Cold-Rolled Steel Coil Precision Steel with Smooth Surface Finish

Our cold-rolled steel coils (CRC) are produced by further processing hot-rolled steel through a cold reduction process at room temperature. This results in a smoother surface finish, tighter dimensional tolerances, and improved mechanical properties compared to hot-rolled steel.

Cold-rolled coils are widely used in applications that require superior surface quality and precise shaping. They are commonly utilized in automotive components, appliances, furniture, metal packaging, and general fabrication where appearance and accuracy are important.

Key Features:

Produced through cold rolling for enhanced precision
Smooth, clean surface finish with minimal scale
Tight thickness and dimensional tolerances
Improved strength and hardness compared to hot-rolled steel
Excellent for forming, stamping, and fabrication
Suitable for automotive, appliances, and industrial applications
Available in various thicknesses, widths, and coil weights
Supplied in coil form for efficient processing and transport
Ideal for further coating, painting, or galvanizing

Product Description

Cold coil is made of hot rolled coil at room temperature and below the recrystallization temperature, including plate and coil, of which the sheet delivered is called steel plate, also known as box plate or plate; the long length and delivered in coil is called steel strip, also known as coil plate.

Production process:
Due to no heating, there are no pitting and scale defects in hot rolling. The surface quality is good and the surface finish is high. Moreover, the dimension precision of cold rolled products is high, and the properties and structure of products can meet some special requirements, such as electromagnetic properties, deep drawing properties, etc.

Performance: mainly made of low carbon steel, with good cold bending and welding performance, as well as certain stamping performance.

SPCC is commonly used cold rolled carbon steel sheet and steel strip.

SPCC Specification

Features of cold-rolled steel plate:
1, Cold rolled steel plate thickness more accurate, smooth surface, beautiful, but also has superior mechanical properties, especially machining performance.
2. The maximum thickness of cold-rolled steel plate is less than 0.1-- 8.0mm, such as the thickness of cold-rolled steel plate in most factories is less than 4.5mm;The minimum thickness and width are determined according to the equipment capacity and market demand of each plant.
3, cold rolled steel mill power, low rolling efficiency, and the rolling process in order to eliminate the work hardening have to carry out intermediate annealing, so the cost is higher, but cold rolled steel surface bright, good quality, can be used to process finished products, cold rolled steel is widely used.

65Mn CK67 high carbon cold rolled spring steel strip
Hardened and Tempered Steel Strip
Hardened and Tempered is a thermal process that strengthens steel strips through a controlled heating and cooling process. The hardening process involves heating the steel strip to above the rapidly cooling. The steel strip in this condition is extremely brittle and requires further treatment in the tempering. Then strips are reheated to a lower temperature and holding it at the given temperature for a given period of time. This process is done in an inert atmosphere to avoid oxidation. This type of steel strip has big degree of toughness and has excellent spring properties
