AI-Powered supplier vetting
SummaryThe supplier is a limited company producing fasteners and related components, including threaded rods, bolts, nuts, screws, washers, brackets, and end connectors. It reports substantial stated annual production volumes and has invested in cold-heading, threading, galvanizing, heat-treatment, and automated conveyor equipment. It supports extensive customization and 3D software design services, but reports no new products in the past year, no SDK, and no status as a professional technical supplier. Service procedures for corrective actions and complaints are documented and followed, while service assessment procedures lack records. The supplier has participated in Hannover Messe 2025 but has no overseas showroom, agents, branches, or overseas service locations. No certifications, customer cases, or verified financial-credit information are provided.
Supplier typeThe supplier is identified as a limited company with five employees and no parent-group affiliation. Its product scope is centered on fasteners and related hardware, including bolts, nuts, screws, brackets, and end connectors, indicating a specialized product manufacturer rather than a diversified corporate group.
After-Sales capabilityThe supplier states that it provides a strong after-sales guarantee, and it has clear, followed procedures for corrective and preventive actions and customer complaints. However, it lacks overseas showrooms, agents, branches, and overseas service locations; its general service-assessment procedure exists but has no records.
R&D capabilityThe supplier provides 3D software design and ODM services, but reports no new products in the past year, no available SDK, and only one year of total R&D-engineer experience. It also identifies itself as not being a professional technical supplier, so innovation capability is mixed and not strongly evidenced.
Production capacityThe supplier reports annual capacities of 9,000 tons of threaded rods, 2,500 tons of bolts, and 3,000 tons each of nuts, screws, and washers. It has 60 cold-heading and threading machines, two galvanizing lines, two heat-treatment lines, and automated conveyor belts; reported lead time is one month in both peak and off-seasons, supporting a positive production-capability assessment.
Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, and it provides 3D software design services. These statements directly support broad customization capability.
