The male joining member is provided with a tongue and a lower side groove while the female joining member is provided with a groove and a cheek, the cheek being provided with a lip. The floor elements are provided with a male vertical assembly joining member on a third edge while a fourth, opposite, edge is provided with female vertical assembly joining member. The floor elements are alternatively provided with a male vertical assembly joining member on a third edge while a fourth, opposite, edge also is provided with male vertical assembly joining member. Adjacent male vertical assembly joining members are hereby joined by means of a separate vertical assembly joining profile. Two adjacent edges of a floor element can hereby, at the same time, and in the same turning motion, be joined with a floor element adjacent to the first edge and a floor element adjacent to the third or fourth edge.
