Prepainted Sheet is produced by direct application of a paint (after applying a treatment and, in most instances, a primer) onto steel sheet in a coil-coating line. Coil-line painting can be used to apply a paint coating directly on uncoated steel sheet or on metallic-coated steel sheet. For maximum corrosion resistance, coil-line painting is often done on metallic-coated steels including galvanized, GALVALUME®, and terne coated sheet.

  Prepainted, coated steel sheet offers users a unique combination of advantages: the strength of steel, the corrosion resistance of a metallic coating and the beauty and additional corrosion protection of paint.

  Prepainted Coated Sheet offers users a custom prepainted, coated steel sheet ready for fabrication. Produced on high technology coil coating lines under rigid quality controls, this product has a painted finish that is uniform in color, gloss, texture and thickness, with excellent paint adhesion and durability. Today's combinations of metallic coatings and paint systems provide corrosion resistance and formability at levels considered impossible only a few years ago. Steel sheet can be readily rollformed, bent, and stamped without degradation in the quality of the paint.

  Prepainted steel sheet can be very cost-effective for fabricators of painted steel sheet products. Because it requires no in-plant painting either before or after fabrication, prepainted steel sheet eliminates the user's capital burden of paint facilities as well as painting costs associated with the preparation, handling, spraying and baking or drying operations. Also, the costs of meeting stringent disposal requirements for paint chemicals are eliminated. Users of prepainted sheet can realize significant savings in payroll, equipment maintenance, inventory, yield loss and other costs associated with operating in-plant painting lines. Prepainted sheet also offers the benefits of a faster and simpler operation without the worker-protection and environmental/pollution problems that accompany painting operations.

  By working closely with the paint suppliers and the coil coating industry, We has assisted in the development of primers and paints that offer very excellent qualities for the user. Paint hardness, paint gloss, resistance to chalk, fade, and peel, paint flexibility, and other attributes of prepainted steel sheet have been advanced to a high level of quality to enable its use for many industries including the automotive, appliance, furniture, and construction industries.

  During the past 10 to 20 years, there have been many advances in the development of prepainted steel sheet. In order to take advantage of these technological advancements, the user needs to take many issues into consideration. Today, these issues can be addressed very quickly because of the long list of successful applications that have been implemented. Questions that need to be answered include: the properties of the steel, the type of metallic coating if any, the metallic coating thickness, the paint attributes with respect to flexibility, hardness, chalk and fade resistance, etc. Obviously, these decisions depend on the application and the performance desired by the manufacturer.

Roll application of paint to steel sheet in a continuous coil-coating paint line. In this modern process, computer control ensures paint films of uniform high quality -- corrosion resistant and so tough, flexible, and adherent that they withstand forming of the sheet into many shapes.
