Coil Coating


Coil Coating describes the application of a decorative and/or protective organic coating to metal supplied in coil form. The finished product is known as ‘prepainted' steel or aluminium and is recoiled at the exit end of the coating line.

 

    TYPES OF METALS COATED:

  • Steel
  • Galvanised steel
  • Aluminium
  • Steel / Aluminium composites

 


Arcon supplies a range of Coil Coating Lines for ferrous and non ferrous materials from entry level stop/start lines through to fully continuous high speed lines. The lines include a wide variety of design features that produce a high quality product suitable for various markets.

 

CAPACITY


Arcon offers Coil Coating Lines with outputs from 10,000 - 150,000 tonnes per annum. The lines are designed to apply either a superior quality three coat system or an economical two coat system.

DESIGN PARAMETERS


Innovative designs make it possible to install a low capacity line, requiring a corresponding low capital investment, and then upgrade the line to output higher volumes as market demand increases. By designing a new line to easily accept later retrofitted equipment, future modifications can be made with minimal downtime to the existing line.

 

OVENS


Arcon offers a choice of Gas or Infrared curing ovens on colour coating lines. Gas ovens are proven technology and operate in many lines worldwide. Infrared ovens provide many cost and production benefits to coating lines, as the table below shows:

 

    ADVANTAGES OF INFRARED OVENS

  • Virtually no heat up or cool down time
  • Short length
  • The ability to vary line speed and follow variations with altered oven power, thus
        enabling proper paint curing under altered conditions
  • The ability to stop and start the line producing only small amounts of scrap
  • A heavy gauge coil can immediately follow a light gauge coil and the oven will
        immediately adjust thermal output to suit
