Heat Resistance Hot Galvanizing Plant

We are Making, Exporting and Supplying Heat Resistance Hot Galvanizing Plants in Shijiazhuang, Hebei, China. Details as given below:-

1. Application temperature range of hot galvanizing layer
Generally speaking, it is used in a wide range of temperatures. However, it should be noted that the adaptability of hot-dip galvanized structures at low temperature is determined by the adaptability of steel, not by the hot-dip galvanized layer. For example, damage to hot galvanizing at low temperature is most likely due to shrinkage of steel rather than quality problems.
In atmospheric environment, the application of hot galvanizing layer is almost unlimited.
What is the heat resistance of hot galvanizing layer? Anno answers questions
2. Upper limit of application temperature of hot galvanizing layer
Limited to 220 a or less commonly, the reason is, if the temperature is high, then there will be a zinc - the spread between Fe.
Long-term high temperature, hot dip galvanized layer of zinc - Fe for expansion of different speeds, will lead to hot dip galvanized layer falls off, can appear even steel matrix embrittlement, damaged, this phenomenon is also called "ke kendal effect".
This needs to be taken seriously in quality disputes with customers.
