Technical Analysis
Our metallizing services in Navi Mumbai provide sacrificial protection for steel in marine environments. By applying a thermal spray of Zinc or Aluminium, we extend the asset life of bridges and towers by decades.
1. Angular White-Metal Prep
Achieving Sa 3.0 (SSPC-SP5) with a mandatory 75-100μm angular profile. This ensures the maximum mechanical bond for the molten wire particles.
2. Thermal Spray Wire Selection
Utilization of 99.9% pure Zinc (TSZ) or Aluminium (TSA) wire based on corrosion environment. High-purity wire is critical for sacrificial protection.
3. Arc/Flame Spray Execution
Precision application of molten metal coating with zero substrate heating (no warp). Ensures cathodic protection against saline and industrial fallout.
4. Adhesion & Seal Coat Audit
Mandatory adhesion pull-off testing (ASTM D4541) followed by high-penetration seal coat application to eliminate micro-porosity.
