GP steel grit: This type of steel grit has a sharp-edged shape when it is newly made. During use, the edges and corners of the steel grit will gradually be rounded, so this type of steel grit is especially suitable for steel surfaces. Pretreatment work to remove scale.
GL steel grit: The hardness of this type of steel grit is higher than that of GP steel grit, but in the sandblasting operation, the edges and corners will gradually lose with the grinding consumption. This type of steel grit is more suitable for the removal of oxide scale on the steel surface. Operation.
GH steel grit: Compared with the first two kinds of steel grit, the hardness of this type of steel grit is higher, it can always keep the edges and corners in the sandblasting operation, so it is especially effective for forming regular and hairy surface treatment. In general, GH steel grit is often used in shot blasting machines.
