Hot-dip galvanizing of trays
To protect cable systems from moisture, they are insulated with metal trays. To give the trays high anti-corrosion performance often use hot dip galvanizing trays. This makes them resistant to both moisture and mechanical damage.
Hot-dip galvanizing is a simple, reliable and cost-effective way to give the metal anti-corrosion properties. This method consists in the fact that the products, the surface of which is prepared in a special way, are lowered into a bath with molten zinc. As a result, a thin layer of zinc is formed on the surface, which protects the metal from corrosion. Advantages of hot dip galvanizing method:
- Zinc coating is able to self-repair after minor damage;
- High thermal and electrical conductivity is maintained;
- Cost-effective price;
- The possibility of further staining.
Since the trays are used for laying networks that operate under high voltage in special conditions, the zinc layer on them should be especially thick, up to 1 mm. the result is a layer that will withstand almost any test. Also hot-dip galvanizing trays allows you to use them even when installing systems that are on the street. Even in climates with high humidity, galvanized trays will last at least 50 years.
