1. The whole steel surface is protected, no matter in the depression, inside the pipe or any other corner where the coating is difficult to enter, the dissolved zinc is easy to cover evenly.

2. The hardness of zinc coating is higher than that of steel. The hardness of the top ETA layer is only 70 DPN, so it is easy to be concave due to collision. However, the hardness of the lower zeta layer and delta layer are 179 DPN and 211 DPN respectively, which is the highest than that of the iron 159 DPN. Therefore, the impact resistance and wear resistance are quite good.

3. In the corner area, the zinc layer is usually thicker than other places, and has good toughness and wear resistance. Other coatings are usually the thinnest, the most difficult to construct and the most vulnerable to injury at this corner, so they often need to be re maintained.

4. Even if it is caused by great mechanical injury or other reasons. At this time, the surrounding zinc layer will play the role of sacrificial anode to protect the steel from corrosion. On the other hand, the other coating is just the opposite. The rust will form immediately and spread rapidly to the bottom of the coating, causing the coating to peel off.

5. The consumption of zinc layer in the atmosphere is very slow, about 1 / 17 to 1 / 18 of the corrosion rate of steel, and it is predictable. Its life is much longer than any other coating.

6. The life of the coating depends on the thickness of the coating in a specific environment. The thickness of the coating is determined by the thickness of the steel, that is, the thicker the steel is, the thicker the coating is. Therefore, the thick steel parts of the same steel structure must also get thicker coating, so as to ensure a longer service life.

7. Because of the beauty, art, or in a specific serious corrosive environment, the zinc coating can be treated with the above paint. As long as the paint system is selected correctly and the construction is easy, the anti-corrosion effect is 1.5 ~ 2.5 times better than that of single painting and hot dip galvanizing.

8. In addition to hot-dip galvanizing, there are several other methods to protect iron and steel with zinc coating. Generally, hot-dip galvanizing is the most widely used method with the best anti-corrosion effect and economic benefit.
Hot dip galvanizing production line equipment

Standardize production process: mainly based on the processing needs of different industry fields, the application requirements of hot dip galvanized production line equipment will also be different. When practical selection, specific problems will be analyzed to ensure that the hot-dip galvanizing equipment can play a role. It is suggested that the self production line can be planned comprehensively, the processing process and requirements can be observed, and whether any equipment is needed, how can standardized and strict production and processing be formed, the operation rate can be improved, different hot dip galvanizing production line equipment matching can be made, so as to ensure smooth and stable production and processing.

Hot dip galvanizing production line equipment mainly includes many types, and there will be more differences in parameter indexes in all aspects. When choosing the equipment, we need to look at the relevant parameters of the equipment, understand its processing function and application, and see if it can meet the requirements of production standards. At the same time, according to the operation of different manufacturers, there will be many differences in the production and processing of equipment. It is necessary to know the basic conditions first, so as to ensure the smooth progress of hot dip galvanizing.
