摘要: A method of manufacturing a cast article including a frame that in use of the article defines an aperture; and a further component that is in use retained moveably captive relative to the frame. The method casts the further component and respective first and second frame members, the further component and the frame members being securable together to form the article, and subsequently assembles the frame members and the further component together to form the article. A gully grate results from practicing the method.
