Metallizing or Thermal Spray Coating is the process of applying a thin metallic coating to a substrate for the purpose of protecting it against corrosion and physical wear using Aluminum, Zinc or their Alloys. These are heated either electronically or using a flame and are then sprayed onto a cleaned substrate. Thermal spray coatings are often applied to Bridges, Piers, and other onshore and offshore facilities.

Metallizing or Thermal Spray Coating is environmentally friendly as no potentially harmful volatile organic compounds (VOCs) are emitted. An added benefit of containing no solvents, metallizing process has virtually no cure time. Assets can be put back in service as soon as the Spraying is complete. Metallizing or Thermal Spray Coating can be applied in any temperature or level of humidity which is a boon in many situations.
