The main purpose of surface treatment is to increase the protection against corrosion or wear on different types of parts before their final assembly and commissioning. These operations ensure that the parts concerned comply with applicable regulations and standards in the field. This represents a real advantage for MECAPROTEC Industries' customers who gain in terms of performance and lead-times.

We master all surface treatments that apply to the aeronautical sector: cadmium, phosphate, oxide, anodic, conversion and zinc-nickel coatings. Our expertise is supported by the requisite accreditations and certifications for carrying out our missions.
