　　At a modular factory of China Construction Science & Technology Group Co., Ltd. in the Shenshan Special Cooperation Zone, laser cutting, automated welding and intelligent assembly work in coordination. A digital management system links design, procurement and production, generating material lists and processing drawings from design plans.

　　Its standardized production system can turn out a wall in 12 minutes and a room module in two hours. The facility has an annual capacity of up to 30,000 units and can produce different types of building modules in parallel according to project needs.

　　The expansion taking place on factory floors is also showing up in export figures. In the first half of this year, exports of prefabricated structures from seven cities under Guangzhou Customs reached 1.94 billion yuan (285.7 million U.S. dollars), up 21.2 percent year on year, with products reaching more than 190 countries and regions.

　　One modular-building producer said its export orders have risen nearly 60 percent year on year so far this year, with production scheduled several months ahead.

　　Manufacturers are also expanding their localized services overseas. SunnyJoy said it is working with third-party warehouses in markets including the United States and Australia to speed up deliveries.

　　For Chinese producers, the opportunity goes beyond shortening construction time. Their expansion overseas points to a broader shift: buildings are increasingly being designed, produced and exported more like manufactured goods.
