The Tosno plant of prefabricated reinforced concrete structures "Stroydetal" was built in 1957 according to the project of "Lengiprotrans" on the basis of a construction yard. The production capacity of the enterprise was 12 thousand m3 of products per year. In subsequent years, the institute was engaged in the improvement of the plant.
In 1959-1961, the Tosno plant was reconstructed, as a result of which its design capacity increased to 43 thousand m3 of products per year. The plant began to produce products for large-panel houses of the 1-335 series.
In 1965, the plant was transferred to the manufacture of products for residential buildings of the 1-467a series, while its design capacity increased to 45 thousand m3 of products per year.
In 1981, according to the project of the institute, a production building and a complex of new auxiliary buildings and structures were built for the transfer of the Stroydetal plant to the production of large-panel houses of a promising series. This made it possible to increase the plant's capacity to 90 thousand cubic meters. m3 per year of precast concrete.
