Vitrified clay

Clay has been used for approximately 5000 years and our suppliers have been producing it since 1935. Since 1987, the vitrified clay pipes and fittings have been manufactured in a new factory, based on a German technology. Our suppliers have British and American consultancy as well as highly qualified workers.
