The first manufacturing operations – albeit very few in number – for precast elements were set up after the proclamation of the Socialist Republic of Vietnam towards the end of the seventies. These factories produced mainly for housing construction. The reinforced elements were manufactured using employees inexperienced in the trade who had been assigned to production brigades from veteran cadres. Unfortunately, their consciousness of product quality and sustainability had evolved rather poorly. The end result of this type of manufacturing method is that a negative product image is communicated: precast elements are simple, rudimentary products with unacceptable resistance to ageing, doomed to rapid degeneration. However, the last ten years have seen the creation of a constantly growing number of operations for producing prestressed reinforced concrete in both the north and the south of the country.
