For four years, the Steel.In, otherwise known as the "Eiffel Steel Architecture Trophies", have been held. These awards help to make known various and significant architectural works, made in whole or in part thanks to the steel material. The Eiffel trophies are a distinction of national stature, awarded by an independent jury, to works built in France, designed by architects without nationality restrictions. These awards are part of a promotion of metal architecture and its designers, architects and engineers. They also have the ambition to highlight the know-how of metal construction and metalworking companies and all the qualities of the steel material. Each project can claim a prize if it corresponds to one of the following categories: Crossing, Living, Working, Learning, Entertaining or Traveling.
