Catwalks are architectural elements found in Portal 2, usually in behind the scenes sections of the game. They are constructed from a series of models found under the prefix hanging_ in the folder props_bts. They can be placed in the game as a prop_static using these as world models. There are also animated versions of catwalks with no collision found in the folder catwalk_destruction, which are catwalks being demolished.
