Zinc and zinc-nickel plating for the automotive industry
We protect your steel parts against rust with electroplated coatings free of hexavalent chromium. Located in the Puebla industrial corridor, next to Hermanos Serdán International Airport.
Electrogalvanizing (electroplating). We do not offer hot-dip galvanizing.
Our main processes
Select a process to see its technical sheet, typical applications and frequently asked questions.
Alkaline zinc
A cyanide-free silver coating that protects metal components from rust. Excellent metal distribution and an ideal base for parts that will later receive KTL (e-coat) paint.
View technical sheetZinc-nickel
A high-performance alloy (8% to 15% nickel) that retains its high corrosion resistance even after heat exposure, ideal for severe conditions with humidity or road salt.
View technical sheetHeavy phosphate
A non-metallic zinc and manganese phosphate coating designed specifically to retain lubricants and reduce wear between parts in contact.
View technical sheetSurface preparation
Standalone or pre-treatment processes, including vibratory finishing, rust removal and degreasing, to deliver clean, properly conditioned parts.

Over 10 years of experience
Our technical team brings at least a decade of experience in metal finishing for the automotive and industrial sectors.
Hexavalent chromium free
Our finishes contain no hexavalent chromium, one of the substances restricted under RoHS and ELV regulations due to its toxicity.
PPAP documentation
We provide the technical and quality documentation the automotive industry requires to approve suppliers and their processes.
World-class chemistry
Our plating baths are formulated with products from leading global suppliers in the industry: Atotech, Columbia Chemical, Henkel, Etnasa and Ambieter.
Meeting automotive specifications
If your part drawing calls for a specification from a global OEM such as Volkswagen, Ford, GM or Nissan, we perform in-house checks of thickness, adhesion and bath chemistry, and validate corrosion resistance through an external laboratory, according to your customer's specification.
