Description

We provide all specification of bearing steel grit, steel grit, steel shot, stainless steel shot, steel cut wirt shot and stainless steel cut wire shot, and can customize products according to your requirements. Welcome consulting.

The cleanliness of the metal surface after steel grit blasting treatment can meet international standards. The surface roughness reaches 25-150um, which increases the contact surface of the metal surface and improves the surface adhesion of the coating. It has significant economic benefits for refining the metal surface and strengthening the metal structure. Steel grit is the most advanced and ideal high-quality material for cleaning, spraying, rust removal, and strengthening both domestically and internationally. It is widely used in fields such as metallurgy, construction, shipbuilding, and mechanical manufacturing.
