Steel Pretreatment

Application: Before ship construction, clean rust, scale, oil stains, etc. on the surface of steel.

Functions: Eliminate surface defects to ensure the quality of subsequent cutting and welding; improve coating adhesion to extend the anti-corrosion life of the ship hull; comply with shipbuilding industry standards (e.g., ISO 8501-1 Sa2.5 level).

Surface Cleaning

Weld cleaning: Remove welding slag and burrs after welding to make the surface smooth.

Section derusting: Perform overall shot blasting on hull sections (such as decks, bulkheads) to reduce manual grinding costs.

Edge treatment: Strengthen the edges of cut steel plates to reduce stress concentration.

Anti-Corrosion Treatment

Ballast tanks and oil tanks: After shot blasting for rust removal, anti-corrosion coatings are applied to prevent seawater corrosion.

Cargo holds and pump rooms: Surfaces are treated to accommodate special coatings (such as wear-resistant and anti-slip coatings).

Surface Strengthening

Anchor chains and mooring equipment: Shot blasting strengthens the surface to improve fatigue resistance.

Pipes and valves: After pretreatment, anti-corrosion coating is applied to adapt to the harsh marine environment.

Deck machinery: Clean and strengthen components such as gears and bearings to extend their service life.
