There are two types of galvanized steel pipes: Hot dipped galvanized steel pipes and pre galvanized steel pipes. Hot dipped
galvanized steel pipes are covered with a thick zinc coating, and have the advantages of uniform coating, strong adhesion, and
corrosion resistance, meanwhile enjoy a longer service life. Pre galvanized steel pipes have a smooth surface. It is made of
galvanized steel strips, the zinc coating is thin, only 10-50g/m2. Its anti-corrossion properties is obviously not that good as the
hot dipped galvanized ones.
Galvanized steel pipes are widely used as contruction/building materials pipes, Scaffloding pipes, Solar Structure component
pipes, Fence post pipes, Greenhouse frame pipes, etc. There is also the other type of galvanized steel pipes to be used as delivery
pipes for low pressure liquid water/gas/oil, and fire spinkler steel pipes.
