Galvanized Steel Coil Introduction
Cold rolled galvanized coil is a kind of galvanized steel sheet.
Steel sheets and coils are classified into hot-rolled and
cold-rolled according to rolling. Cold-rolled sheet is flat,
rectangular, and can be directly rolled.

Cold rolling is a steel coil that is further thinned to a target
thickness at room temperature. Compared with hot-rolled steel
sheet, cold-rolled steel coil has more accurate thickness, smooth
and beautiful surface, and also has various superior mechanical
properties, especially in terms of processability. Because
cold-rolled raw coils are relatively brittle and hard, and are not
suitable for processing, cold-rolled steel coils are usually
required to be annealed, pickled and surface smoothed before being
delivered to customers.
Advantages of cold rolling:
The forming speed is fast, the output is high, and the coating is
not damaged. It can be made into a variety of cross-sectional forms
to meet the needs of use conditions;
Cold rolling can produce a large plastic deformation of the steel,
thereby increasing the yield point of the steel.
The benefits of galvanizing:
1. Coated galvanized coils are very popular in adapting to various
environments and have a long anti-corrosion period, but the
anti-corrosion period is different in different environments.
2. The processing cost is low, and the anti-rust cost of galvanized
coil is lower than other paint coatings.
3. Durable and durable. In suburban environments, a standard
galvanized sheet rust coating can last for over 50 years without
maintenance. In urban or offshore areas, the standard galvanized
anti-rust layer can be maintained for 20 years without repair.
4. Good reliability, the metallurgical bond between the galvanized
layer and the steel is part of the rigid surface, so the durability
of the coating is more reliable.
5. The toughness of the coating is strong. The galvanized layer
forms a special metallurgical structure that can withstand
mechanical damage during transportation and use.
6. Overall protection, every part of the plated part can be plated
with zinc, and it can be fully protected even in depressions, sharp
corners and hidden places.
7. Save time and effort, the galvanizing process is faster than
other coating construction methods, which can avoid the time of
painting on the construction site after installation.
