Flooring material comprising sheet-shaped floor elements (1) with a mainly square or rectangular shape. The floor elements (1) are provided with edges (2), a lower side (5) and an upper decorative layer (3). The floor elements (1) are intended to be joined by means of joining members (10). The floor elements (1) are provided with male joining members (10.sup.I) on a first edge (2.sup.I) while a second edge (2.sup.II) of the floor elements (1) are provided with a female joining member (10.sup.II). The male joining member (10.sup.I) is provided with a tongue (11) and a lower side (5) groove (12) while the female joining member (10.sup.II) is provided with a groove (13) and a cheek (14), the cheek (14) being provided with a lip (15). The floor elements (1) are provided with a male vertical assembly joining member (10.sup.III) on a third edge (2.sup.III) while a fourth, opposite, edge (2.sup.IV) is provided with female vertical assembly joining member (2.sup.IV). The floor elements (1) are alternatively provided with a male vertical assembly joining member (10.sup.III) on a third edge (2.sup.III) while a fourth, opposite, edge (2.sup.IV) also is provided with male vertical assembly joining member (2.sup.III). Adjacent male vertical assembly joining members (2.sup.III) are hereby joined by means of a separate vertical assembly joining profile (30). Two adjacent edges (2) of a floor element (1) can hereby, at the same time, and in the same turning motion, be joined with a floor element (1) adjacent to the first edge (2.sup.I) and a floor element adjacent to the third or fourth edge (2.sup.III and 2.sup.IV respectively).

Vertically joined flooring material comprising floor elements (1) with a mainly triangular, square, rectangular, rhomboidal or polygonal shape, as seen from above. The floor elements (1) are provided with edges (2) which are provided with joining members (20), a lower side (5) and a decorative top surface (3). The flooring material comprises a combination of at least two types of floor elements (1), which types comprises female floor elements (1') and male floor elements (1"). The female floor element (1') is provided with a female joining member (21) on at least half of the number of its edges (2) and a male joining member (22) on less than half of the number of its edges (2). The male floor element (1") is provided with a male joining member (22) on at least two thirds of the number of its edges (2) and a female joining member (21) on less than one third of the number of its edges (2.) An optional joining profile (50) possibly constitutes a junction between two adjacent male joining members (22) of two adjacent floor elements (1).
