Shackles are essential components widely used in marine, construction, lifting, and rigging industries. They serve as removable links to connect chains, ropes, and lifting slings, ensuring secure and safe load handling. Italy, known for its advanced manufacturing and engineering capabilities, hosts several top shackle manufacturers and suppliers that cater to both domestic and international markets. This article explores the leading shackle manufacturers and suppliers in Italy, their products, manufacturing processes, and what makes them stand out in the global marketplace.
Shackles come in various types such as anchor shackles, bow shackles, D-shackles, and chain shackles. They are typically made from high-strength alloy steel or stainless steel to withstand heavy loads and harsh environments, especially in marine applications. The quality of shackles directly impacts safety and efficiency in lifting and rigging operations.
Italy's shackle manufacturers combine traditional craftsmanship with modern technology to produce high-quality shackles that meet international standards. These companies often provide OEM services to global brands, ensuring customized solutions for marine, industrial, and civil applications.

Kong S.p.A is a leading Italian manufacturer known for producing high-resistance heart-shaped shackles with bolt pins. Their products comply with European safety directives and are widely used in adventure parks and safety lifelines. The unique design ensures safety by preventing accidental disconnection during use, making them ideal for recreational and industrial safety applications.
Dawson Group supplies Italy Type drop forged dee shackles, known for their robustness and reliability. These shackles are manufactured through advanced forging processes to ensure high tensile strength and durability, suitable for marine and industrial rigging applications.
The production of high-quality shackles involves several precise steps to ensure durability, strength, and safety:
1. Cutting: Raw round steel is cold-cut into pieces twice the length of the shackle body.
2. Heating and Roll Forging: The steel is heated and hammered into shape to refine grain structure.
3. Punch Bending and Die Forging: These steps form the shackle's body and pin with compact and strong metal structures.
4. Heat Treatment (Quenched & Tempered): Enhances fatigue resistance, allowing the shackle to bend before breaking, ensuring safety.
5. Edge Cutting and Burr Removing: Smoothens surfaces for finishing.
6. Drilling, Tapping, Thread Rolling: Prepares the pin and body for assembly.
7. Surface Treatment: Includes galvanizing, powder coating, or zinc plating to protect against corrosion.
8. Inspection and Packing: Final quality checks before shipment.
This meticulous process ensures that shackles meet stringent international safety and performance standards.
Italian manufacturers emphasize the use of high-grade materials to guarantee performance and durability. Common materials include:
- Alloy Steel: Offers high strength and toughness, suitable for heavy-duty lifting and rigging.
- Stainless Steel (316 Grade): Provides excellent corrosion resistance, especially for marine and offshore applications.
- Carbon Steel: Often used for general-purpose shackles, especially when combined with protective coatings like galvanizing.
The choice of material depends on the application environment, load requirements, and safety standards.
Given the harsh environments in which shackles operate, especially in marine settings, surface treatment is crucial. Italian manufacturers employ several methods:
- Hot-Dip Galvanizing: Provides a thick zinc coating that protects steel from corrosion.
- Powder Coating: Offers a durable and aesthetically pleasing finish that resists chipping and corrosion.
- Zinc Plating: A thinner protective layer for moderate corrosion resistance.
- Electropolishing (for stainless steel): Enhances corrosion resistance and surface smoothness.
These treatments extend the service life of shackles and reduce maintenance costs.
Shackles manufactured in Italy serve a variety of sectors:
- Marine Industry: Used extensively in anchoring systems, mooring, and lifting heavy marine equipment. Marine shackles are often made from 316 stainless steel for corrosion resistance in saline environments.
- Construction and Industrial Lifting: Shackles connect lifting slings and chains for hoisting heavy machinery and materials.
- Adventure Parks and Safety Systems: Specialized shackles like those from Kong S.p.A ensure safety in recreational activities.
- Offshore Oil and Gas: High-strength shackles are critical for securing loads and equipment in offshore platforms.
- OEM Services: Italian manufacturers provide customized shackles and rigging components for global brands, including marine and civil engineering products.
Italian shackle manufacturers adhere to strict quality standards to ensure safety and reliability. Common certifications and standards include:
- EN 13889: European standard for forged steel shackles.
- ISO 9001: Quality management systems certification.
- CE Marking: Compliance with European health, safety, and environmental protection legislation.
- DNV GL Certification: For marine and offshore applications, ensuring materials and products meet rigorous industry requirements.
These certifications assure customers of consistent quality and compliance with international regulations.
Italian manufacturers continuously invest in research and development to improve shackle performance and safety. Innovations include:
- Fatigue-Resistant Designs: Enhanced forging and heat treatment processes increase the fatigue life of shackles, reducing the risk of failure under cyclic loads.
- Smart Shackles: Integration of sensors to monitor load, stress, and wear in real-time, improving safety and maintenance scheduling.
- Lightweight Alloys: Development of shackles using advanced alloys that reduce weight without compromising strength, beneficial for aerospace and specialized marine applications.
