Steel Grit (angular) is produced by crushing steel shot. Suitable for use in various applications as three grades of hardness are produced by different heat treatments. The GH hardness remains angular in the operating mixture (suitable for cleaning, roughening and surface finishing), the GL has the edges rounded off in the operating mixture (suitable for descaling and surface roughening prior to coating) and the GP grains become spherical (suitable for descaling work).
Steel Shot is produced by a melting process and subsequently reshaped into spherical grain particles. Due to the hardness of the new grain, high cleaning intensity is achieved from the start.
Chilled Iron Grit is produced by the melting of cast iron with the subsequent atomization and crushing of the grains. Due to the extreme hardness, the grain breaks into sharp-edged particles during the blasting process. This gives the operating mixture its permanently high cleaning and roughening properties.
