Corrosion protection-galvanizing of metal lighting supports
Today, reinforced concrete lighting structures are considered obsolete. They have low ductility, which does not allow to give the product of complex architectural forms and have a unique appearance; low strength, which causes the need for regular restoration work; a lot of weight, which complicates the installation work at site.
Modern replacement of steel metal supports. They are devoid of the described shortcomings, decorate parks, estates and streets of the city, more durable and able to take almost any form. The only drawback of such structures is the high risk of corrosion, so it is mandatory for each product to be treated with a protective composition.
Application of anti-corrosion layer on supports
One of the most common methods of protection is hot-dip galvanizing of lighting poles. The process is as follows:
- The product is immersed in a solution of molten zinc at a temperature of not less than 400°C.
- Chemical interaction between metals begins by diffusion - atoms of one substance penetrate into the structure of another.
- Zinc covers the product with a smooth and dense film that protects against aggressive environmental influences.
The protective layer is classified by its thickness. Depending on the requirements, it can range from 40 to 200 µm. The greater the thickness, the stronger the resistance to external factors. Thus, a layer of 200 microns can extend the life of the product up to 30 years, without requiring special care or restoration.
The advantage of hot-dip galvanizing of lighting supports over cold in the first place is to eliminate the appearance of defects in the following stages of processing:
- preparation of the workpiece;
- treatment with detergents;
- etching of the surface;
Before processing the product is thoroughly cleaned of both fat and carbon deposits and other contaminants. The resulting material is coated with flux, which contributes to the reaction between zinc and steel. In addition to the main function — protection against corrosion, galvanizing the lighting support will give it a completely different appearance.
