prepainted steel production line

Technical Data of production line

1.Outer diameter of the steel coil:800-2000mm

2.Inner diameter of the coil:508/610mm

3.Roller coating process:coating: continuous twice coating and drying on top side or both sides (laminated film system can be chosen: dry film laminating)

4.Thickness of color coating: Thickness of dry film on base coating can be 5~10μm (wet film is about 15~20μm). Thickness of dry film on top coating can be 5~15μm (wet film is 20~40μm).

5.Production capacity:100,000 ton one year

6.Energy: Natural gas, electric, diesel oil, liquefied gas, coal,propane and so on.(pressure force:50-100Mbar) (choose energy type according to the local energy requirement of customers')

7.Degrease form:Polar chemical degreasing+three - level water rinsing+Water spray.

8.Energy saving:exhaust gas and heat recycling.

9.Extremely-high economic benefits:

Pre-painted steel sheet,featured by durability and applicability,costs less in mounting and maintaining and has longer service life.Compared with the traditional coating method,the adoption of color-coated products can reduce the expenditures in human power,engineering,equipment and environmental protection.
