Galvanized movement bead is manufactured to BSEN 10327-DX51D+275. It is used to form movement joints in plaster or render where long wall runs either have movement joints in situ or where there is a need to allow for differential or thermal movement. The bead consists of two plaster stop lengths joined by a white pvc extrusion which allows for up to 4mm of movement and is covered by a vinyl tape which is removed after plastering or rendering. For internal use only.
