What is Galvanized Barbed Wire?
Hot Dipped Galvanized Barbed Wire is a double-strand steel wire twisted with sharp barbs, designed for security fencing, boundary marking, and anti-intrusion protection. GABION-S produces barbed wire using high-purity low-carbon steel and applies hot-dip galvanizing, providing outstanding corrosion resistance even in marine, desert, and high-humidity environments.
Manufacturing Process
Our galvanized barbed wire is manufactured through a controlled process:
- Wire drawing – low-carbon steel wire is drawn to target diameter.
- Hot-dip galvanizing – thick zinc coating ensures long-term outdoor durability.
- Double-strand twisting – two wires twisted to improve tensile performance.
- Barb formation – 2-point or 4-point barbs fixed at equal intervals.
- Roll forming & inspection – each roll is measured, weighed, and tested.
Product Types
Economical option for agricultural and rural fencing.
Suitable for farms, gardens, small enclosures.
Higher tensile strength; widely used for industrial security.
For long-span fencing and harsh environments.
Reduced sagging and longer service life.
Additional polymer coating for enhanced chemical resistance.
Available in green, black, blue.
