Cold rolled thin steel plate is the abbreviation for cold rolled sheet of ordinary carbon structural steel, also known as cold rolled plate, commonly known as cold plate, sometimes misspelled as cold rolled plate. Cold plate is made from ordinary carbon structural steel hot rolled steel strip, after further cold rolling made of steel plate with a thickness of less than 4mm. Due to rolling at room temperature, does not produce iron oxide, therefore, the cold plate surface quality, high dimensional accuracy, coupled with annealing, its mechanical properties and process properties are better than hot-rolled sheet, in many areas, especially in the field of home appliance manufacturing, it has been gradually used to replace the hot-rolled sheet.
Applicable grades: Q195, Q215, Q235, Q275; SPCC (Japan); ST12 (Germany)
Symbols:
1, Q - ordinary carbon structural steel yield point (limit) of the code, it is the first Hanyu Pinyin of the "yield", the "yield" of the first carbon structural steel. "The first Chinese Pinyin letters of the case; 195, 215, 235, 255, 275 - were expressed in their yield point (limit) of the value, unit: MPa (N / mm2); due to the strength, plasticity, toughness and weldability of the Q235 steel and other comprehensive mechanical properties in the ordinary carbon structural steel is the best, can better meet the general carbon structural steel, and can also be used for the production of steel. The best, can better meet the general requirements of use, so the scope of application is very wide.
2, S - steel (Steel), P - plate (Plate), C - cold rolled (cold), the fourth C - common grade (mon).
3, ST-Steel (Steel), 12-ordinary cold rolled thin steel plate,

Question 2: What is the material of SPCC? What material? Japan Cold Rolled Carbon Thin Steel Sheet Bean Applicable grades: SPCC, SPCD, SPCE Symbols: S-Steel (Steel), P-Plate (Plate), C-Cold Rolled (cold), the fourth C-ordinary grade (mon), D-stamping grade (Draw), E-deep-drawn grade (Elongation)
Equivalent to China Q195-215A The grade is equivalent to China's Q195-215A.
Question 3: What is SPCF material? SPCF is a kind of cold rolled steel, usually used in the manufacture of cold rolled steel plate, it is a low carbon steel grade, this kind of steel is required to have valve good cold bending and welding properties, as well as certain stamping properties. Cold rolled plate production process as a result of not heating, so there is no hot rolled often appear pitting and iron oxide and other defects, good surface quality, high finish. And cold rolled products of high dimensional accuracy, product performance and organization to meet some special requirements for use, the use of a wide range of applications, such as automotive manufacturing, electrical products, rolling stock and so on!

Question six: What is cold rolled plate spraying? First of all, cold rolled steel plate:
Cold rolled steel plate is cold rolled steel production, commonly known as cold plate. Cold rolled is a steel plate at room temperature conditions will be further rolled thin to the target thickness of the steel plate. Compared with hot rolled steel plate, cold rolled steel plate thickness is more accurate, and the surface is smooth, beautiful, but also has the superior mechanical properties of the penalties, especially in terms of processing performance. Cold rolled minimum thickness is 0.1 - 8.0MM below, the minimum thickness, width is based on the plant's equipment capacity and market demand and decide.
After the completion of the cold rolled steel production parts, the need for surface treatment, including:
1: electroplating: galvanized, nickel-plated, copper-plated, gold-plated, chrome-plated,
2: dip-plating: blackened, hot-dip galvanized
3: spraying: spray painting, plastic spraying, baking paint,
4: polishing, polishing, shot-blasting, wheelblasting
which plastic spraying is the plastic powder spraying. Is a plastic powder sprayed on the parts of a surface treatment method. Plastic spraying is also commonly referred to as electrostatic powder coating, it is the use of electrostatic generators to make plastic powder charged, adsorbed on the surface of the iron plate, and then after 180 ~ 220 ℃ baking, so that the powder melted adhesion in the metal surface, plastic spraying products are mostly used for indoor use of the box, the paint film presents a flat or matte effect. Spray powder mainly acrylic powder, polyester powder.
As for the process of plastic spraying you can use Baidu search, the answer is more detailed.
If you are looking for plastic spraying manufacturers, the general machining industrial zone will have, and even companies specializing in surface treatment.
