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:Q: How does the lead core absorb earthquake energy?
A:
A: The lead plug yields plastically under seismic force, converting kinetic energy into heat through deformation.
Q:Q: What happens after multiple earthquakes?
A:
A: Lead recrystallizes at room temperature. The core fully restores its damping capacity within minutes -- no replacement needed.
Q:Q: How is LRB different from a standard bearing?
A:
A: Standard bearings only support vertical load. LRB adds a lead core for 20-30% seismic energy dissipation.
Q:Q: What diameter and load range do you produce?
A:
A: 200mm to 1050mm diameter. Load capacity from 500 kN to over 10,000 kN depending on configuration.
Q:Q: How do I select the right lead core size?
A:
A: Send your bridge's PGA, design displacement, and vertical load. Our engineers calculate the optimal specification.
