Ürün Uygulamaları
In shipyards, steel shots are widely used for surface and secondary sandblasting of hulls, ensuring effective rust removal and cleaning. They are also applied in the pretreatment lines for hull steel plates.
Section steel and plate accessories in steel structures are treated with through-type shot blasting machines, which focus on achieving the required surface cleanliness and roughness. This preparation ensures better adhesion for subsequent processes such as painting. For customers, selecting high-quality and cost-effective steel shots is essential to reduce overall production costs and minimize shot loss during sandblasting.
Rust Removal Applications: Includes shot blasting, shot peening, rust removal for castings, forgings, steel plates, H-beams, and steel structures.
Shot Blasting Applications: Applied to section steel, ship plates, steel plates, and general steel shot blasting.
Pretreatment Applications: Covers coating pretreatment, surface pretreatment, ship plate pretreatment, and steel structure pretreatment.
