1. GP steel grit: When this abrasive is newly made, it is sharp-edged, and the edges and corners are quickly rounded during use, which is especially suitable for the removal of oxide scale on the surface of steel.
2. GL steel grit: Although the hardness of this type of steel grit is higher than that of GP steel grit, it will still lose its edges and corners during the sandblasting process, which is especially suitable for the removal of oxide scale on the steel surface.
3. GH steel grit: This type of steel grit has high hardness and will always maintain edges and corners during sandblasting operations, which is especially effective for forming regular and hairy surfaces. When GH steel grit is used for shot peening operations, the occasions where construction requirements take precedence over price factors (such as roll treatment in cold rolling mills) should be considered. This steel grit is mainly used for compressed air shot blasting equipment.
