China manufacture/Sell Prepainted Steel Production Line

Pre-painted steel coil production line for construction

For General building material,it use Polyester Coating as top painting,it is made through the process of chemical 

pretreatment,preliminary coating and fine coating on the continuous units.and it has good anticorrosion,forming,

decoration.and can make all kinds of new type material,such as corrugated roofing sheet,sanwich panels,

and be used for a variety of emerging industrial building.

Technical Data of production line

1>Ram material:

           Width:600-1500mm

           Thickness:0.15-1.5mm

           Material quality:

           Hot-dipped galvanizedsteel coil/Electro-galvanized steel coil

           /Cold rolled steel coil

2>Outer diameter of the steel coil:800-2000mm

     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>Productive power:100,000 ton one year

6>Energy: 

  Natural gas, electric, diesel oil, liquefied gas, coal,propane and so on.(pressure force:50100Mbar) (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:

  Prepainted 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.

10>Scope of product application:

Indoor decorating plate, furniture, ceiling of factory, external wall, external wall of decorating plate of modern 

building, chemical container, all transportation tools, such as boats, automobile etc..
