Q6: Can you custom-mach the tooth geometry for my bridge?

A: Yes. Send your deck drawing and movement data -- we CNC-machine the tooth profile and provide load calculations for your design review.

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:Q1: Do water and debris fall through the gaps between teeth?

A: Gaps between interlocking teeth are minimal at the riding surface, and an optional EPDM strip beneath the teeth catches drips and blocks debris before it reaches piers and bearings below.

Q:Q2: How noisy is a finger joint compared to other types?

A: Steel-to-steel contact creates a mid-level hum, quieter than open finger designs but louder than rubber joints. Optional damping inserts reduce impact noise for residential areas.

Q:Q3: Can individual tooth plates be replaced if damaged?

A: Yes. Each plate is bolted independently -- a damaged tooth is swapped without removing the entire joint or cutting concrete.

Q:Q4: Does it work on curved or sloped bridge decks?

A: Yes. Tooth plates are CNC-cut to follow deck curvature and slope -- the comb profile adapts to alignment without extra components.

Q:Q5: How does it perform in snow and ice conditions?

A: Zinc-coated steel sheds ice better than rubber surfaces, and the flush profile resists snowplow blade damage. De-icing chemicals do not affect the coating.
