SPCC Cold Rolled Coil
SPCC was originally the name of “cold-rolled carbon steel sheets and strips for general use” in the Japanese Standard (JIS G 3141). Many countries or companies directly use it to represent similar steel products they produce. Note: Similar grades include SPCD (cold-rolled carbon steel sheets and strips for stamping), SPCE (cold-rolled carbon steel sheets and strips for deep drawing), SPCCK\SPCCCE, etc. (special steel for televisions), SPCC4D\SPCC8D, etc. (hard-rolled carbon steel sheets and strips) High-quality steel, used for bicycle rims, etc.)), used in different occasions.
What Is SPCC Steel?
SPCC is called cold-rolled steel plate and is made by cold-rolling SPHC (Steel Plate Hot Commercial). Among carbon steels, the carbon content is less than 0.1%, and it is classified as an SPCC material.
SPCC is a steel material for sheet metal and press, and only plate material is not distributed. Most of the board thickness is 0.5 to 2.5mm, and among them, board thickness of 1.6mm and 2.0mm are stable distribution.
SPCC Steel Plate:
Abbreviation for Steel Plate Cold Commercial. Steel sheet rolled at room temperature.
SPCC is also called “rolled material”, “cold”, and “polished material” because of its smooth surface.
Types of rolled steel sheets
| hot rolled steel plate | cold-rolled steel plate | ||||
| SPHC | general purpose | Most commonly used among hot-rolled steel sheets, mainly used for flat plates and bent products. | SPCC | general purpose | This steel plate is suitable for punching, bending and shallow drawing, and is used for parts with simple shapes that require little processing. |
| SPHD | for diaphragm | Steel plate with excellent drawability next to SPHE. | SPCD | for diaphragm | Steel plate with excellent drawability next to SPCE. |
| SPHE | for deep drawing | Steel plate with uniform material and suitable for deep drawing. | SPCE | for deep drawing | It is a steel plate with excellent deep drawability, and because the crystal grains are adjusted metallurgically, it maintains a clean surface even after drawing. |
SPCC Steel Specifications
The common specification of SPCC cold rolled sheet is 0.5-3.0 mm*1,250 mm*2,440 mm; The max width and length can reach up to 2,000mm and 6,000 mm.
while the specification of SPCC cold-rolled strip and coil is 0.3-2.5 mm *355-1,500 mm.

Features of SPCC
SPCC is characterized by high workability and formability among carbon steels.
SPCC has high workability and formability
SPCC is known as a material with high workability and formability due to its low carbon content and softness. Especially suitable for bending and drawing. SPCC is also suitable for welding.
SPCC has a smooth surface
Due to its smooth surface, SPCC is highly decorative and can be painted or plated to achieve a more beautiful appearance.
SPCC is easily oxidized and easily rusts.
SPCC removes the surface oxide film. Therefore, it is easy to oxidize, and it is usually suppressed by applying oil at the time of shipment. In order to prevent oxidation, post-treatments such as painting, anti-corrosion treatment, and plating are indispensable after processing, such as Galvanized Steel, Galvalume Steel, Zin-alu-mg, Prepainted Steel stc.
Applications of SPCC Metal
SPCC steel is widely used in various applications due to its high strength, durability, and excellent surface finish. Here are some of its applications:
- Automotive industry: SPCC is used to manufacture automobile parts such as car bodies, engine components, and other structural components;
- Electrical appliances, such as refrigerators, air conditioners, and washing machines;
- Construction, such as roofing sheets, wall panels, and other structural components;
- Packaging materials, such as cans, drums, and containers.
- Furniture, such as cabinets, shelves, and tables.
- Industrial equipment: to manufacture various industrial equipment such as machinery parts, toolboxes, and storage racks.
Differences between SPCC and SPHC
The difference between SPCC and SPHC is the temperature range during manufacturing. SPHC is hot-rolled, and SPCC is cold-rolled SPHC, and their properties are very different.
“SPCC” is often selected when accuracy is prioritized, and “SPHC” is often selected when cost is prioritized.
Cost Comparison
| SPCC | SPCC is manufactured by further cold-rolling SPHC (at a temperature at which recrystallization does not occur), so work hardening occurs. Compared to SPHC, a greater force is required for processing, and the number of manufacturing processes increases, resulting in higher costs. |
| SPHC | SPHC is produced by hot rolling (higher than the recrystallization temperature), so there is no work hardening. The manufacturing cost is also low, and it is possible to obtain it cheaply unless it has a special thickness. |
Accuracy comparison
| SPCC | SPCC is characterized by small temperature changes in the material and high dimensional accuracy. It is possible to manufacture thinner sheets than SPHC. |
| SPHC | SPHC does not have high dimensional accuracy due to material temperature changes. |
Conclusion
SPCC stands for “Steel Plate Cold Rolled Commercial,” and it refers to a grade of cold-rolled steel. Its excellent formability, strength, and resistance to rust and corrosion make it a popular choice for a variety of applications. If you have any questions, please feel free to contact us!
