Supplier typeThe supplier is a Chinese limited company and a combined business entity focused on technology and service, engineering contracting, material testing, agricultural machinery, bearings, rolling elements, and OEM-related products. Its stated product and service scope indicates a manufacturer and engineering/service provider rather than a narrowly specialized trading company.

CertificationsThe supplier explicitly reports ISO9001:2015, ISO14001:2015, and ISO45001:2016 certificates, along with other unspecified certifications. These cover quality, environmental, and occupational health and safety management systems.

Production capacityThe supplier reports six production lines, 21–30 quality-control staff, one-month off-peak lead times, and two-to-three-month peak-season fulfillment times. These explicit operating and quality resources support production capability, although no product-specific capacity or output volume is provided.

Client casesA trade-related listing associates the supplier with buyer ZEN S A INDUSTRIA METALURGICA and a steel roller product for automotive starter-motor components; the record also identifies Brazil as an import country. This is a concrete customer-related reference, but only one buyer is provided and the transaction scope or performance cannot be verified from the slices.
