Have you heard about the galvanizing process?
At Serviacero ORBIS we manufacture racks with a galvanized finish, we offer different types of galvanizing, depending on the characteristics and finishes that our customers require. The galvanizing process is a technique that has been used to protect steel from corrosion for more than 250 years. Corrosion is caused by an inherent tendency of metals when subjected to air and moisture to return to their original earthly form, usually a mineral state. They do this through a chemical or electrochemical reaction with the environment.
Galvanizing consists of coating steel parts with zinc to protect them from corrosion and enhance their mechanical strength against blows and abrasion. The galvanizing process can be hot, electrolytic by immersion or by fire. Galvanizing by immersion consists of introducing steel parts in molten zinc, at an approximate temperature of 450°C until a coating of 7-42 microns or 45-200 microns is achieved as required. By metallurgically alloying zinc with steel, a layer is created that has great adherence, is very resistant to shock and is very hard, especially suitable for use outdoors and in humid or corrosive environments. This last characteristic makes galvanized in the perfect finish for racks in constant contact with humidity, such as in the agro-industrial or food industry.
What are the advantages of this process?
The Spanish Technical Association for Galvanizing (ATEG) cites few benefits of the galvanizing process:
1. High durability
2. Zero cost of maintenance
3. Excellent cost-benefit ratio
4. Great versatility: The galvanizing process can be applied to all types of metal structures
5. High reliability: Galvanizing processes are regulated by national and international regulations, which means that they are fully controlled and certifiable.
At Serviacero ORBIS we offer all types of galvanizing, however the most used in the industry are:
By hot immersion: This type of galvanizing is the process of immersing fabricated steel or iron in a boiler or bath of molten zinc.
Electrolytic: The zinc plating process, or electrogalvanizing, is a process in which a layer of zinc is adhered to the steel through an electrostatic process in order to protect it against corrosion.
Cold immersion: This is accomplished by applying zinc-rich paints. It is generally used to make repairs to cuts or burns, but it is also used for coating steel, as well as the previous two.
