Normal zinc flower (small zinc flower, large zinc flower, no zinc flower) hot-dip galvanized steel plate is a kind of plating plate with obvious zinc flower shape formed by free growth of zinc grains in the normal solidification process after hot-dip
galvanized steel plate with antimony or lead in the zinc solution. The normal hot-dip galvanized steel plate is mainly used in the exposed way. The galvanized plate with zinc flowers and the galvanized plate without zinc flowers are only different
in appearance and quality.
Therefore, small zinc flower, large zinc flower and no zinc flower) the purpose of hot-dip galvanized steel plate is the same.
1、 Zinc free hot dip galvanized steel sheet
When zinc layer is solidified, there is no formation of zinc flower.
The grain is very fine and smooth, so it is called non zinc flower product. It has excellent corrosion resistance and good coating performance.
2、 Large zinc flower hot galvanized steel plate
In the zinc bath, the element of zinc flower is
added to promote the formation of beautiful zinc flower when the coating solidifies. In the early stage of use, the appearance performance is good, but the grains are coarse and there are fine unevenness
3、 Small zinc flower hot-dip galvanized steel
There is no strict definition of small zinc flower products. Generally, small zinc flower products are called small zinc flower products. In order to overcome the defects of poor coating performance of large zinc flower products, various methods
are used to inhibit the growth of zinc flower during cooling, and it is best to form zinc flower with small diameter. Because it is not as smooth as the mirror surface of the big zinc flower, nor as smooth as the non zinc flower products, so the coating
performance is very good.
