Grillo US Corporation Thermal Spray Solutions
The first choice for sustainable corrosion protection
What is thermal spraying?
The thermal spray process uses the most advanced in-house zinc alloys to ensure long-lasting corrosion protection and coating thicknesses with high adhesion strength. This pioneering technology is used in a variety of applications, from bridge refurbishment to industrial applications, and relies on state-of-the-art coating technologies such as arc spraying and flame spraying to ensure effective adhesion of the zinc coating. Quality controls and expert knowledge in material preparation and protection concepts contribute to sustainability and damage prevention. At GRILLO, you benefit from our unique expertise and high-quality products that are considered market leaders. As a one-stop-shop provider, we also offer comprehensive solutions, with our focus always on environmental protection and efficiency.
How long has the thermal spray process been in use?
The application of thermal metal spraying for corrosion protection of steel bridges has a long history of success. Since the 1950s, steel bridges around the world have been coated using this method. The initial projects were undertaken in the USA and the United Kingdom. In Norway, the road authority has mandated thermal metal spraying for all bridges in marine environments since the 1960s. The method has also been successfully applied to road and railway bridges in the Benelux countries since the beginning of this millennium.
In Germany, thermal metal spraying has not yet been fully integrated into the regulatory frameworks, yet projects such as the Grevenhof lock bridge demonstrate the immense potential of this proven method in the corrosion protection of steel structures.
What are common alternative technologies to thermal spraying?
As alternatives to thermal spraying, there are hot-dip galvanizing and paint coatings. In hot-dip galvanizing, the metal is immersed in molten zinc to form a protective layer. Paint coating involves applying a protective paint to the surface to guard against corrosion.
