The Gandrup brick factory lies between Aalborg and Hals. At this brick factory over 20 different types of water-struck bricks with 4 visible sides are produced, as well as extruded bricks. The production consists of light bricks with saw dust, Moler bricks and the special Gandrup floor tiles in fired brick format.
This brick factory has been owned by the Randers Tegl group since 1967. After it was bought, the brick factory was expanded, so that the yearly capacity reached 27 million bricks. In 1989 the brick factory was extended again. Thus, the Gandrup brick factory became one of Northern Europe's largest and most rational factories, with a yearly capacity of 75 million bricks.
In 2004, the factory was granted the Danish Energy Saving Prize, as acknowledgement for its efforts to reduce energy consumption.
The factory lakes, the former three clay coolers, are today part of a beloved 25-ha wide local recreation area with a very varied flora and fauna.
