China One of Hottest for Cold Rolled Steel Surface Finish - Skin passed EN10130 Grade DC01 SPCC cold rolled steel coils - Ruiyi Manufacturer and Supplier | Ruiyi

SPCC cold rolled coil is commonly known as cold plate. It is made of ordinary carbon hot-rolled steel strip, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Among them, the delivered sheet is called SPCC cold-rolled coil, also called box plate or flat plate; the length is very long, and the coil is delivered. The goods are called steel strips, also called coils. Because rolling at room temperature does not produce iron oxide, compared with hot-rolled coils, the surface quality, appearance, and dimensional accuracy of SPCC cold-rolled coils are significantly better than that of hot-rolled coils, and the thickness of their products is as thin as About 0.18mm, so it is favored by the majority of users and is widely used in industries such as automobiles, home appliances, hardware, aviation, industrial equipment, and construction. In addition, SPCC cold-rolled coils are also used as substrates for deep processing and become high value-added products. Such as electro-galvanized, hot-dip galvanized, fingerprint-resistant electro-galvanized, color-coated coil and vibration-damping composite steel, PVC composite steel and so on.

SPCC/SPCCT: Common & General Use; Characteristics: Suitable for bending processing and simple deep drawing processing, is the most demand varieties; Applications: Refrigerators, rails, switchboards, iron baskets and so on.

SPCD: Drawing & Stamping Use; Characteristics: Second only to SPCE, is the quality of the smaller deviation of the drawing steel plate; Applications: Automobile chassis, roof and so on.

SPCE/SPCF: Deep Drawing & Stamping Use; Characteristics: Grain is adjusted, deep drawing performance is excellent, after the stamping can get a beautiful surface. Applications: Car fender, rear side panels and so on.

SPCG: Extra-Deep Drawing & Stamping & Punching Use; Characteristics: Very low carbon cold rolled steel, excellent deep drawing processability. Applications: Car interior board, surface and so on.

Remarks: SPCCT is users specified the grade of SPCC which need to ensure that the tensile strength and extensibility of the species. SPCF, SPCG will need to ensure that there have non-aging (not due to the occurrence of tensile deformation of the property), after outside factory for 6 months – that is, SPCC, SPCD, SPCE if stored for a long time, will produce mechanical performance changes, especially to reduce the cold stamping performance, it should be used as soon as possible.

Surface:
FB: higher finishing surface: Does not affect the formability and coating, plating adhesion defects, such as small bubbles, small scratches, small roll, slightly scratched and oxidized color allowed to exist.

FC: advanced surface finishing: The better side of the steel plate must be further limited to the defect, no obvious visible defects, the other side should meet the FB surface requirements.

FD: extra-advanced surface finishing: The better side of the steel plate must be further limited to the defects, that is, does not affect the appearance of paint or after plating quality, the other side should meet the FB surface requirements.

Surface structure:
Surface Structure Code Average roughness Ra / μm
Pitting surface D 0.6~1.9
Bright surface B ≤0.9

Cold-rolled coils are widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans, printed iron drums, construction, building materials, bicycles and other industries. At the same time, it is also the best choice for the production of organic coated steel plates.
