Product Description
Zhengde Cold rolled steel plate is the abbreviation for ordinary
carbon structural steel cold rolled plate, also known as cold
rolled plate. Cold rolled steel plates are hot-rolled steel strips
of ordinary carbon structural steel, which are further cold rolled
to produce steel plates with a thickness of less than 4mm. Due to
the fact that rolling at room temperature does not produce oxide
scale, the cold plate has good surface quality and high dimensional
accuracy. In addition, annealing treatment results in better
mechanical and technological properties than hot-rolled thin steel
plates. In many fields, especially in the field of home appliance
manufacturing, it has gradually been used to replace hot-rolled
thin steel plates.| Usually available specification range |

Our Advantages
High precision
Cold-rolled high-quality thin steel plate: mainly includes various
high-quality steel cold-rolled thin plates, the most commonly used
is carbon structural steel plate, especially cold-rolled thin steel
plate for deep drawing, which is cold-rolled thin plate made of
low-carbon high-quality steel 08Al. The quality is divided into
three groups;1 ,2 and 3, which represent particularly high-grade,
high-grade, and higher-finish surfaces, respectively.
Extensive use
Cold-rolled steel plate with smooth surface and excellent
processing, used for home appliances such as automobiles,
refrigerators, washing machines, industrial equipment, and various
building materials. With the development of the economy,
cold-rolled steel sheets have been called necessary materials in
modern society. Classification of cold-rolled products: hot-rolled
pickling, hard-rolled coil, ordinary cold-rolled, galvanized
(electro-galvanized, anti-fingerprint, hot-dip galvanized),
galvanized, electro-tinned, color-coated, electrical steel (silicon
steel sheet) wait.
Strict craftsmanship
Cold rolled steel coils generally use hot-rolled strip steel with a
thickness of 1.5-6 mm as the cold rolled billet. The main processes
include pickling, cold rolling, degreasing, annealing, leveling,
and shearing (cross cutting, longitudinal cutting). If producing
coated plates, there are also plating or coating processes such as
electroplating tin, hot tin coating, and hot zinc coating. The
production process of cold rolled billets is as follows: hot rolled
sheet coils (raw materials) - acid washing - cold rolling -
degreasing - annealing - leveling - shearing - finished product
delivery.
Provide deep processing
The company's slitting machine, slitting line, cuts cold rolled
steel coils into strips of various widths as needed, and then folds
the strips into small coils for use in the next process. It is a
necessary equipment for precision cutting of transformers, motor
industries, and other metal strips. It is mainly used for strip
cutting of materials such as tinplate, galvanized iron, silicon
steel sheet, cold rolled strip, stainless steel strip, aluminum
strip, steel strip, and other coils.
