More than 130 years ago, the brothers Otto and Sartorius Rheinhold founded the "Vereinigte Kieselguhr and Korksteingesellschaft Rheinhold & Co" in Celle (Germany) and became well-established for their patented cork insulation material. Over the years, the successful business activities have been expanded in the maritime industry, thus laying the foundation of the R&M Group.

The Group is a global player with a large network of shipyards, ship owners, operators and architects, offering a unique and extensive portfolio of ship interior and outfitting, from single components to turnkey solutions (steel-to-steel/visual). Due to many years of experience, we have established ourselves as a renowned expert and realize projects aboard all types of ships, such as (river) cruise ships, ferries, expedition vessels and mega yachts as well as in all areas on board of ships, whether passenger, crew, utility or public areas.

R&M offers products from its own manufacturing plants, services and solutions and thus covers the entire value chain: from engineering and consulting to logistics and project management as well as repair and maintenance services. It also includes the planning and installation of thermal and acoustic insulation as well as heating, air conditioning and ventilation systems (HVAC), the production of modular furnishing systems such as walls, floors, ceilings, doors, wet units/pods, prefabricated cabins and furniture, from the standard range or custom-made designer pieces.

Certified according to the valid standard (DIN ES ISO 9001:2015), we always meet the high demands of the maritime industry and attach great importance to highest precision, high quality and sustainability. Regardless of whether it is about a new build or a refit project or extensive refurbishment work. As a long-standing supplier, we are very familiar with the processes at a shipyard and know what is important. Our customers value our expertise in combination with our reliability and flexibility. We know that every ship is different and requires individual project planning. Tight schedules and complex tasks are challenges, which we professionally deal with and meet at any time.

Tradition and consistency in changing times.
