Guyson Flexgrain is a specially produced soft iron bead with exceptional cleaning properties. The shot multiplies its effectiveness during blasting, due to the ricochet effect. The non-aggressive nature of the product allows Flexgrain to be used for gentle removal of surface deposits, without damage to sensitive substrates. Flexgrain would generally be used in wheel/turbine or pressure feed blast systems, but is still effective when used in suction feed systems.
