Arcobaleno - trattamento superficiale metallo

Special metal finishing:
made to measure and for every type of material

The finish is one of the last phases of the production process before the finished product is put on the market, so it requires great attention. Arcobaleno, with a view to fully satisfying every specific need of the customer to protect the metal from natural phenomena such as oxidation, prepare it for subsequent processes or give the chromatic effect as designed, provides a vast range of treatments.

Painting is an essential sheet metal process because it carries out more functions:

  • aesthetic reasons (customised colours and effects), particularly important for furnishing objects such as air conditioners, boilers, convectors, etc.
  • protective action against the natural phenomena of oxidation and deformation of materials;
  • greater performance of metals which resist atmospheric and aggressive agents and last longer over time

Below are some of the types of sheet metal painting provided

Powder coating
coating with organic film that guarantees excellent mechanical strength.
Liquid painting
brilliance and possibility to obtain any type of colour and texture on the sheet metal.
Painting on galvanised sheet metal
operation which requires technical skills to avoid, for example on steel, detachment of the paint subsequently applied.
Anti-bacterial painting
specific for several sectors such as biomedical, as it discourages the contamination of the microorganisms.
Sheet metal galvanising
Galvanising sheet metal consists of the application of a coating of zinc on metal to protect it from galvanic oxidation.

 

Sheet metal galvanising

Galvanising sheet metal consists of the application of a coating of zinc on metal to protect it from galvanic oxidation.

The types of galvanisation provided include

Hot-dip galvanising: bath of steel in molten zinc at a temperature of 450°.

Electrolytic galvanising: bath in an electrolytic solution with zinc salts that determine a coating with a thinner thickness compared to hot-dip galvanising.

Cold galvanising: similar to painting as application.

Nickel plating

Nickel bath to increase the resistance of the metal over time and avoid corrosion.

Chrome plating

Chrome bath to coat the surface with a protective patina against natural oxidation and make the part aesthetically perfect and shiny.

Screen-printing

Print on metal with special inks, resistant to time.

Cataphoresis

Process of painting that exploits the electrolytic principle to effectively increase defence against corrosion. Also cataphoresis on galvanised sheet metal.

Polishing

Elimination of any sign caused by preceding processes. The surface is mirror-like polished.
