During the years of its activity, materials used in the production of metal bracelets and other stainless-steel products, have strongly evolved. PROMOTION has therefore started a few years ago a close and systematic cooperation with different steel mills to source-out and get different steels with always higher resistance to corrosion and with a purity ratio suitable for the optimization of different treatments and for its different needs.

Thanks to this cooperation, PROMOTION can guarantee the excellence of the raw material of its production.
