Import Double Loop Chain — Buy in Bulk from Supplier in China

The Double Loop Chain from San Yi Chain Hardware Co., Ltd is forged from low carbon steel with a carbon content of 0.15% to 0.25%, as confirmed by material certification in the supplier's documentation. Each link measures 12 mm in diameter with a standard pitch of 45 mm, and the chain is available in lengths from 1 meter to 10 meters in 0.5-meter increments. The surface is untreated, leaving the natural mill finish visible, which allows for easy coating or painting if required for corrosion protection.

This chain is typically used in industrial lifting and load-securing applications where moderate tensile strength and flexibility are required. The double-loop design distributes stress evenly across two connection points, reducing wear at stress concentration zones. While the supplier does not specify a tensile rating, chains of this geometry and material in the Chinese manufacturing sector commonly meet or exceed ISO 9001 general engineering chain standards. The absence of plating or coating means it is suitable for dry environments or where subsequent treatment is planned.

Buyers in logistics, agriculture, and light manufacturing use this chain for securing cargo, anchoring equipment, and temporary rigging. Packaging is supplied in 10-meter coils, wrapped in polyethylene and secured with steel strapping. Minimum order quantity is not stated and must be confirmed directly with the supplier. Lead time is not specified, but standard production cycles for similar chains in Dongguan typically range from 15 to 25 days after order confirmation. Incoterms are negotiable, with FOB Guangzhou being the most common export term.
