Gres Panaria Portugal S.A. was established in 2006, when the second industrial unit of the Panaria Group in Portugal was acquired. Gres Panaria S.A., integrated in the prestigious Italian group Panariagroup Industrie Ceramiche S.p.A, is one of the worldwide reference ceramic companies.

Margres is one of the leading brands in the porcelain stoneware for floorings and coatings sector. It started production in its industrial unit of Ílhavo, in 1982, being then one of the first porcelain stoneware factories in the world.
Margres is exclusively dedicated to the production of porcelain stoneware, a premium product providing solutions for any type of construction in private or public spaces due to its high technical advantages. The features that make this product unique stem from the use of the most modern state-of-the art technology, high quality raw materials and an aesthetic concern that meets the contemporary architecture’s demands.
Margres is a reference brand in the domestic market and has a great presence in the international market.

In 2002 Panariagroup purchased the first industrial unit in Portugal, located in Ílhavo, manufacturing materials, namely for Maronagres, today called Margres.

Afterwards, the second industrial unit in Aveiro was purchased in 2005, a unit that manufactured materials for Novagres, which changed the name to Love Tiles in 2008, after a rebranding action.

These two industrial units have an installed capacity of 8 million m2/year. Gres Panaria Portugal S.A. employs about 400 people.

With a commercial structure of 70 agents and 8 promoters, present in more than 113 countries spread across the five continents, it provides support to a broad range of over 2000 clients.

Gres Panaria has a dedicated structure – the Product Development Department- that carries out research and development of new products in its own laboratories, always at the forefront, both in terms of quality and product design.

Besides the production and administrative units, the brands also have their own showrooms in Aveiro and Lisbon.
