Aluminium/Zinc Metallizing
Chemical-Free Surface Cleaning with High-Pressure Water
Aluminium/Zinc Metallizing is a highly effective, chemical-free surface cleaning method that uses ultra-high-pressure water jets to remove coatings, rust, marine growth, and contaminants from surfaces. It is the ideal solution for environments where abrasive contamination is not acceptable and where surface cleaning must be performed without introducing foreign materials.
What is Aluminium/Zinc Metallizing?
Aluminium/Zinc Metallizing — also known as hydro blasting — directs pressurized water at very high velocities against a surface to strip away deteriorated coatings, rust, scale, and biological fouling. The process can be performed at varying pressure levels: low pressure (LP), high pressure (HP), and ultra-high pressure (UHP), depending on the condition of the surface and the cleaning requirement.
Key Benefits
- No abrasive media — eliminates contamination of surrounding environment
- Ideal for surfaces sensitive to abrasive blasting
- Effective removal of soluble salts and chlorides from metal surfaces
- Can be performed on live plant equipment in many cases
- Environmentally friendly — uses only water
- Suitable for confined spaces and sensitive industrial areas
Applications
- Ship hull cleaning and maintenance
- Removal of old coatings from process vessels and tanks
- Concrete surface cleaning and preparation
- Heat exchangers and condenser tube cleaning
- Industrial plant shutdown maintenance
Pressure Levels
- Low Pressure (LP): Up to 5,000 psi — general cleaning
- High Pressure (HP): 5,000–10,000 psi — coating removal
- Ultra High Pressure (UHP): 10,000–40,000 psi — bare metal preparation
