In recent years, the export structure of China's foreign trade has been continuously optimized, with the proportion of intelligent and environmentally friendly products increasing, gradually replacing traditional low-end products as the mainstream of exports. Smart doors with functions such as smart door locks, sensor based door opening, and remote control, as well as wooden and steel doors made of environmentally friendly materials that meet international environmental standards, are highly favored by overseas markets. Zhejiang Difini and other enterprises have increased their investment in intelligent and environmental technology research and development, launching products such as intelligent security doors and environmentally friendly wooden doors, with export volumes increasing by over 20% year-on-year. Industry insiders point out that with the increasing global awareness of environmental protection and the development of intelligent trends, intelligence and environmental protection will become the core competitiveness of foreign trade enterprises.
