An innovative overview of what galvanic consists of

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.

Advantages of galvanic treatments

Galvanic treatments, applied through electroplating processes, provide clear and measurable benefits:

  • Long-lasting corrosion protection, even in humid, marine, or chemically aggressive environments
  • Increased surface hardness and mechanical strength
  • Uniform and high-quality aesthetic finish
  • Excellent adhesion for subsequent surface treatments
  • Full repeatability, traceability, and industrial-grade quality control
  • Compatibility with tight tolerances and complex part geometries

All treatments are performed on automated processing lines with continuous monitoring of key process parameters to ensure full compliance with REACH regulations and ISO standards.

Electroless nickel plating (chemical surface treatment)

Electroless nickel plating is a non-galvanic surface treatment based on an autocatalytic chemical reaction. It allows for a uniform metal coating even on internal surfaces or complex geometries, without the use of electrical current.
This treatment ensures excellent corrosion resistance, surface hardness, and strong adhesion.
Gaser Group performs electroless nickel plating with different phosphorus contents, tailored to specific application needs and regulatory standards in the food, medical, technical, and mechanical sectors.
Compatible with steel, copper alloys, and aluminum, this treatment is performed in certified and digitalized processing lines to guarantee controlled thickness and customized cycles.

Electroplating process and dedicated processing lines

The electroplating process is performed in electrolytic tanks, where pre-treated parts are processed through a controlled sequence of immersion, electrical current, and mechanical movement.
Gaser Group manages the process through automated and robotic galvanic systems, ensuring continuous monitoring, repeatability, and full traceability of each production cycle.
Electroplating plants are located across several Italian sites and are capable of handling large volumes, special batches, and technical components with precise dimensional requirements.
Each plant is equipped with emission control systems, water recycling technologies, and environmental monitoring, in line with the Group's sustainability goals.

Industrial applications of galvanic surface treatments

Galvanic and electroplated coatings are applied across a wide range of industries and components:

  • Automotive and industrial vehicles: fasteners, brackets, supports, engine components
  • Aerospace: lightweight and durable structural parts
  • Precision mechanics: moving parts and mechanical couplings
  • Home appliances and electronics: electrical contacts, casings, small components
  • Food and medical sectors: metal surfaces suitable for contact with food or sterile fluids
  • Construction and infrastructure: metal frameworks, profiles, and structural frames
