Product Application
Surface sandblasting and secondary surface sandblasting of hull in shipyard, rust removal cleaning, as well as sandblasting and rust removal cleaning of the pretreatment line of production of hull steel plate.
The section steel and steel plate accessories used in the steel structure are sandblasted and rust removed by the through shot blasting machine. Only suitable for the workpiece surface requirements of cleanliness and roughness, is conducive to the next process of painting etc. Therefore, for customers, we have to use high-quality and cost-effective steel shots to minimize production costs and reduce the loss of steel shots in sandblasting.

Frequently Asked Questions
QWhat sizes of steel grit do you offer?
We offer a wide range of steel grit sizes to suit different industrial requirements, including G12, G14, G16, G18, G20, G25, G40, G50, G80, and G120.
QWhat are the hardness types of your steel grit?
Our steel grit is categorized into three types based on hardness: GP (40-50 HRC) for general cleaning, GL (50-60 HRC) which loses its sharp edges during use, and GH (60-66 HRC) which maintains its sharp shape for maximum blasting efficiency.
QWhat are the main applications of steel grit?
Steel grit is widely used for surface sandblasting, rust removal, shot blasting, and coating pretreatment on ship hulls, steel structures, forgings, and steel plates to enhance coating adhesion.
QWhat is the chemical composition of your steel grit?
Our steel grit consists of Carbon (C: 0.85-1.20%), Manganese (Mn: 0.60-1.20%), Silicon (Si: 0.40-1.20%), Sulfur (S: ≤0.05%), and Phosphorus (P: ≤0.05%).
QWhat is the minimum density of the steel grit?
The minimum density of our steel grit is 7.4g/cm³, which can be determined by the alcoholic displacement method.
