Mission: innovation and passion since 1973

ATI DI MARIANI SRL was founded in 1973 in Cesena (FC), thanks to the vision and will to innovate and build of its founder, Mario Mariani. Fortified by the skills gained in the plumbing and heating market and by the support of a trusted team, he founded an energetic and out of the ordinary reality, based on a range of products, most of which he designed and patented himself.
The experience of our team, the strong desire to improve ourselves and the passion for our work are our biggest spurs toward the future, a strength that is necessary in order to compete in an international market day by day.


The company has approximately 60 employees, more production sites, with a total area of 38,000 square meters, 15,000 of which are covered: all the production sites are located in Cesena, in the Forli-Cesena District.

Research and Development

Looking at the over forty years of ATI’s history, we can think of only one word: progress. As a matter of facts, our reality is in continuous development, starting new projects, getting new patents and expanding its production year by year. From the very beginning, we focused on what we can do best, with undiminished tenacity, passion and dedication to work.


The production, which is fully made in our factories, is one of our greatest strengths. We put a particular emphasis in the selection of raw materials, since the quality of the finished product depends on the quality of all the elements that are involved in its production cycle. Each supply is subject to strict inspections and if it does not meet the required specifications, it is rejected.
