The biggest difference with the black annealed is that the heating is not in contact with
air, with nitrogen and other inert gas has been protected, the surface color remains the same as the cold-rolled strip, in
addition to black annealed use is also used for surface tin plating and other surface treatment, beautiful and elegant.

Product Description
CRC /COLD ROLLED COIl
Often used in the steel industry, as opposed to hot rolled coil. It refers to the steel strip which is rolled into a certain thickness directly by a roller and rolled into a whole roll by a winder at room temperature. Compared with hot rolled coil, cold rolled coil surface bright, high finish, but will produce more internal stress, often annealing treatment after cold rolling.
Because there is no heating in the production process, there are no defects such as pitting and oxide sheet which often appear in hot rolling, and the surface quality is good and the finish is high. Moreover, the dimensional precision of cold-rolled products is high, and the properties and organization of the products can meet some special requirements, such as electromagnetic properties, deep drawing properties and so on.

Multiple processing equipment, good raw materials and mature cutting technology, the product cutting surface is smooth and
burr-free, the whole beautiful and solid.
NO DEFORMATION
Reliable materials, stable performance support large bearing capacity, not easy to deform and long service life.
Provide a variety of models and specifications, can be customized. Large inventory, good price and timely delivery.
Cold rolled steel advantage
Cold-rolled steel is further rolled thin to a target thickness at room temperature.
2. It is possible to obtain extremely thin strips that cannot be produced by hot rolling (up to 0.001 mm or less).
3.The surface quality of cold-rolled products is superior, there are no defects such as pitting, hot-pressed iron oxide, etc.,which are often found in hot-rolled coils, and coils of different surface roughness (glossy or hemp) can be produced according to user requirements. Rough surface, etc., to facilitate the processing of the next process.
4.The cold rolled plate has a good mechanical properties and process properties (such as higher strength, lower yield limit, good deep drawability, etc.).
5.High-speed rolling and full-continuous rolling can be realized with high productivity.
Compared with hot rolled steel:
Cold rolled steel is more accurate in thickness and has a smooth, beautiful surface, as well as various superior mechanical
properties, especially in terms of processing properties.
properties, especially in terms of processing properties.
Because cold rolled coils are brittle and hard,
they are not suitable for processing, so they are usually required to undergo annealing, pickling and surface flattening before
they are put into circulation in the market.

Bright Annealed
Black Annealed
Cold rolled strip heated directly to annealing
temperature, the surface color becomes black due to high temperature exposure to air. The physical properties become softer and
are generally used for deep processing of steel strips for re-stretching, stamping and larger deformation.

Cold rolled production line
Cold rolling steel production line adopts the most advanced cold rolling equipments and
automatic thickness control system in China. Bright cold rolled steel and black cold rolled steel are available to producing with its urface oil-coated.

Slitting and cutting
The cold-rolled coil products are accurate in
size, uniform in thickness, and the thickness difference of the coils generally does not exceed 0.1- 1.2 mm or less, which can
meet the requirements of high-precision tolerances.
The surface quality of cold-rolled products is superior, there are no defects such as pitting, hot-pressed iron oxide.which are often found in hot-rolled coils, and coils of different surface roughness (glossy or hemp) can be produced according to user requirements.
