AI-Powered supplier vetting
SummaryThe supplier is identified as a factory and limited company with associated companies, offering a broad range of bridge, rubber, sealing, and customized products. It reports 10 production lines, defined product output, six to ten quality-control staff, and export experience of 10 years, with exports representing 41%–50% of total sales. The supplier provides extensive customization and ODM services and reports new products during the past year. However, no supplier-management-system certification is reported, and its service-capability procedures lack written records for assessment and corrective/preventive actions. Complaint handling has a clear procedure with follow-up records. The supplier has no overseas warehouse, showroom, agent or branch, or offline trade-show participation. Financial credibility cannot be assessed from the available non-financial information.
Supplier typeThe supplier is explicitly classified as a factory and limited company, with associated companies and manufacturing as the industry of those companies. This supports direct manufacturing status rather than a trading-only profile.
CertificationsThe supplier-management-system certification field is explicitly reported as NIL. No certification evidence is provided for this field, indicating a stated lack of supplier-management-system certification.
After-Sales capabilityThe supplier has a clear customer-complaint handling procedure with follow-up records, which is positive evidence for after-sales issue management. However, assessment and corrective/preventive-action procedures have no records, so the service system is only partially documented.
R&D capabilityThe supplier reports new products during the past year and provides ODM services, indicating active product-development capability. However, it reports no available SDK, which limits evidence of software-development or integration capability.
Production capacityThe supplier is a factory operating 10 production lines, with six to ten quality-control staff and stated output across rubber culvert balloons, seismic isolation bearings, waterstops, and expansion joints. It also reports inspection instructions that are uniformly followed, supporting established production and quality-control operations.
Customization capabilityThe supplier explicitly offers customization from samples and designs, full, minor, and flexible customization, including made-to-order products with complex profiles and different materials. It also provides ODM services, demonstrating broad customization coverage.
Client casesThe supplier states that it provides OEM services for well-known brands, which is direct evidence of at least one customer-case category. No customer names, project details, volumes, or independently verifiable case documentation are provided.
Product Q&A
Q:What is a lead core rubber bearing and how does it work?
A:
A laminated rubber bearing with a central lead plug that provides hysteretic energy dissipation during earthquakes while supporting vertical loads.
Q:Q2: What vertical load and displacement can your LRB support?
A:
Vertical loads up to 30,000 kN; design displacement up to 400 mm, fully tested per EN 15129 and AASHTO standards.
Q:Q3: What is the damping performance of the lead core?
A:
Equivalent viscous damping of 25-30%, reducing seismic forces by effectively absorbing earthquake energy through lead plastic deformation.
Q:Q4: What makes LRB different from conventional elastomeric bearings?
A:
The lead core adds high damping without external devices-- one unit combines load bearing, isolation, and energy dissipation.
Q:Q5: What certifications and test reports do you provide?
A:
ISO 9001/14001/45001, CE (EN 15129:2018, ICR/VC/HE240505), and CNAS-accredited type inspection (Report A34915F202510476).
