Surface Treatment Of Cold Rolled Coil
- - - -
Surface Treatment | Feature |
Chemical Treatment | minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface |
retain the bright metallic luster for a long period |
Oil | minimize the tendency for humid-storage stain |
Chemical Treatment and Oil | The chemical treatment provides very good protection against humid-storage staining, while the oil provides lubricity for operations. |
Dry | must be transported and stored with special precautions to preserve low-humidity conditions. |
Anti-finger print | minimize the chance of humid-storage staining forms a dark gray surface discoloration on the surface |

Application Of Cold Rolled Coil
- - - -
Application | Features | Steel grades for example |
Commercial purposes | With some ductibility, they are suitable to simple forming, bending or welding | DC01, SPCC, St12 |
Drawing | With more ductibility than the common ones, they are suitable to manufacturing parts through drawing and relatively complicated deforming | DC03, SPCD, St13 |
Deep drawing | With more ductibility and homogeneity than the drawing ones, they are suitable to manufacturing parts through deep drawing and complicated deforming. | DC04,SPCE,St14 |
Extra-deep drawing | With more ductibility and homogeneity than the deep drawing ones, they are suitable to manufacturing parts through extra-deep drawing and more complicated deforming. | DC05, SPCF, St 15 |
Supreme extra-deep drawing | With more excellent drawing capability than the extra-deep drawing ones, they are suitable to manufacturing parts through supreme extra-deep drawing and extremely complicated deforming. | DC06, SPCG,? St16 |

Features Of Cold Rolled Coil
1. Resistance to Corrosion Has better performance in corrosion resistance than hot dip galvanized coil/sheet of the same thickness and its service life is 1-5 times longer than general hot dip galvanized coil/sheet.
2. Machinability Can satisfy the processing requirements of rolling, coiling and others processes alike.
3. Thermal Resistance Can sustain the environment at 315°C for long time.
4. High Reflectivity Reflection ability of heat and light is twice as much as those of hot dip galvanized steel coil/sheet, and its reflectivity is more than 0.75, exceeding 0.65 (required by the EPA Energy Star Standard), which is an ideal construction material of saving energy.
