Foshan alone is home to more than 300 exporters of prefabricated buildings. Across the industry, modular structures are being used for hotels, dormitories and offices, while some manufacturers are branching into customized outdoor spaces.

　　At SunnyJoy Intelligent Technology Co., Ltd., the glass roof of a modular outdoor room slides open under electric power. Made up of 13 modules, the structure attracted attention at this year"s 139th Canton Fair.

　　"Three adults can assemble it in two and a half hours by following an installation video," said Zhang Yong, the company"s general manager.

　　The company"s products sell well in North America and Oceania, while emerging markets in Africa and Southeast Asia are also growing rapidly. Social media has become an important source of overseas customers: SunnyJoy has built a following of around 10 million across domestic and overseas platforms, with online channels generating more than half of its customer inquiries.

　　Behind such products is the Pearl River Delta"s manufacturing network. Zhang said a single outdoor structure can involve dozens of suppliers, with everything from frames and worktops to drive systems and lighting sourced within the region.

　　That proximity allows manufacturers to adjust designs, upgrade components and respond quickly to changing customer requests. As products become more integrated, companies are also expanding into higher-value offerings that incorporate solar glass, energy storage and intelligent control systems.
