It offers broad customization and ODM services, uses SolidWorks and CAD, and maintains R&D documentation for design inputs, outputs, reviews, verification, and validation. The supplier reports ISO9001 certification, product traceability, documented inspection procedures, quality assurance, and complaint-handling procedures. Production information lists capacity for weight benches, power racks, dumbbells, and barbells, supported by cutting and welding equipment. It also reports OEM service for well-known brands and cooperation with world-renowned brands, but no specific customer names or verifiable case details are provided. Financial records are referenced for 2022–2024, but the slices provide no financial figures or sufficient information to assess financial strength. A recent approved-supplier list is unavailable.

Supplier typeThe supplier is identified as a professional fitness equipment manufacturer integrating R&D, production, and sales, with business activities covering sports goods and equipment, hardware, and related products. Its stated commercial trade engagement is sporting goods and recreation, supporting classification as a fitness and sporting-goods manufacturer rather than only a trading company.

After-Sales capabilityTechnology engineers are responsible for confirming customer requirements and providing technical support for after-sales service. The supplier also reports clear, followed procedures and records for handling customer complaints, indicating an established after-sales and complaint-management process.

R&D capabilityThe supplier reports launching new products during the past year, providing ODM services, using SolidWorks and CAD, and maintaining auditable R&D design and validation documentation. It also states that it has multiple patents and cooperates with world-renowned brands; however, no SDK is available, which limits evidence for software-instrument development.
