Hot-dip galvanizing of steel structures in Yekaterinburg
Corrosion processes inevitably lead first to deterioration of the metal structure, and then to destruction. Therefore, steel elements must be protected from harmful effects. The most simple and budget way is to cover the details with zinc.
Hot-dip galvanizing of a metalwork in Yekaterinburg has many advantages:
- compared with similar procedures, this method is the least financially costly;
- after processing, the corrosion resistance is close to that of stainless alloys;
- increases the performance of parts;
- the high coefficient of thermal conductivity and electrical conductivity is maintained;
- the coating has the ability to self-repair-small damage overgrown at a rate of 2 mm. per year;
- there is no need to apply additional protective paint layers;
- the procedure is completely safe for humans.
The process of processing of steel structures is quite simple, but requires a fairly serious preparation.
The first step in hot – dip galvanizing of metal structures in Yekaterinburg is degreasing. Acid removes oils, synthetic formations, rust residues, scale. Additional washing of the product is required. The next stage of preparation is fluxing. The surface of the structure is treated with a special composition that performs two functions - additional sterilization and film creation. The film allows the zinc melt to better grasp the structure of the metal.
After carrying out the preparatory work, the steel part is lowered into the zinc filled with heated to 450 degrees. It is optimal to lower the product inside the rotating drum-the coating is smoother, smoother. Keep in zinc should be 3-10 minutes. Raise better, as when lowering, in the drum. The thickness of the layer depends on the lifting speed of the product. Low speed provides a thin layer of the mixture.
The final step is to remove excess zinc and dry the parts. If desired, additional protective coatings can be applied over the zinc solution, but at this stage the metal structure is completely ready for use.
The reliability of the method provided a wide application of galvanizing in various fields of production. The most popular method of corrosion protection gained in construction. It is recommended to handle any metal construction pipes, window sills, corrugated sheet. Urban construction is no exception. To protect against possible effects of the elements under the open sky, with the help of zinc treatment and drainage pipes, bridge piers, and railings of stairs. Application is not limited to construction-household utensils often require strengthening.
