The invention provides a method of preventing heavy gauge strip steel from being scratched among finishing mill racks. The method comprises the following steps of: adjusting the elevation of a rolling line of an idle rolling mill to right elevation; and adjusting the mechanical position of a downstream loop of the idle rolling mill, to be specific, lifting the loop to the mechanical highest position, arranging a gasket on a brake bar below the loop and a sleeve on a buffer below the loop, dropping down the loop, and identifying the waiting position angle of the loop. The method has the beneficial effects that the rolling line is in the right elevation, and strip steel is lifted; the waiting position angle of the loop is increased by adjusting the mechanical position of the downstream loop of the idle rolling mill, thereby preventing the lower surface of the strip steel from scratching a lower guide plate of a rolling mill outlet, completely solving the surface scratching problem of the strip steel, greatly in
