Galvanizing stell corner
Steel corners have found their application in various construction fields, as well as in the manufacture of various metal products. Their main feature is the same thickness around the perimeter. These elements are often used to create:
- support supports;
- fences and spatial lattice structures;
- production site;
- metal furniture, etc.
Many of them are used in aggressive conditions, and therefore they need additional corrosion protection. Today, during the production of corners are galvanizing. This is a progressive and the most effective method of protection of metal structures from corrosion. The steel will be completely protected from the negative impact of the environment. Zinc has unique viscous properties that protect the surface from chipping. As a result, the service life of such structures is increased to 50 years.
Types of galvanizing corners
To date, several ways have been invented. The choice of a method is directly related to the shape of the product, its size and thickness of the formed layer. Further operating conditions should also be assessed. Galvanizing of metal is carried out by such methods:
The area of hot dip galvanizing from 78000 rubles/ton
The method of hot-dip galvanizing is considered to be the most relevant in the production and it is used by the company "EZI". The protective layer is formed by dipping the corner into the bath with molten zinc. To perform this procedure requires GOST 9.307-89. Corner 50x50x5 the most running position on the market for the galvanizing process.
The method comprises applying a composition on the basis of zinc on the precleaned surface. The method is similar to conventional painting. By means of cold galvanizing it is possible to process any details and under any conditions.
Thermodiffusion method is applied to cover a variety of thicknesses. During processing, the metal is immersed in a special container. Zinc is applied by thermal diffusion. In this method, there are certain restrictions and they are more related to the size of the corners. The container will not be able to accommodate structures of large length.
