Bare Cromate din Otel
 
Suprafata cromata dur confera  rezistenta la coroziune si uzura, reduce frictiunea, imbunatateste durabilitatea si prin rugozitate fina asigura o buna lubrifiere.
Aceste bare sunt in general folosite pentru aplicatii in medii interioare (de exemplu tije care nu sunt expuse la socuri si solicitari mecanice).
O pregatire minutioasa a materialelor inainte de acoperirea metalica ofera un aspect fin al suprafetei cromate.
