ASTM A36 ​Electrogalvanized Low Carbon Steel Wire

1. Galvanized Wire Product Introduction: 

Galvanized wire, also known as galvanized iron wire, is a type of metal wire made from high-quality low-carbon steel wire rod through a series of processes, including drawing, pickling, annealing, and hot-dip or electroplating. Its surface is coated with a uniform and dense zinc layer, significantly improving its corrosion resistance and service life. It is one of the most common and important metal materials used in daily life and industrial production.

2. Electrogalvanized Wire
Process: High-quality wire rod → Drawing → Annealing (softening treatment) → Pickling (removing oxide scale) → Electrogalvanizing (in an electrolytic bath, an electric current is passed to deposit zinc ions on the wire surface) → Passivation treatment (optional, to enhance rust resistance) → Winding and coiling.
Features: The zinc layer is thin, typically 5-20μm. The surface is smooth, bright, and uniform, with good flexibility. However, its corrosion resistance is inferior to hot-dip galvanizing, making it suitable for use in dry or mildly corrosive environments.

3. Product Features
Excellent Corrosion Resistance: The zinc layer acts as a protective barrier, effectively insulating the iron matrix from air and moisture, preventing rust from forming. Even with minor damage, the zinc layer continues to protect the wire through its "sacrificial anode" cathodic protection.
Long Service Life: Depending on the operating environment, the service life of galvanized wire can be several to dozens of times longer than that of ordinary black iron wire (bright wire).
Good Toughness and Elasticity: Annealed galvanized wire (especially electro-galvanized wire) exhibits excellent flexibility and a certain degree of elasticity, making it easy to bend, weave, and form.
Aesthetic Surface: Electro-galvanized wire has a smooth silvery-white surface; hot-dip galvanized wire has a slightly darker, silver-gray surface with a distinctive galvanized pattern.
High Strength: Products with varying tensile strengths can be produced by controlling the drawing process to meet the needs of different applications.
Cost-Effectiveness: While providing excellent rust protection, the price is more affordable than materials such as stainless steel.

4. Main Applications

Galvanized wire has a wide range of uses, found in nearly all industrial and consumer sectors: construction and bundling, mesh products, daily necessities and hardware, communications and power generation, and other industrial fields.

5. Common packaging methods: plastic inside and woven outside, plastic inside and linen outside.
