description A method and an apparatus for forming a male/female metal panel tile are provided to prevent a metal panel from being deformed and broken during a press forming process for forming stepped portions in valleys through a provisional forming process for the metal panel. A method for forming a male/female metal panel tile comprises a step of forming a plurality of mountains and valleys in a metal panel in the longitudinal direction of the metal panel by allowing the metal panel to pass through a forming roll of a roll forming machine(S10). A plurality of small valleys are formed in the metal panel in the transverse direction of the metal panel(S20). Corrugation patterns are formed only in the mountains of the metal panel through a pressing process(S30). Corrugation patterns and stepped portions are formed only in the valleys of the metal panel through the pressing process(S40). The metal panel is cut by a cutting device by a desired length(S50).
