Black strip is mainly used for further pressuring, stamping, deep processing of large deformation,
as an intermediate stage of strip processing, has been widely used.
B).Bright steel strip
It need to do bright treatment on the base of black strip,can be directly made into end product after
C).Cold rolled steel strip
Usually with thickness in 0.1-3.0mm, raw material is hot-rolled steel strip or sheet,by cold rolling
under the condition of normal temperature.It with smooth and bright surface,
high dimensional accuracy,produce efficiency and convenient for subsequent processing,
so widely used.
A. Low processing cost: the cost of galvanized anti-rust coating is much cheaper than other
B. Durable: standard hot galvanized antirust coat can maintain for 20 years at least without
C.Good reliability: galvanized layer and steel is metallurgical combination, it integrates part
of the steel surface, so that the durability is more reliable
D.strong toughness:galvanized layer form a special metallurgical structure, can withstand
mechanical damage caused by transport and use.
E.Comprehensive protection: any part can be coated with zinc, even in the depression,
sharp corners and hidden place can be fully protected
F.More efficient:galvanizing process is more efficient than other coating construction method,
aslo can save brushing time required installing.
G.Inspection is simple and convenient: hot dip zinc layer can be visual and testing by
non-destructive coating thickness table easily.
