ALPRO-ATT d. O. O. Is privately owned company, founded in 1992. In the beginning the firm was only in the trade business with drainage and sewage material. In 1995, based on our experience, we started our own manufacturing of the sewage pipes. As the time was passing by, we expand our manufacturing capacity and increased personnel number. Special attention has been dedicated to technology development, organization of the personnel and increasing of our part and quality (products and presentation) on the market. As the result of numerous researching, new thermoplastic materials (PE and PP) had been leaded into the manufacture. In September 2002 ISO 9001: 2000 standard has been assessed for manufacture of PP fittings and PVC pipes for water and drainage, PEHD pipes for drinking water. At the moment, yearly capacity of manufacture of the PVC is 8. 500 tons, of the PE 1. 000 tons and 100 tons of the PP. We will do everything to keep this trend of development in the future, to stay the best partner to our currently partners and to become your new best partner.
