HISTORY
In 1915, Andrés Santiago Álvarez created in Salamanca a company dedicated to the steel warehouse and the manufacture of agricultural tools, bars and horseshoes.
After a few years and to the death of the founder in 1941, his children take charge of the company and it is denominated Viuda de Andrés Santiago.
In 1962, the company becomes Hierros Andrés Santiago Zarzuelo. It continues with the management of steel warehouse, incorporates the sale of cold rolled pipe, profiles and especially in the distribution of sheet steel.
In 1970, it began its production of pipes with longitudinal and circular welding, and in 1978 it created TASZ (Talleres Agrícolas Santiago Zarzuelo), which continued with the same activity until 1992, when the company took a step forward and start to the manufacture of helically steel pipes, achieving greater breadth in the range of pipes and higher quality in the final product result.
Since then, the procedure has been improved, improving the processes of quality and production, while being accompanied by the most advanced technology.
Today they are the third and fourth generation (Andrés Santiago Mariño and Andrés Santiago González) who run the company (TASZ TUBOS Y ACEROS, S.L.) giving a change to the business and focusing the future on international projects. They are active with 7 helical machines and 4 rollers that allows them to adapt to the current market and give a fast and quality service.
