Surface sandblasting and secondary surface preparation of ship hulls in shipyards, including rust removal, cleaning, and pretreatment line processing for hull steel plates. Haishan steel shot ensures uniform surface roughness for optimal coating adhesion.

Section steel and steel plate components used in steel structures are sandblasted and derusted using through-type shot blasting machines. This process achieves the required surface cleanliness and roughness for subsequent painting. Haishan high-quality steel shot and steel grit minimize production costs while reducing abrasive consumption during blasting.

Casting sand and oxide scale remain on the surface and internal structure of cast parts after the casting process and must be removed by shot blasting. Forgings develop an oxide layer during heat treatment as well. Due to the high hardness requirements of castings, only high-strength, high-wear-resistant steel shot or steel grit can achieve the desired blasting effect.

Containers endure prolonged ocean transport in humid, salty environments, requiring excellent paint adhesion and corrosion protection. Shot blasting of container surfaces demands strict control of surface roughness and cleanliness. Only high-quality steel shot or steel grit with good toughness can achieve the expected blasting results and extend coating service life.

Before surface painting of machinery and its components, all parts must undergo strict sandblasting and cleaning to ensure proper coating adhesion and long-term corrosion resistance.

Before final assembly, nearly all locomotive frame bodies and related components must undergo sandblasting and rust removal treatment to prepare surfaces for protective coatings.

Proper removal of the oxide layer on the outer surface of pipelines is essential to meet the quality requirements of anti-corrosion coatings. Surface roughness, cleanliness, and coating adhesion all depend on the consistent quality of steel shot and steel grit used during blasting.

Sandblasting rooms are primarily used for rust removal on large and irregularly shaped objects. Many mechanical equipment, castings, and non-standard parts cannot be cleaned by fixed shot blasting machines and require manual sandblasting. Typical applications include hull surfaces, wind power towers, large steel structures, and heavy castings.

Springs, steel plates, and similar products require high hardness and strict quality control with stringent surface preparation standards. To achieve the specified surface roughness and cleanliness, high-hardness steel shot and steel grit with secondary quenching treatment are essential.
