At the headquarters of sia Abrasives in Frauenfeld, Switzerland, we develop complete abrasive systems tailored to specific requirements and applications for the treatment of all surface types.

sia Abrasives employs about 1400 people and is represented in more than 80 countries.

With the commissioning of Maker 5, the world's most modern abrasives production plant, we once again raised the bar. At our location in Frauenfeld we produce and fabricate coated abrasives for perfect surface treatment of automobiles, wood, natural materials, metals, innovative composite materials and wood based panels.

Frauenfeld stands not only for the future of abrasives production, but also for the tradition of sia Abrasives. Our company was founded here, in the capital of the Canton of Thurgau, in 1867 and began producing coated abrasives in 1875.
