Rusted tubes after they have been repaired, welded, and coated prior to being put their intended uses. The largest tubes are 78′ long, 3′ in diameter, made of 3/4″ steel. After being refurbished, they’re coated for their next use. The shiny colored tubes reflect light in surprising ways. The rusted tubes can be seen on the Horizontals: Rusted page under Exhibits.
