In line with the trend of using precast concrete in many construction areas, i.e. transport infrastructure (piles, girders), factories/industrial buildings (piles, beams, columns, floors, walls...), slope protection (prestressed reinforced concrete sheetpiles), underground constructions (tunnel lining), FECON has continously kept on researching, investing and building precast concrete factories to serve the construction needs. These include the two PC, PHC pile manufacturing factories in Ha Nam and Thanh Hoa provinces with the brand FECON Pile, operating since 2015. In 2018, FECON signed a joint venture with Song Day Construction Materials JSC and Japanese partners: Nippon Concrete, Asahi Concrete and Global Works to establish a tunnel lining manufacturing factory in Bac Ninh province, guarranteeing the supply of tunnel linings exclusively to all metro projects in Viet Nam. Besides, prestressed reinforced concrete sheetpiles factory is in the stage of investment feasibility study.
