Product Description
Galvanized steel tubes are divided into cold galvanized steel tubes
and hot galvanized steel tubes. Cold galvanized steel tubes have
been banned, and the latter is also advocated for temporary use by
the state. In the 1960s and 1970s, developed countries began to
develop new types of tubes, and gradually banned galvanized tubes.
China's Ministry of construction and other four ministries and
commissions have also been civilized. Since 2000, galvanized tubes
have been banned as the water supply pipes. The cold water pipes in
new residential areas have rarely been used for galvanized tubes.
Some hot water tubes used in some districts are galvanized tubes.
Hot-dip galvanized steel tube is widely used in fire fighting,
electric power and expressway.
