1. High Strength Starts from Material Selection and Forging Process

A lifting shackle needs to withstand not only static loads but also impact forces and repeated loading during daily operations.

Using unsuitable materials or improper manufacturing processes may result in:

• Reduced load performance

• Deformation under heavy loads

• Shorter service life

To improve product reliability, Haosail uses qualified materials combined with professional forging technology.

With our own manufacturing capabilities, including multiple forging production lines and advanced testing equipment, we are able to maintain stable product quality and mechanical performance.

The forging process helps improve:

✔ Material strength
✔ Structural integrity
✔ Resistance against deformation

2. Improving Corrosion Resistance Through Surface Treatment Technology

For shackles used in marine, offshore and outdoor environments, corrosion is one of the biggest challenges.

Corrosion may affect:

• Surface appearance

• Pin operation

• Long-term service reliability

Based on years of industry experience, Haosail has continuously optimized shackle surface treatment processes and material applications to improve corrosion resistance.

According to our testing results, the improved shackle showed no rust or surface changes after a 247-hour salt spray test, while some conventional shackles developed corrosion at much earlier stages.

This improvement provides:

✔ Longer service life
✔ Better environmental adaptability
✔ Reduced maintenance requirements

3. Quality Control Throughout the Entire Manufacturing Process

Product reliability is not created by one single process. It requires control from raw materials to finished products.

At Haosail, our quality management system covers:

Raw material inspection → Production process control → Finished product testing → Quality traceability

Through strict quality management, we ensure every batch maintains consistent performance and meets customer requirements.

4. Continuous Innovation to Meet Different Customer Requirements
