Saves maintenance costs by the void corrosion in a range of 20 to 50 years. In rural atmospheres this duration is generally superior to 50 years, and 20 to 25 years, or even more, in an industrial severe environment.
The high protection provided by this system, often exceeds the expected life for facilities, making it unnecessary, in most cases, the maintenance.
The range of products that can be galvanizing is very broad, in such a way that serves both for the protection of small parts such as: fittings, cast iron parts or screws, up to tubes or structural parts of large dimensions.
Because in most cases the galvanized material requires no maintenance decreases the use of paints and solvents, which reduces pollution and positively impacts the environment.
The different elements that constitute the bodies soldiers can join by the same welding methods that are normally used for the steel in black, it is necessary to adapt the surgical technique and the parameters of welding to the particular conditions of the galvanized material. Coating areas burned by effects of heat can be easily restore through paintings rich in zinc.

Iron and steel are quickly rusted, the layers of paint deteriorate over time and allow the passage of moisture, which has as a consequence the metal oxide and the deterioration of the materials. The galvanized is ideal to prevent corrosion or rust from metals.
These solutions serve to most of the soluble oils and lubricants that are used to manufacture the parts.
For most of the pieces to be treated, this is the first operation that is performed and by treatment with acids, it eliminates the husks of manufacture and rust that has formed in the workpiece.
Is intended to protect parts from oxidation, after they have been pickled coils, in addition to allow the zinc good adhesion and runoff on steel.
After cleaning, the material to be covered is immersed in a bath of molten zinc, maintaining a temperature of approximately 450° C. The thickness of the layer of zinc is proportional to the time of immersion.
This is the final step of the process, here the products are inspected to ensure the integrity of the coating, as well as the thickness of the layer is measured to verify that this is according to the rules.
In Center Galvanizer 2000 we work under:
The coating consists of a progression of layers of zinc-iron alloy, nations metallurgically bonded to the steel base.
(PAINTING VS GALVANISED)
BY HOT IMMERSION
As a protection-barrier, the galvanized provides a tenacious coating of zinc metallurgically bonded that completely covers the surface of the steel with a layer of zinc-iron alloy, which is harder than steel base. This provides a flexible outer layer with a stronger commitment and exceptional resistance to abrasion. An additional feature of the galvanized, is that the layer of zinc-iron grows perpendicularly to the surface of the steel. The effect this has on the corners edges of the materials is that the coating there is generally thicker than the lining around it. This is in marked contrast to other types of protective coatings that tend to thin in the corners and edges of the materials.
The galvanized coating is more resistant to physical deterioration that a layer of paint. The entire surface of the workpieces is covered both inwardly and outwardly. Also with the narrow slits, the corners and hidden parts of the pieces, being well protected. Even if in the lining there are small bare areas (such as scrapes) by bad management, these are protected against oxidation. This is due to the electrochemical potential difference between zinc and iron, so the first is consumed in preference to the latter and provides you with a “sacrificial or cathodic protection”. This type of protection is one of the main virtues of the coatings obtained in hot.
