People adopt the hot galvanization techniques to make the galvanized steel sheets. It is a good way to prevent the metal antisepsis. People put the steel, which have removed the rust, into the zinc liquid above 500 degrees. This methods makes the steel components' surface have a zinc layer which could prevent errosion. The technicist in Bangjia will introduce the adhesiveness demand of hot galvanized sheets during the operation process briefly.

1. The hot dip galvanized coating should have enough adhesiveness to keep the plating articles from bumping during carrying, loading and unloading, transporting, installing process. The zinc coating will not be crazed or avulsed. When people finish the installation, it will not came across the bump. Therefore, it will not avulse and fall off during the use procedure.

2. The galvanized parts adopt the low-silicon steel, the plating thickness is moderate. The alloy zinc is a little thin but the zinc layers is too thick. It could bear the hammering test. The iron alloy zinc is very thick, sometimes , it is the main part of the whole cladding material. Some parts may not pass the hammering test, but it does not have the quality problem.
