Galvanizing is a popular method to protect metal products from destruction. With it, you can extend the life of parts made of black metal. This does not require additional maintenance. The metal structure will become not only strong, but also reliable in service.
Our company carries out galvanizing of a grid according to all requirements. A small layer of zinc is applied to the surface, which is able to protect the metal from mechanical action. Zinc layer has good thermal and electrical conductivity. The created layer thickness is achieved from 40 µm to 200 µm. If the grid has to be used in special conditions, the protective coating can reach 200 microns. After hot-dip galvanizing is issued a certificate of quality, which is confirmed by compliance with all standards according to GOST 9.307-89.
In case of operation under aggressive conditions, 2 µm of zinc is lost from the protective layer. With a thickness of up to 100 microns, the product will last up to 50 years.
Galvanizing nets is the best method to protect the product from corrosion, mechanical and chemical effects of external factors. The whole process consists in immersing the parts in special baths with reagents. The main stages include:
- degreasing with phosphoric acid is carried out at a temperature of 40°C to + 45°C;
- etching consists in immersion in a salt solution with a temperature up to 15°C, and then in inhibitors;
- rinsing with process water;
- fluxing at temperatures up to + 60°C in zinc chloride;
- drying in a special chamber at high temperature;
- galvanizing by lowering the parts in molten zinc.
The company "EZI" provides all stages of processing on specialized equipment.
Why is galvanizing a popular method of metal processing?
Our company has long been engaged in the processing of metal products specially prepared solution. The formed layer has good strength. Its thickness can be different and depends on the length of stay in the bathroom. The larger the layer, the longer the product will serve. Zinc penetrates all cracks, creating a uniform and durable coating. In addition, the cost of such work is not so high.
