Australia's marine and offshore industries demand high-quality, reliable anchor chains and shackles to ensure vessel safety and operational efficiency. From recreational boating to large-scale offshore platforms, anchor chains and shackles play an essential role in securing vessels against the forces of nature. This article explores the top anchor chains manufacturers and suppliers in Australia, emphasizing their product offerings, manufacturing processes, certifications, and the critical role of anchor shackles within the marine hardware sector.
Anchor chains are vital components in maritime mooring systems. They link the vessel to the anchor and bear the stress from currents, waves, and wind. These chains must offer exceptional strength, fatigue resistance, and corrosion protection, especially in harsh ocean environments. Shackles complement anchor chains by providing strong, flexible connections between chain segments, anchors, and other mooring equipment.
In Australia, manufacturers produce anchor chains and shackles that comply with rigorous standards such as ISO and Australian maritime certifications. Products range from galvanized studlink chains—equipped with crossbars inside each link for added strength—to studless chains that offer greater flexibility. Australian suppliers also provide a wide variety of shackles, including bow shackles, D shackles, and specialty lifting shackles tailored for marine applications.
Established in 1966, Serafini Chains is the largest chain manufacturer in Australia and the sole domestic producer in Queensland. Their state-of-the-art facility manufactures welded steel chains and lifting gear ranging from 3mm to 150mm diameter, catering to marine, agricultural, and industrial applications. Serafini Chains holds ISO9001 certification, ensuring that their products meet international quality standards.
Their products are renowned for durability and compliance with safety standards, serving clients across Australia and exporting globally. Their expertise in chain metallurgy, welding, and finishing processes significantly enhances chain strength and fatigue life.
Franklin Offshore specializes in supplying rigging, mooring, and lifting equipment to offshore and marine industries. Their product range includes studlink and studless anchor chains, lifting shackles, synthetic ropes, and anchor winches. Franklin Offshore carefully selects global brands and exacts high standards for rigging gear used in Australia's demanding offshore environment.
Their customer-focused approach, combined with their robust inventory of certified products, makes them a go-to supplier for offshore platforms, commercial vessels, and recreational boaters alike.
- Sam Allen Marine: A Queensland-based supplier providing a wide variety of anchor chains and marine accessories for commercial and leisure boats.
- Baohai Marine & Zhengmao (Chinese Manufacturers): These Chinese manufacturers are represented in Australia by distributors who provide high-quality mooring and anchor chains meeting global marine standards.
- RUD Australia: Known for innovative lifting gear and steel chain products, they offer specialized lifting and anchoring equipment, including bolt-on and weld-on lifting devices.
LiftQuip supplies a broad range of shackles specifically designed for marine, industrial, and construction uses. Their product portfolio includes soft shackles and heavy-duty stainless steel shackles that resist corrosion in saltwater environments. LiftQuip shackles are graded (S, M, and commercial grades) to fit various rigging and mooring requirements, backed by adherence to Australian and international safety standards.
Franklin Offshore is also a major supplier of premium shackles, including Van Beest's Green Pin brand, known for its high strength and reliability. Their offerings include safety pin bow shackles, screw pin shackles, and heavy-duty shackles designed for mooring and lifting. These shackles come with certifications conforming to offshore container and lifting regulations.
Hampidjan Australia provides an extensive range of marine-grade shackles, including Green Pin bow shackles with sunken hole pins. These shackles boast excellent corrosion resistance and strength, assuring safety and longevity in marine applications.
Manufacturing anchor chains involves several precise and controlled steps to ensure performance and safety:
1. Raw Material Preparation: High-grade steel rods like CM490 or CM690 are precisely cut to required lengths.
2. Heating: Steel pieces are heated to high temperatures to allow shaping.
3. Link Formation: Hot steel is shaped into links through hydraulic presses and bending machines, and then welded with arc welding.
4. Heat Treatment: Post-welding, the links undergo heat treatment (quenching and tempering) to improve strength, toughness, and fatigue resistance.
5. Surface Finishing: Chains are galvanized through hot-dip galvanizing or coated to guard against corrosion.
6. Quality Inspection: Every link undergoes strict dimensional, welding, and surface finish inspections to meet standards set by certification bodies such as ABS, DNV, and Lloyd's Register.
Shackles require equally stringent production processes for safety-critical marine use:
- Cutting and Heating: Alloy steel rods are cut and heated for forging.
- Roll Forging and Punch Bending: The hot steel is hammered and shaped to form the shackle body and pin, enhancing the internal grain structure.
- Die Forging: This key step consolidates the metal structure and improves mechanical properties.
- Heat Treatment: Quenching and tempering provide high fatigue resistance while allowing flexibility to prevent brittle fracture.
- Surface Finishing: Burr removal, drilling, thread rolling, and surface treatments such as galvanizing or coating ensure smoothness and corrosion resistance.
- Inspection and Quality Control: Every piece is tested to meet load requirements and certified according to AS 2741 and other relevant standards.
- Studlink Anchor Chains: Equipped with internal studs that prevent chain deformation and enhance tensile strength. Widely used for heavy-duty applications.
- Studless Anchor Chains: Lack studs, providing increased flexibility and reduced weight; ideal for certain marine applications where chain bending is critical.
- Galvanized Chains: Steel chains coated to resist corrosion from saltwater exposure.
- Stainless Steel Chains: Offer superior corrosion resistance, preferred in highly corrosive environments.
- Bow Shackles: Feature an arched shape suitable for multi-directional loading, commonly used in mooring and lifting.
- D Shackles: Have straight sides and are typically used for linear pull applications.
- Screw Pin and Bolt-Type Shackles: Offer different locking mechanisms to fit particular rigging and safety needs.
Anchor shackles are crucial for connecting anchor chains to anchors, mooring lines, and other rigging components. Their quality directly impacts safety at sea, as they bear immense loads and endure constant environmental stress. Reliable Australian manufacturers and suppliers ensure shackles are made from high-grade materials, undergo strict quality controls, and feature protective surface treatments to extend service life in marine conditions.
- Strict Quality Standards: Products comply with Australian and international certifications, ensuring reliability and safety.
- Technological Innovation: Use of advanced steel alloys, automated manufacturing, and digital inspections yield superior performance.
- Customization and OEM Services: Many manufacturers provide OEM options to tailor chains and shackles to specific vessel or industry requirements.
- Local Expertise and Support: Extensive knowledge of local marine conditions results in products optimized for Australian waters.
- Global Shipping Capability: Australian manufacturers export globally, demonstrating the robustness and quality of their products.
