About us

Company details

Three established brands in one place

Making use of synergies and bundling expertise, these are more than just slogans at provitris GmbH. The recently established company started trading on 1 July 2013 in Rietberg gives these slogans a completely new meaning.

mame, gral and cristallo product brands had previously been owned by DORMA-Glas GmbH in Bad Salzuflen, a company focussing on interior design with glass. The expertise of gral is based on its design and the development of innovative shower hardware and shower systems. Glass dividers are grouped together in the cristallo brand and mame represents high-grade glass door designs.

The decision to merge the brands in one location is intended to increase the individual brands' market significance. provitris GmbH is the new and competent expert for interior design using glass, providing a shared sales and marketing organisation.

The provitris GmbH is based in the former mame building in Rietberg, which has been owned by DORMA Group since 2006. The facility is ideal for all 65 employees: building and premises offer plenty of space for warehousing and production, a representative showroom and a large training centre for our commercial and industrial customers.
