China partition industry data
What public data shows about Chinese partition manufacturers: where they cluster, how old they are, which certifications they hold and where they export. Every figure is traceable to a public source, and the sample size is stated throughout.
About this data
Sample: 29 manufacturers, all listed in this directory and verified against public sources. This is a sample of companies with verifiable public information, not a census of the industry. Certification and export figures count what companies publicly state — a manufacturer without a listed certificate may still hold one that it does not publish.
Regional concentration
Partition manufacturing in this sample is overwhelmingly concentrated in Guangdong province, and within it in two cities — Foshan and Guangzhou. The two sit roughly 30km apart and share the same upstream supply base of aluminium extrusion, hardware and panel materials.
Company age
Of the 22 manufacturers with a publicly stated founding year, the oldest dates from 1997 and the median from 2008. 16 were founded in 2010 or earlier, and 6 after that — suggesting a mix of long-established aluminium-system producers and a newer generation of specialist partition companies.
Certification coverage
Certification mentions across the sample. These count what appears in public material and should be read as a floor rather than a ceiling — many factories hold test reports they only share during an enquiry, and Chinese-language certificates frequently do not appear on English sites.
Export markets
Export destinations stated publicly by manufacturers in the sample. Europe, the Middle East and Southeast Asia appear most consistently, which reflects both genuine export activity and the markets where Chinese factories invest in English-language marketing.
Transparency score distribution
The median Factory Score across the sample is 44.3 out of 100. This is a transparency metric — it measures how much verifiable information each company publishes, not product quality. A low score means the company documents little publicly, not that it manufactures poorly.
Limitations
- ·Sample size is 29 companies. It is not a census and should not be presented as industry-wide statistics.
- ·The sample skews towards manufacturers with English-language web presence, which is itself concentrated in Guangdong.
- ·Certification counts reflect public statements. Unlisted certificates are not captured.
- ·Export markets reflect what companies claim publicly and are not independently verified per shipment.
- ·Figures are a snapshot and are updated as the directory grows.

How large is the sample behind this data?
29 manufacturers, all of which are listed in this directory and have been checked against public sources. This is not a census of the Chinese partition industry — it is a sample of companies with verifiable public information. Figures should be read as indicative of the verifiable segment of the market, not the market as a whole.
Where does this data come from?
Every field is taken from public sources: company websites, business registries, certification records and B2B platform listings. Each manufacturer's profile page links the individual data points back to their source. No figures are estimated or interpolated.
Why is Guangdong so dominant in the data?
24 of the 29 manufacturers in this sample are based in Guangdong province, reflecting the province's aluminium, glass and interior fit-out supply chains. It also reflects where English-language export marketing is most established — factories elsewhere in China may be equally capable but publish less material that can be verified from outside China.
Can I cite this data?
Yes. Please cite it as "China Partition Factory, China Partition Industry Data" with a link to this page. The sample size (29 manufacturers) should be stated alongside any figure, because it materially affects how the numbers should be read.
