We provide galvanization in mild acidic and alcalic electrolyte. These electrolytes are in these days most popular technology of galvanizing. It provides a high gloss surface with a thin and ductile layer. GALVAN CZ s.r.o. performs galvanizing without passivation with following passivation by transparent Cr3+, optionally with additional yellow chromate Cr3+. For all types of finishes we offer sealing.
Phosphating is a coating method which creates the insoluble phosphate layer on the surface of product. The crystalline layer is electrically nonconductive and insoluble in water or organic solvents. It has very good cohesiveness with base metal and it is suitable as a subgrade layer before varnishing. Phosphating protects from corrosion if products are additionally treated with oil, wax or other way.
In cooperation with company DELTACOL CZ s.r.o., whose business premises are located within GALVAN CZ s.r.o building complex, we provide finishing by DELTACOLL varnishes. The coating is made by soaking electroplated galvanized products into the varnish. This coating provides high corrosion resistance and it is required primarily for parts used in automotive.
High pressure blasting of steel materials is part of the surface preparation for further technological operations, such as phosphate coating, varnishing or galvanizing. Blasting is used as one of the most effective methods to remove rust, paint, oxides and other impurities from the basic materials.
