Our company was originally founded under the name of Pinthong Vissavakum Partnership Limited (ห้างหุ้นส่วนจำกัด ปิ่นทองวิศวกรรม) in 1975 by Mr. Samarn Pinthongkam. Later in 1979 Mr. Samarn decided to expand into trading business; Pinthong Trading Company Limited (บริษัท ปิ่นทองการค้า จำกัด) was established to support the new business. 
On 14 February 1991, Mr. Samarn founded another company, Pinthong Engineering Company Limited, to take the place of the incumbent Pinthong Vissavakum. The establishment of Pinthong Engineering was aimed to formalize the organization and the business structure for greater management efficiency and quality. 
Pinthong Vissavakum was closed down shortly after the all the works were transferred to Pinthong Engineering while Pinthong Trading still remained up until today.
Throughout over the past 35 years, we have always run our business with integrity to ensure greatest quality and value for our customers as our vision goes “Quality, Value and Integrity to Make Our World Better, Together”

President: Mr Samarn Pinthongkam 
Managing Director: Mr. Kasarn Piyapimook
