Foshan, in Guangdong province, is one of China's most concentrated building-materials manufacturing bases. Its aluminium, hardware and interior fit-out supply chains grew alongside the ceramics and sanitaryware industries in the Pearl River Delta, and partition manufacturing sits directly on top of them.
For partition buyers this matters because the upstream materials — aluminium extrusion, hardware, seals, panel cores — are produced locally. A Foshan manufacturer is typically within a short drive of its own material suppliers, which shortens lead times and makes customisation of profiles and finishes more practical than in regions where everything must be shipped in.
The city's manufacturers tend to range from large aluminium-system producers who add partition lines, to smaller specialist workshops focused on a single system type. Both exist in the same industrial zones, which is why prices for apparently similar products vary so widely in Foshan.
