Colour coating Line

Colour coating usually refers to the application of liquid paint coat over the substrate in an automatic, continuous process after pre-treatment. The pre-painted colour coated steel is a very high value-added product that combines the best properties of both substrate and organic coating, additionally imparting it an aesthetic finish, high degree of durability and high corrosion resistance. The thickness of colour coating is usually in the range of 15 microns to 40 microns and the finishes are smooth, matt, high gloss, textures and printed. For standard colour coated sheet, the thickness of substrate steel usually varies from 0.2 mm to 1.6 mm and width varies from 600 mm to 1600 mm.

Colour coating is done on various substrates of steels to produce most cost effective, quality assured products with the top coat compatible with environment. The substrate steels normally used are given below.
