AI-Powered supplier vetting
SummaryQingdao Vanhon Machinery Technology Co., Ltd. is identified as a trading company and limited company offering vehicle lifts, simple parking lifts, lift accessories, and hardware accessories. It reports OEM service for popular brands, broad customization options, inventory capability, and substantial export orientation, with Europe and North America listed as primary markets. However, the supplier has only four employees and one R&D engineer, launched no new products in the previous year, has no available SDK, and holds no stated management-system certifications. Quality-control evidence is weak: test equipment is reported as zero, while quality assurance and traceability statuses are unknown. Written procedures are absent for corrective actions and complaint handling. Financial records are referenced for three years, but no financial results are provided. No specific customer cases are disclosed, although OEM service for well-known brands is explicitly claimed.
CertificationsThe supplier’s certification of management systems is explicitly recorded as “NIL.” No certification is identified in the provided information, so there is no evidence of certification-based compliance strength.
After-Sales capabilityThe supplier has inventory service capability and accepts multiple payment methods, but it has no written procedures or records for corrective and preventive actions or effective customer-complaint handling. Its service-capability assessment has relevant records but no written procedure, and it has no overseas warehouse or showroom.
R&D capabilityThe supplier reports one R&D engineer with one year of total R&D experience, launched no new products during the previous year, and has no available SDK. These explicit indicators show limited demonstrated innovation activity, although design and customization services are available.
Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. This is direct evidence of broad customization service coverage.

A:
Our threaded rods support global mainstream standards, including DIN975, DIN976-1 for European & Middle East markets; ASME B18.31.3, ASTM A307 Grade A, ASTM A193 B7 for North American projects. All threads follow ISO 965-1 6g tolerance for perfect nut matching.
Q:What tensile grades are available for carbon steel threaded rod?
A:
We supply complete carbon steel strength grades: 4.8, 5.8, 6.8, 8.8, 10.9 and 12.9 threaded rod, covering light-load decoration to heavy-duty industrial fixing demands.
Q:What anti-rust surface finishes can I choose for all thread rod?
A:
Multiple coatings optional: electro-galvanized, hot dipped galvanized, Dacromet for carbon steel; Xylan, PTFE/Tef1on coating specially for ASTM A193 B7 high temperature stud bolts.
Q:What is the difference between threaded rod and stud bolt?
A:
Classified by length: fully threaded bars over 1 meter are threaded rod; pieces shorter than 1 meter are stud bolts. Threaded rods are widely used for ceiling suspension, while B7 stud bolts are for high-pressure pipeline flange connection.
Q:What size range can your threaded rod cover?
A:
Thread diameter ranges M2-M100; standard factory length reaches 3 meters, custom longer sizes, cut-to-length service is supported for bulk orders.
