PLATING & CHEMICAL SURFACE TREATMENTS
Industrial Plating and Chemical Surface Treatments
Are you looking for a company offering plating and chemical surface treatments service in Quebec, Canada or United States ?
​
Fabrication doesn't end at welding. To ensure longevity and performance, metal components must be chemically treated to resist corrosion and maintain conductivity. Graphie provides a comprehensive suite of Plating and Surface Treatment solutions for steel, aluminum, and copper components.
Whether you need a sacrificial coating for outdoor steel structures or a conductive finish for electrical busbars, we deliver parts that are chemically processed and ready for installation.
Steel Protection: Zinc and Galvanization
For carbon steel components, preventing rust is the priority. We offer two distinct levels of protection depending on the environment:
-
Zinc Plating (Zinquage): The standard industrial finish for brackets, fasteners, and indoor mechanical parts. It provides a clean, bright finish and excellent corrosion resistance for standard environments.
-
Galvanization: For structural steel used outdoors or in harsh environments, we provide hot-dip galvanization services. This creates a thick, metallurgical bond that protects the steel for decades, even if the coating is scratched.
Aluminum Treatment: Chromate Conversion
Unlike anodizing which insulates the metal, Chromate Conversion (often referred to as Chemical Film or Alodine) protects aluminum from corrosion while maintaining electrical conductivity.
-
Applications: Ideal for electronics chassis, grounding points, and shielded enclosures where electrical continuity is required.
-
Paint Base: It also serves as an excellent primer, ensuring superior adhesion for powder coating or paint.
Stainless Steel Care: Passivation and Weld Cleaning
Stainless steel is corrosion-resistant only if its surface is pure. Manufacturing processes like welding and machining can introduce iron contaminants that lead to rust.
-
Passivation: We treat stainless steel parts with an acid solution that removes free iron from the surface and promotes the formation of the natural passive oxide layer, restoring its full corrosion resistance.
-
Electrochemical Weld Cleaning (Surfox): For welded stainless steel assemblies, we use the Surfox electrochemical cleaning system. This instantly removes heat tint and weld discoloration while simultaneously passivating the heat-affected zone, leaving a clean, uniform finish without the hazards of pickling paste.
Electrical Plating: Tin (Étamage)
For the energy and transport sectors, we specialize in Tin Plating (Étamage) for copper and aluminum busbars and electrical contacts.
-
Benefits: Tin plating prevents oxidation of the conductor (which increases resistance) and ensures low contact resistance at bolted joints. It also improves solderability for electronic components.
