Key Performance Features
- Precision Drop-Forging: Eliminates internal porosity and structural defects, providing high fatigue resistance against dynamic wind loads.
- Smooth Contour Design: Smoothly rounded body and pin holes minimize mechanical stress concentration and prevent excessive wear on connected hardware.
- Long-Term Anti-Corrosion: Heavy zinc coating protects against humidity, industrial pollution, and coastal salt spray environments.
Quality Assurance
Every batch of U-shackles manufactured by YiHao Power undergoes strict quality control, including non-destructive flaw testing, dimensional checks, and zinc coating thickness inspection.
