What is galvanization?
Galvanizing is the process of applying a protective layer of zinc or zinc alloys to a steel or iron surface to prevent corrosion. The most common method is hot dip galvanizing in which parts or structures are dipped in a bath of molten zinc.
Galvanizing protects steel in two different ways:
- Forms a corrosion-resistant coating that prevents corrosion of the metal substrate;
- Zinc is used as a sacrificial anode so that if the surface is damaged and the steel is exposed, it is still protected by the remaining zinc which corrodes, keeping the steel intact.
Cold galvanizing emerges as the best alternative for carrying out repairs to protect these surfaces or for a new galvanizing of whole parts, as in the case of gates, among others.
What is cold galvanizing and what are the advantages?
Cold galvanizing has the same galvanic protection factors as hot/hot galvanizing and electrolytic galvanizing.
THE ADVANTAGES OF COLD GALVANIZING:
- It can be applied in the same place where the metallic structures are located. Thus, there are no expenses with dismantling parts for a galvanizing bath. There will also be no costs with transport and new assembly of the structure.
- Its application works as if it were a painting process, using a brush or the jet of an aerosol can.
- It does not require specialized labor.
- It occurs through an electrochemical process (chemical and with exchange of electrons), that is, it does not require either heat or electrical energy.
- The high cost that conventional galvanizing companies have, such as energy to carry out the hot or electrolytic process, does not enter into the operation.
Cold galvanizing with DARKZ98 and LIGHT ZINC can be used on different types of iron and steel structures:
- weld retouching;
- restoration or galvanizing of sheet metal;
- galvanization and protection of screws exposed to the weather for long periods;
- restoration of zinc film on gates, doors, sheets, tanks and metallic structures, among others.
