Customized galvanized stainless steel ball joints - forged hardware
for power line insulators
Product Overview
Our customized galvanized stainless steel ball joints are
precision-engineered forged hardware components designed for power
line insulator systems. Manufactured with high-grade stainless
steel and hot-dip galvanized for superior corrosion resistance,
these ball joints ensure long-term durability, high mechanical
strength, and reliable performance in harsh outdoor environments.
Key Features & Benefits
✔ Premium Stainless Steel Construction – Made from 304/316
stainless steel for excellent corrosion resistance and structural
integrity.
✔ Hot-Dip Galvanized Finish – Provides extra protection against
rust, UV exposure, and extreme weather conditions.
✔ Precision Forging & CNC Machining – Ensures tight tolerances
(±0.1mm), smooth articulation, and optimal load distribution.
✔ High Load-Bearing Capacity – Supports heavy mechanical stress in
power transmission and distribution systems.
✔ Customizable Designs – Available in various sizes, thread types
(metric/SAE), and configurations to fit specific insulator hardware
requirements.
✔ Low Maintenance & Long Service Life – Ideal for utility poles,
transmission towers, and substation hardware.
