Thailand's ARCHITECT EXPO 2020 is the most prestigious and largest international building materials exhibition in Southeast Asia. The exhibition has taken place for more than 30 years and will enter its 34th in 2020. This year's theme "Refocus Heritage", we hope to increase public awareness and understanding of "old building" protection and maintenance. In 2019, more than 750 manufacturers from around the world exhibited in Thailand's ARCHITECT EXPO 2020 and 440,000 professional buyers visited. It is an annual event that Taiwan's green building materials industry cannot miss.
