  The 
              main material used by Metrocast Italiana is steel.
 To 
              list every possible denomination or standards is virtually impossible, 
              due to the large quantities of commercial names, italian standards, 
              european, american, japanese and so on. For 
              this reason, here following may be found a short list showing only 
              some examples for the different kind of steel. Correspondence 
              between the different standards is approximate.   |
