The arms were granted on September 24, 1959. The arms show a red pale in gold, which is based on the bar of the arms of the Counts of Moers and the colours of the Duchy of Kleve as parts of the municipality belonged to Moers and Kleve. The three salt crystals symbolise the salt mining as well as the three former municipalities.
