Surface treatments for metals are essential to improve corrosion resistance, extend the service life of industrial components, and enhance their functional performance.
Gaser Group offers a broad portfolio of galvanic and chemical surface treatment technologies designed to meet the highest technical and regulatory standards across key industrial sectors.
What are industrial galvanic treatments?
Industrial galvanic treatments, also referred to electroplating processes, are electrochemical techniques that apply a protective coating to the surface of metal components by means of controlled electrical current in electrolytic solutions.
These treatments are widely used in sectors that require high functional reliability, such as automotive, precision mechanics, electronics, and construction.
Main electroplating treatments for metals
Anodizing
Anodizing is a specific galvanic treatment for aluminum and its alloys.
Through an electrolytic process, it forms a controlled, compact hard oxide layer on the surface, significantly improving resistance to corrosion, wear, and chemical agents.
Anodizing also provides uniform and durable aesthetic finishes, including color options, ideal for exposed or visible components.
Gaser Group offers natural, semi-hard, hard, and colored anodizing, with traceable and repeatable processes, suitable even for large-scale series and complex geometries.
Zinc plating
Zinc plating is a galvanic treatment that deposits a uniform layer of zinc on the surface of steel components.
Zinc provides both barrier protection and active cathodic protection, ensuring excellent corrosion resistance even when the surface is scratched or worn.
Gaser Group operates dedicated automated systems for both acid and alkaline zinc plating, optimized for high-volume production, controlled thickness, and certified quality.
This treatment is ideal for fasteners, small metal parts, mechanical components, and structures exposed to environmental conditions.
