Products Description
4-inch galvanized steel pipes are made through a strict cold rolling and electric resistance welding (ERW) process, followed by a hot-dip galvanizing treatment. This creates a metallurgically bonded zinc coating that provides sacrificial protection to the steel underneath, significantly extending the service life even in harsh environments.

Products Advantages
Long-Lasting Corrosion Resistance: The hot-dip galvanizing offers superior protection compared to electroplating, ideal for outdoor and humid conditions.
High Pressure Resistance: Robust wall thickness allows these pipes to handle high internal pressure in fluid transportation.
Excellent Durability: The zinc coating is tough and abrasion-resistant, preventing damage during transport and installation.
Ease of Fabrication: Can be easily cut, welded, threaded, and bent (with appropriate tools) on site.
Cost-Effective Solution: Provides a great balance of performance and cost, reducing long-term maintenance and replacement expenses.
Products Applications
Potable Water Systems: Underground and above-ground water supply lines.
Construction Scaffolding: As vertical standards and ledger pipes for support structures.
Security Fencing: For high-strength perimeter fencing, farm fencing, and highway guardrails.
