PDI’s corporate identity was designed with the concept of infinity where there was neither boundary nor limitation - by using the cursive letters of p d and i. The letters pd were abbreviated from Padaeng and the letter i from Industry, formed together as pdi. The pd letters were linked together as an infinity symbol in order to communicate the company’s endless mission to grow steadily with innovation and determination to respond to client’s needs as well as to operate its business under environmental friendly conditions.
