Steel Grit is made by crushing the fully hardened shot, screening the resulting media and tempering it to a desired hardness. Grit works best in tumblast applications where the eccentric rebound aids coverage. It is used in conting and/or rust removal where speed of cleaning is critical and somewhat rough finish is acceptable.
About GP / GL / GH steel grit
Made products with angular, the grit are gradually rounded off in use and its particularly suited for oxide skin pretreatment.
Harder than GP steel grit, also loses its sharp edges during shot basting and is particularly suited to surface preparation applications.
High hardness, sharp edges remain during operation, mainly used for compressed air shot blasting equipment.
