Finished: Silver and yellow iridescent – The galvanizing process consists of a cathodic electrodeposition of metal zinc on steel metal parts. Usual deposit thickness varies between 8 µm and 20 µm. Types of finish depend on the passivation type applied: White, iridescent of high thickness White (oxide of Zinc) corrosion resistance also depends on the passivation type, and varies between 48 hours for white passivation, up to 300 hours of exposure to salt fog in high thickness iridescent passivation (NSS) according to DIN EN ISO 9227.

Zinc-Nickel Transparent, blue or black finish but sealed (optional) – The zinc – nickel plating process consists of a cathodic electrodeposit of zinc and nickel on steel metal parts. The proportion of metal alloy nickel ranges between 12% and 16%. Usual deposit thickness varies between 8 µm and 20 µm. The types of finish color depend on the type of passivation applied: gray, silver, iridescent blue or black. Resistance to white corrosion (zinc oxide) depends on the type of passivation, if any, or if not, an additional seal, varying between 144 hours for only passivated parts and up to 240 hours of exposure of sealed and passivated parts to salt fog. The corrosion resistance of the base material (red corrosion ) in general is 720 hours and with passivated and sealed parts it can reach 1,200 hours of salt fog (NSS) according to DIN EN ISO 9227.

Black finish – The cataphoresis painting process consists of a cathodic electrodeposit of epoxy paint on steel metal parts. Previously, the parts must have been degreased and phosphated with a phosphate, microcrystalline tricationic zinc, nickel and manganese. The usual deposit thickness varies between 15 µm and 30 µm, although thicknesses of up to 60 µm are possible. The finish color is black matte (RAL9005). Resistance to the corrosion of the salt mist (NSS) according to DIN in ISO 9227 is about 800 hours without corrosion of the base material. Respect to the resistance of cyclic corrosion tests, supports up to 30 cycles of corrosion according to the standard VW PV1210 parts of high thickness (30 µm – 60 µm) up to 60 cycles.

Black finish – The process of applying zinc + paint by cataphoresis consists in cathodic electrodeposit of zinc on steel parts without applying any later passivation. Usual deposit thickness varies between 8 µm and 14 µm. Once the parts have been galvanized, a coat of paint is applied by cataphoresis as described, with a thickness of 15 µm to 30 µm. This duplex coating supports 30 cycles of corrosion according to the standard PV1210 of VW. This process is widespread in the automobile sector, as well as pre-coated painted parts and components, galvanized and electrogalvanized.

Black finish – The zinc-nickel + painting process by cataphoresis consists of cathodic electrodeposit of zinc and nickel on the steel metal parts with a proportion of nickel of 12% to 16%. Usual deposit thickness varies between 8 µm and 20 µm. Once the zinc-nickel parts are coated, a layer of paint, with a thickness of 15 µm to 30 µm is applied for cataphoresis. This duplex coating supports 60 cycles of corrosion according to the standard PV1210 of VW. Recently, this coating has become widespread in the automotive industry due to its high resistance to corrosion.

Blasting is the projection of steel microshot on metal to clean or polish the surface parts and/or components. The microshot is projected up the parts or components through special turbines in a chamber destined for this use.

The degreasing consists in a treatment chemical with alkaline and surfactant degreasing products to remove oils and/or fat of the surface of the metal parts or components. This process operates on a drum processing line.

Vibration consists of a treatment by erosion of metal parts and/or components to remove burrs from the contour and other surface imperfections. The process takes place in a circular drum subjected to vibration, in which abrasive stones are in contact with the parts. The effect of the vibratory motion of the stones on parts or components is that it allows deburring and polishing them. To this process are added water, surfactant detergents, anticorrosive, antioxidant products to prevent further oxidation of parts.
