SummaryThe supplier is a limited company engaged in the production, processing, and sale of stainless steel standard parts, fasteners, and related metal products, including nuts, thread rods, and bolts. It identifies as a professional technical supplier and reports four R&D engineers supporting customer-request confirmation, product design, production, and after-sales technical service. Customization is available from samples, designs, and full or minor requirements, but 3D software design and SDK capabilities are unavailable.

Supplier typeThe supplier is identified as a limited company with a combined business type, engaged in production, processing, and sales of stainless steel standard parts, fasteners, and other metal products. Its listed products include nuts, thread rods, bolts, screws, washers, and non-standard products, supporting classification as a manufacturing-oriented technical supplier.

CertificationsThe supplier’s certification of management systems is explicitly listed as NIL. This is a stated absence of certification evidence and does not demonstrate compliance with a certified management system.

R&D capabilityThe supplier reports professional technical-supplier status, four R&D engineers, and responsibilities covering customer requirements, new-product design, production support, and after-sales technical support. Nevertheless, it lacks 3D software design and SDK availability, so innovation capability is evidenced in conventional product development but not in digital design or SDK-based development.

Customization capabilityCustomization is explicitly offered from samples, customer designs, full requirements, minor requirements, and flexible specifications. Four R&D engineers are assigned to confirm customer requests and design new products, providing direct support for customized fastener development.
