SummaryHEBEI DOUDOU METAL FENCE PRODUCTS CO., LTD. is a Chinese manufacturer established in 2015, operating as a limited company with 22–28 employees and an affiliated company. It holds ISO9001:2015, ISO14001:2015, and ISO45001:2016 management-system certificates, operates five production lines, and has 6–10 quality-control staff. The supplier reports an available SDK and broad product scope covering metal products, fencing-related equipment, surveillance systems, unmanned systems, optoelectronic devices, batteries, and software development. Export capability is supported by a valid import/export license and stated service terms, but overseas service infrastructure is limited: no overseas warehouse, showroom, agent, or branch is reported. Service procedures exist for supplier assessment, corrective actions, and complaints, but written records are unavailable. Financial information identifies years but provides no assessable performance values. No OEM service for popular brands is reported, and customer cases are...

Supplier typeThe supplier is identified as a manufacturer and limited company based in Hebei, China, established in 2015. It is also reported to have an affiliated company, indicating a corporate relationship beyond the standalone legal entity.

CertificationsThe supplier reports holding ISO9001:2015, ISO14001:2015, and ISO45001:2016 certificates, covering quality, environmental, and occupational health and safety management systems. These explicitly stated certifications support a positive assessment for management-system certification.

R&D capabilityThe supplier explicitly reports R&D capability with an available SDK and includes software development, cloud-computing devices, optoelectronic products, intelligent unmanned systems, and new-energy equipment in its business scope. However, total R&D engineer experience is stated as two years, so the evidence supports the existence of innovation-related capability but does not establish a high level of maturity.

Production capacityThe supplier is a manufacturer with five production lines and 6–10 quality-control staff. Its stated total workforce is 22 in one slice and 28 in another, while export capacity is supported by a valid import/export license; these facts provide explicit evidence of operating production and export capability.

Customization capabilityThe available SDK and broad scope spanning metal products, surveillance systems, unmanned systems, optoelectronics, batteries, cloud-computing devices, and software development indicate technical and product-development breadth. Nevertheless, the supplier explicitly reports that it does not provide OEM services for popular brands, and no direct evidence of customized manufacturing or private-label capability is provided.

Product Q&A

Q:What is the working principle of the system?

It uses a vibrating fiber where a laser emits light coupled into a two-core sensing fiber. External vibrations cause phase changes in the light wave, creating a Mach-Zehnder interference signal detected by a photodetector.

Q:What is the alarm response time?

The system ensures an alarm response time of less than 3 seconds.

Q:What is the maximum length of the defense zone?

The length of the defense zone can be up to 1000 meters.

Q:What is the working voltage?

The working voltage is 12VDC.

Q:Is OEM or ODM service available?

Yes, both OEM and ODM services are available.
