The zinc layer obtained by electroplating is relatively pure, and corrodes slowly in the mist of acid and alkali, and can effectively maintain the steel substrate;

The zinc coating is thick, with detailed, uniform and non-porous crystals, and good corrosion resistance;Because the zinc coating has good ductility, it can be formed by cold punching, rolling, bending, etc. without damaging the coating.

Advantages of Pre Galvanizde Steel Pipe

1. The zinc coating is thick, with detailed, uniform and non-porous crystals, and excellent corrosion resistance;

2. The zinc layer obtained by electroplating is relatively pure, and corrodes slowly in the mist of acid, alkali, etc., and can effectively maintain the steel substrate;


3. Because the zinc coating has excellent ductility, it can be cold punched, rolled, bent and other forming without damaging the coating.


4. The zinc coating is passivated by chromic acid to form white, colorful, military green, etc., beautiful and generous, with a certain decorative nature;


5. A thick and dense pure zinc layer covers the surface of the steel, which can prevent the steel substrate from touching any corrosive solution and protect the steel substrate from corrosion. In the general atmosphere, the surface of the zinc layer constitutes a very thin and dense zinc oxide layer surface, which is difficult to dissolve in water, so it has a certain maintenance effect on the steel substrate. If zinc oxide and other components in the atmosphere form insoluble zinc salts, the anti-corrosion effect is more promising.


6. It has an iron-zinc alloy layer, which is compact and exhibits unique corrosion resistance in the marine salt spray atmosphere and industrial atmosphere;


7. Because of the strong bond, zinc and iron are mutually soluble and have strong wear resistance;


8. After hot-dip galvanizing steel structural parts, it is equivalent to one annealing treatment, which can effectively improve the mechanical function of the steel substrate, eliminate the stress during forming and welding of steel parts, and is beneficial to turning steel structural parts.


9. Because zinc has excellent ductility and its alloy layer adheres firmly to the steel base, hot-dipped parts can be formed by cold punching, rolling, drawing, bending, etc. without damaging the coating;


10. The surface of the parts after hot-dip galvanizing is bright and beautiful.


11. The pure zinc layer is a layer of galvanized layer that imparts plasticity in hot-dip galvanizing. Its properties are basically close to pure zinc and have ductility, so it is rich in flexibility.
