Steel Grit Sandblasting takes traditional sandblasting, using air to forcibly shoot sand onto a substrate to clean it and prepare it for coating, and improves it in every way. Instead of sand, Steel Grit is used. This provides a more consistent anchor profile, cleans the substrate better and faster, and does all this without having the dust or HSE concerns of traditional sand. Best of all, the steel grit is filtered and recycled for dozens of uses!
