AI-Powered supplier vetting

SummaryThe supplier is identified as a manufacturing factory in Yangzhou, Gaoyou, focused on high-performance special steel wire rope production and R&D. It holds ISO9001:2015 and CCS certifications, reports OEM service for well-known brands, ODM capability, recent new-product activity, and multiple customization options. Technical engineers support customer-request confirmation, product design, production, and after-sales service. However, R&D audit documentation and an SDK are unavailable. The supplier reports in-stock capability and stated lead times, but lacks overseas warehouses, showrooms, agents or branches, and offline trade-show participation. No valid manufacturing-capacity contract with related subcontractors is reported. Financial, sustainability, and digitalization information is insufficient for a firm assessment.

Supplier typeThe supplier is explicitly classified as a factory in the manufacturing industry and is described as focusing on production and R&D of high-performance special steel wire rope. This supports a direct-manufacturer profile rather than a trading-only supplier.

CertificationsThe company states that it has passed ISO9001:2015 quality system certification and CCS China Classification Society certification, with product quality controlled within the enterprise. These are explicit certification credentials relevant to manufacturing quality and classification compliance.

After-Sales capabilityTechnology engineers are responsible for providing technical support for production and after-sales service. However, the supplier has no overseas warehouse, showroom, agent, or branch, so the evidence supports technical after-sales assistance but not broad overseas service infrastructure.

R&D capabilityThe supplier reports new products during the past year, ODM services, multiple R&D-related customization modes, and engineers responsible for new-product design and technical support. Nevertheless, no R&D audit documentation is available and no SDK is available, so the evidence demonstrates product-development activity but not fully documented or SDK-based innovation capability.

Production capacityThe supplier is a manufacturing factory with stated production and R&D focus, in-stock capability, documented procedures and records for service-capability assessment, stated peak-season lead time of one month and off-season lead time within 15 workdays, and facilities including a drawing machine, stranding production line, and rope-closing machine. However, no valid contract exists with related subcontractors, which creates a documented weakness in subcontracted manufacturing capacity governance.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, minor customization, and full customization. Its technology engineers also confirm customer requests and design new products, providing direct support for customized development.

Client casesThe supplier explicitly states that it provides OEM services for well-known brands, which is evidence of at least one category of customer experience. No customer names, project details, volumes, or performance records are provided, so the breadth and verifiability of its customer cases remain limited.

Product Q&A

Q:What does 'WS' stand for in 6x36 WS construction?

'WS' stands for Warrington-Seale. It is a specialized line-contact construction that combines different wire sizes in each strand. This creates a very dense and stable structure with a smooth outer surface, providing the best balance of flexibility and abrasion resistance.

Q:Why should I choose 6x36 WS instead of 6x19 or 6x25?

If your application involves frequent bending over sheaves (like cranes), 6x36 WS is the superior choice. With 36 wires per strand, it is much softer and has a significantly longer bending fatigue life. It typically lasts 30-50% longer than 6x19 in high-cycle lifting environments.

Q:Is 6x36 WS suitable for small diameter drums and sheaves?

Yes. One of the main advantages of 6x36 WS is its extreme flexibility. It can handle smaller bending radii better than stiffer constructions, which reduces internal stress and prevents premature wire breaks on smaller equipment.

Q:Should I use a Steel Core (IWRC) or Fiber Core (FC) for my crane?

For almost all modern cranes and heavy lifting, we strongly recommend IWRC (Independent Wire Rope Core). It provides higher breaking strength, better structural stability, and superior resistance to crushing when the rope is wound in multiple layers on a winch drum.

Q:How does 6x36 WS perform in corrosive marine environments?

We offer Hot-Dipped Galvanized 6x36 WS specifically for marine use. When combined with our heavy internal lubrication (A2 grade), it provides excellent protection against saltwater corrosion and internal friction in offshore winches and port cranes.
