Our parent company HAN CHIA ENGINEERING CO.,LTD is located in Taoyuan City, Taiwan. With over 20 years' experience, we have contracted a lot of public construction projects. In 2014, our  professional team came out from Taiwan to Thailand at the first time. After years of accumulation, we have built factories in Thailand for many companies and received good reviews. At the same time, we have a better understanding of Thailand's land and climate. The establishment of the TREELAND team in 2015 will bring the technology from Taiwan and the  experience in Thailand to provide the owners with the most complete services.
