The present invention relates to a method for the production of a prefabricated panel (10), with two opposing side edges (12, 14) shaped respectively with a male profile and a female profile that can be joined together, comprising at least: - an operation for forming said panel (10) to give at least a first side edge (12) a male profile (13) and to give at least a second opposing side edge (14) a female profile (15) that can be joined together; and - an operation for finishing said side edges (12, 14) to give them dimensional and form tolerances that allow dry joining of adjacent panels to create circular tanks; characterized in that said forming operation and said finishing operation are carried out in a single step. |
