Color Coated Steel

International Steels “ISL” Continuous Color Coil Coating facility was developed using wet paint coating technology.

The 84,000MT facility allows us to produces high quality color coated sheets on various substrates like Cold Rolled, Galvanized, Galvalume, Aluminum and Stainless steel sheets. The high quality color coating enhances the corrosion resistance substrate and adds to the aesthetic appeal.

Production Facility

ISL's manufacturing facility is strategically located in the port city of Karachi, the state-of-the-art facility comprises of machinery supplied by some of the most renowned steel processing equipment suppliers in the world.

Our color coating complex comprises of a state of the art continuous high-speed two coat-two bake system line enabling application of primer and topcoat in the same run, this allows for a superior uniformed color thickness with highly reproducible colors and gloss levels. The line is also capable of coating the front and back in two colors in a single run and can therefore provide different coating on both sides. The plant meets environment protection standard as rollers apply paint and the drying treatment is free of chemicals.

Paint Systems

ISL uses Polyester (PE), PVDF and Polyamide paint systems.

  • PE paint system is economical and is recommended for materials exposed to normal atmospheric conditions.
  • PVDF paint is used on materials exposed to severe atmospheric conditions due to its and stable corrosion and UV resistance.
  • Polyamide paint system in combination with high build primers used on materials exposed to a corrosive environment as it is oxidation resistant, UV durable and has improved scratch resistance.
