Garnet sand blasting
Although there are many kinds of abrasives for sandblasting and rust removal, garnet sand is a cost-effective sandblasting abrasive in terms of effect and price. In terms of effect, it can reach metal blasting grades SA2.5-SA3. In terms of price, it is much lower than artificial abrasives such as brown corundum. Therefore, now the hull, carbon steel, stainless steel, castings and other polishing and rust removal and surface pretreatment are more and more widely used.
