Dyneema Fiber Winch Line

Jiuli Rope Co., Ltd. manufactures Dyneema Fiber Winch Line using ultra-high-molecular-weight polyethylene (UHMWPE) with a braided 12-ply or 48-ply double-layer construction, as specified in their product line. The diameter range available is 4mm to 146mm, with tensile strength exceeding 3,000 MPa for standard grades. This line is designed for marine winching, offshore lifting, and heavy-duty towing where low elongation and high strength-to-weight ratio are critical.

The fiber is produced using fully automated extrusion and braiding equipment imported from Germany, ensuring consistent molecular orientation and reduced internal friction. Typical industry standards for UHMWPE winch lines include a moisture absorption rate below 0.01%, zero buoyancy, and resistance to UV degradation and saltwater corrosion. Unlike nylon or polyester ropes, Dyneema fiber retains over 95% of its strength after 1,000 hours of salt spray exposure, making it suitable for prolonged marine use without coating or treatment.

Buyers in shipbuilding, offshore oil exploration, port logistics, and defense sectors source this line for winch systems requiring minimal stretch and high cut resistance. Trade terms are typically FOB Yangzhou Port or CIF to major global ports. Minimum order quantities are negotiated per specification, and bulk orders include custom spooling and labeling. Certifications from CCS and DNV-GL are documented but must be confirmed per batch.

Jiuli Rope Co., Ltd. operates from Genggeng Industry Park in Baoying County, Jiangsu Province, China, and traces its origins to the Baoying County Rope Factory established in 1981. The company specializes in chemical fiber ropes, producing over 8,000 tons annually using automated German equipment. It is recognized by China Classification Society and DNV-GL, and has participated in drafting national rope standards since 2003. The listing confirms no headcount, revenue figures, or client names beyond its designation as a supplier to China Ship General Company.

The supplier holds ISO9001 certification and has developed proprietary composite rope technologies, including core-coated and compound ropes with patented designs. It maintains test facilities for tensile, abrasion, and fatigue performance, but does not publish third-party lab reports. No claims are made about export volume, international offices, or production capacity beyond the stated annual output. Its reputation is built on long-term industrial contracts, not marketing claims.
