The K-3 chequer brick manufactured in the Radoszyce brickyard is characterized by high mechanical performance and very good aesthetic values. The product is made from clay, in a traditional manner, without the addition of ashes. The product is sorted by hand, therefore the brick pallets have virtually no deficiencies.
Application: in common and structural walls, brick columns, partition walls, chimney flue casings.
