Built one factory at a time
Truong Thanh Aluminium Manufacturing was licensed by the Hanoi Department of Planning and Investment on 16 May 2016 under registration number 0107434521, and construction started the same year on a single plant in the Quat Dong industrial cluster, south of the city.
The company now runs six factories. Four of them stand together at Quat Dong on 25,000 m²; a fifth was built at Nam Thuan in Duc Hoa, Long An, to serve the southern market; and a high-tech silicon plant was added in Ha Nam. Between them they hold 16 extrusion lines, four powder coating lines and three electrophoretic lines, with an in-house die shop producing 500 dies a month.
Profiles go out under the GOLD DOOR brand through more than 350 dealers covering all 63 provinces and cities of Vietnam, supported by a staff of over 350. Development of export markets beyond Vietnam began in 2025, which is what this site exists to carry forward.
