Key features

The multi-chamber hollow design creates an air isolation layer inside the strip, effectively blocking heat transfer and absorbing outside noise to save energy and reduce indoor noise.

Made of flexible EPDM rubber, it fits closely with door and window frames under compression. It reliably blocks wind, dust, rain and cold air for long-term airtight waterproof performance.

It resists UV radiation and extreme temperatures without cracking, and can be freely cut to match aluminum and plastic steel windows.

AI-Powered supplier vetting

SummaryThe supplier identifies itself as a factory and reports broad customization, ODM, OEM for well-known brands, raw-material traceability, and 100% finished-product inspection. It has export experience, self-operated import/export rights, overseas installation and maintenance services, and stated production of approximately 20 production lines annually. Evidence also indicates more than 200 domestic and overseas rubber-enterprise customers. However, the supplier lacks written procedures or records for service assessment, corrective and preventive actions, and complaint handling; it also reports no valid manufacturing-capacity contract with related subcontractors, no overseas warehouse or showroom, and no available SDK. Certification evidence is limited to a company description referencing an ISO 2000 management system, without documentation or a clearly identified certification standard.

Supplier typeThe supplier explicitly identifies its company nature as a factory. Its description also presents production capacity and equipment-related manufacturing activities, supporting classification as a manufacturing supplier rather than only a trading or service entity.

R&D capabilityThe supplier reports new products within the past year, ODM service availability, and broad R&D design services. It does not have an available SDK, but the evidence still explicitly supports active product development and design capability.

Production capacityThe supplier reports lathe and drilling-machine facilities, in-stock capability, and annual production of about 20 production lines while serving more than 200 rubber enterprises. A deficiency is indicated by the absence of a valid manufacturing-capacity contract with related subcontractors, but the stated factory capacity and equipment support production capability overall.

Customization capabilityBoth R&D and design-service records list customization from samples, designs, minor customization, flexible customization, and full customization. This is explicit evidence of a broad customization offering.

Client casesThe supplier reports OEM service for well-known brands, serving more than 200 well-known rubber enterprises domestically and overseas, and exporting for 16 years with 51%–70% of sales from exports. These statements provide substantial customer and market-experience evidence, although individual customer names or documented case studies are not supplied.
