What Is Cold Rolled Steel ?
Cold rolled steel is produced by cold rolling. Cold rolling is a steel plate that further thins the No.1 steel plate to a target thickness at room temperature. Compared with hot-rolled steel sheet, cold-rolled steel sheet is more precise in thickness, smooth and beautiful in surface, and has a variety of superior mechanical properties, especially in processing performance.
It is mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commerce. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grilles, etc. The light industry uses them to make household appliances shell, civil chimneys, kitchen appliances, etc. The automotive industry is mainly used to manufacture corrosion-resistant parts of cars, etc. Agriculture, animal husbandry and fisheries are mainly used for food storage and transportation, meat and aquatic products freezing processing equipment, and commerce is mainly used as material storage. Transportation, packaging, etc.
Full Hard Astm Cold Rolled Coil Specifications

1.The cold-rolled coil products are accurate in size, uniform in thickness, and the thickness difference of the coils generally does not exceed 0.01-0.03 mm or less, which can meet the requirements of high-precision tolerances.
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.
