Generally speaking, the occurrence of white rust on galvanized steel sheets is caused by transportation or storage. This is because the formation of white rust means that the steel coils have been exposed to high humidity and have been soaked. Sometimes due to long-distance transportation or high temperatures, Large changes in coiled steel will cause condensation, which is also very easy to cause white rust.
To prevent white rust, let us propose:
When ordering, choose different treatments according to the application conditions: including chromic acid treatment, oiling, phosphate treatment or fingerprint-resistant treatment;
Coiled steel should be covered with a tarpaulin during transportation. No matter whether it is rainy or not, avoid being soaked in a glass of water if shipped;
Coiled steel is stored in an area with good ventilation and high terrain. If the humidity is too high, you can also consider using dryer equipment;
If condensation occurs or is wetted by water, unpack it and dry it as soon as possible; for the white rust that has formed, you can wipe it off with a cloth soaked in hydrochloric acid, then rinse with cold water and dry it;
Follow the rules of first come, first added, and use as early as possible to avoid long-term storage of coiled steel;
As for GNEE galvanized sheet, it has its own characteristics when it is used, so naturally it will be used in many areas now. Then when it is used, it all has its own characteristics. What? The first aspect is its anti-corrosion performance, because for metal materials, when it is used by itself, it will cause certain corrosion performance, and also because In this way, when some products are used by themselves, their service life will be greatly reduced.
Therefore, since galvanized steel sheets have great anti-corrosion properties, nature will allow them to perform very well in their service life when they are used. There is one aspect, that is, when they are used by themselves, Sometimes, it will have its own very good beauty performance. Nowadays, when more users use it, it is also because it has its own very good advantages in its own beauty. Of course, because it has its own solution on the surface, nature will allow it to have its own advantages in appearance.
In the end, for the use of galvanized steel sheet, its price has been greatly reduced. Although there are now certain types of anti-corrosion coatings for metal materials, when it is used by itself, due to the improvement in raw materials, Therefore, nature will allow it to achieve a larger price increase on its own products when it is used by itself. When users use the product themselves, the most important point is that it will increase on their own price. It is reduced, and it only deals with the surface, so it can also achieve a big reduction in its own price.
