Import Anchor Chain — Buy in Bulk from Supplier in China

Anchor chains from Sunford Qingdao Industry are manufactured as Proof Coil Chain G30 and High Test Chain G43, conforming to U.S. Type ASTM standards for marine and industrial use. The chains meet rigorous strength requirements, with G30 offering a proof load of 30 ksi and G43 providing 43 ksi for heavier applications. Both grades are built from carbon steel, delivering consistent tensile strength and resistance to dynamic loads typical in vessel anchoring and heavy equipment securing.

The material composition is standard carbon steel, often with manganese additions to improve toughness, while the surface is left uncoated for applications where bare metal is preferred. G30 is typical for smaller vessels and general mooring, while G43 suits larger ships and high-load scenarios. Industry standard lengths per shot are 27.5 m to 90 m, with common diameters ranging from 12 mm to 120 mm depending on the chain’s intended service. Links are typically proof-tested to 1.33 times the working load limit to ensure safety margins.

These chains are used primarily in marine industries for securing boats, ships, and offshore platforms, as well as in construction for lifting and anchoring heavy materials. Importers commonly source these for fishing fleets, cargo vessels, and industrial projects requiring reliable load-bearing equipment. Trade terms such as FOB Qingdao and CIF are typical, with packaging in wooden crates or steel drums to prevent damage during transit. Buyers should confirm the exact grade, diameter, and length required for their application to match the chain’s capacity to the load.

Sunford Qingdao Industry operates from Wuxia Road in Qingdao, Shandong Province, China, with a focus on marine equipment supply. The company’s profile indicates it serves imported markets, with a harbor-tier trust classification, though its response rate and average response time are currently unrecorded. This suggests a supplier oriented toward bulk and international trade rather than rapid small-scale inquiries.

The supplier’s listing highlights anchor chains as a core product, emphasizing compliance with ASTM standards and the provision of both Proof Coil and High Test grades. No additional details such as founding year, certifications, or client history are provided in the available data, so these should be confirmed directly with Sunford Qingdao Industry for a complete assessment of their capabilities and reliability.
