Import Cup Chain — Buy in Bulk from Supplier in China

The Cup chain supplied by Qingdao Wings Co., Ltd. is constructed from brass, copper, and steel components, with each link designed for mechanical durability and corrosion resistance. The chain is available in custom lengths and configurations, with standard link diameters ranging from 6 mm to 12 mm and pitch lengths between 15 mm and 25 mm, depending on application requirements. Surface coating is applied to enhance resistance to oxidation in humid or saline environments, a common requirement in marine and industrial settings.

The material composition follows typical industry standards for load-bearing chains, where brass provides lubricity and copper contributes to thermal conductivity, while steel ensures tensile strength. These chains are not plated or galvanized but rely on alloyed metal properties and protective coatings to maintain integrity. Typical wear resistance aligns with ISO 9001-compliant manufacturing practices, though no formal certification is stated by the supplier. Variants include plain finish and coated versions, with the latter preferred for outdoor or high-moisture use.

This chain is commonly used in lifting equipment, conveyor systems, marine rigging, and decorative architectural installations. Buyers include industrial equipment manufacturers, construction contractors, and specialty retailers in the decorative hardware sector. Trade terms are flexible, with packaging typically in polyethylene-lined cartons or wooden crates for bulk shipments. Minimum order quantities are not specified, but the supplier accommodates custom orders for volume buyers. Delivery is arranged under FOB or CIF terms from Qingdao port.
