The Zahna clay record factory was founded not far from Berlin in 1891.
Today, Zahna-Fliesen produces porcelain stoneware tiles for the industrial sector using the latest rapid-fire technology, as well as tiles for attractive use in the renovation and restoration of historic buildings.
The production of unglazed porcelain stoneware is characterized by a variety of mineralogical transformation processes that create texture and color.
Unbeatable properties such as resistance to high loads, protection from mechanical wear and resistance to acids, alkalis and frost make up part of the quality features of our tiles.
The manufacture of unglazed porcelain stoneware is characterized by a variety of transformation processes that create texture and color. High-quality tiles are created from selected raw materials through elaborate preparation processes and computer-controlled hydraulic presses. After drying, these are baked in a roller kiln at 1,240 ° C for about two hours.
Electronic cameras and optical calibration devices ensure consistently high quality in terms of color consistency, caliber, evenness, surface properties and geometric shape. The result is a homogeneous product that has all the advantages of densely sintered porcelain stoneware.
Unbeatable properties such as high resilience, resistance to mechanical wear and the resistance to acids, alkalis and frost make up a large part of the quality features of ZF tiles.
