Installed in January 2010 in front of the Willis (formerly Sears) Tower, this 25 foot diameter globe was made by the Poblocki Sign Company entirely out of 316 stainless steel, which was rolled, coped and fully welded at each intersection. The 16000 pound structure was fabricated in 8 sections and had a base made from 6" schedule 40 pipe. More than 8 miles of welding wire was used on the joint and splice connections of the globe. The amount of 3" schedule 40 pipe used on the project was enough to span the entire height of the Willis Tower: 1450 feet. KMF Metals, Inc polished all of this weld to a seamless number 4 satin finish working to an expedited leadtime. KMF Metals, inc was the only polisher involved on this project.
In addition to polishing the 6 sections making up the framework of the globe, KMF Metals also put a DA, random orbital finish on the continents, which were formed from 3/16" 316l stainless steel sheet.
