Slightly acidic zinc is a galvanic service aimed at covering the surface of steel details with a thin coating of zinc to protect against corrosion caused by air and water. The service is carried out on a drum line and PUB 50 device. The process is based on a weak-acid bath. As part of the process, the details obtain a zinc coating with Cr + 3 white passivation with seal.

Quality features of the service:

Perfect gloss of the coating, large bath depth, about 7-12 microns thick with 40 minutes application time, very high resistance, 200 hours for white corrosion, 400 hours. to red corrosion).

Alkaline zinc is a galvanic service aimed at covering the surface of steel details with a zinc coating to protect against corrosion caused by air and water. Service provided by a suspension machine. The process is based on an alkaline bath. As part of the process, the details obtain a zinc coating with white passivation.

Quality features of the service:

perfect gloss of the coating, large bath depth, suitable for large details, resistance min. 96 hours for white corrosion and 196 hours for red corrosion.

Zn / Ni alloy zinc is a galvanic service performed in a drum technology based on a Cr + 3 alloy bath. The obtained coating is Zn / Ni alloy zinc with black or white passivation. Sealing possible with white.
