Sliding structural expansion joint entirely realised in aluminium. Designed to bear structural movements of large sized buildings or compounds of buildings.
They are installed over the spaces existing between two semi-detached parts of a building of smaller entity or between different beam bays. They can connect and close these inter-spaces adjusting themselves up-wards, downwards and even transversally, according to the shrinkage-settlement movements of the whole building, either cyclic or permanent.
