发明名称 Process for obscuring corrugations in a window well
摘要 A process for obscuring corrugations in a window well employing painting on a metal surface a solid variegated pattern using perspective to create a three-dimensional effect on the face. Preferably, such painting occurs prior to the forming of the window well. In a preferred continuous process, a roll of metal is cut prior to the forming into a piece having such dimensions as to permit the piece to be formed into a single window well. The preferred metal is steel. And the solid variegated pattern using perspective to create a three-dimensional effect on the face can be a pattern of brick, stone, or the like, with granite being the preferred pattern.
