Qingdao Haosail Machinery Co., Ltd.

Qingdao Haosail Machinery, a leader in industrial hardware innovation, has once again redefined industry standards with the launch of its next-generation, ultra-corrosion-resistant shackle. By leveraging proprietary surface treatment technologies and advanced materials, the company has not only significantly enhanced the shackle's corrosion resistance but also reinforced its unique capability to deliver tailored solutions that meet specific customer requirements.

The newly developed shackle showcases exceptional performance in rigorous salt spray tests, far surpassing conventional alternatives. While standard shackles showed rust after only 35, 72, and 170 hours, our shackle remained completely rust-free and unaltered after 247 hours. More notably, its screw remained fully operational and could be easily removed-a critical advantage in real applications where conventional shackles often fail due to rust.

With an in-house professional R&D team and decades of engineering experience, the company collaborates directly with clients to develop bespoke solutions based on specific needs-including product appearance, dimensional requirements, material selection, and performance criteria.

Whether they operate in marine, construction, or specialized industrial sectors, we can design and produce shackles that meet exact application demands-from enhanced corrosion protection to unique sizes or mechanical properties.This combination of proven product excellence and flexible customization offers clients not only longer service life and reduced maintenance costs, but also a trusted partnership for unique lifting and securing challenges.
