable coating. It's commonly used for heavy-duty applications like pipe fittings.

Electro Galvanized Wire: Utilizes electroplating equipment to deposit a thin, uniform zinc layer onto the steel surface. The process is typically less complex and used for lighter applications.

Appearance

Hot Dipped Galvanized Wire: The surface is typically rough and may show signs of process water lines or zinc buildup, especially at the ends. The finish is a silvery-white color.

Electro Galvanized Wire: The surface is smooth with a uniform appearance. It typically has a yellow-green or bluish tint, with no visible zinc buildup or defects
