Open the CIPO recordAbstract From the Canadian patent
A storage tank, such as a water tower is disclosed made by bolting rows of glass-coated steel plates together. The plates overlap each other side to side and above and below. The contact with plates at the diagonal corners is not an overlapping contact but an abutment contact, and the lines of abutment contact are staggered row to row. This arrangement leads to a very efficient use of material, and to an inherently leak proof structure when the plates are arranged to form a double skin in the lower regions of the tower.
