Hot Dipped Galvanized Steel：
Product advantages of hot dip galvanized steel sheets:
1. The entire steel surface is protected. No matter inside the recessed pipe fitting or any other corner where the coating is difficult to enter, the molten zinc can be easily and evenly covered.
2. In the corner areas, the zinc layer is often thicker than in other places and has good toughness and wear resistance. The corners of other coatings are often the thinnest, most difficult to apply, and most vulnerable to damage, so they often need to be maintained.
3. In addition to hot dip galvanizing, there are several other methods to protect steel with a zinc layer. Generally, the most widely used method, with the best anti-corrosion effect and the best economic benefits, is the hot dipped galvanizing method.
4. Even if it suffers heavy mechanical damage or other reasons. A small part of the zinc layer will fall off, exposing the iron base. At this time, the surrounding zinc layer will function as a sacrificial anode to protect the steel here from corrosion. On the other hand, the opposite is true for other coatings. Rust will form immediately and quickly spread underneath 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 is predictable. Its lifespan is far longer than any other coating.
6. The coating life span 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, the easier it is to get a thicker coating. Therefore, the thicker steel parts in the same steel structure must also get a thicker coating to ensure a longer life.
The principle of hot dipped galvanizing is simply to immerse the cleaned iron parts into a zinc bath through the wetting effect of the plating flux, so that the steel and molten zinc react to form an alloyed film. A good hot-dip galvanizing operation should ensure that each process is under strict control and that the function of the process can be fully utilized. And if the previous process is not operated properly, it will cause a chain reaction of adverse reactions in the subsequent processes, which will greatly increase the operating cost or result in defective hot-dip galvanized products. If the pre-treatment is poor, the molten zinc cannot fully react with the steel to form the most perfect galvanized film structure. If the post-processing is poor, the appearance of the galvanized film will be damaged and the product value will be reduced.
