Color Coated Steel Coil Brings Better Protection and Usability

Color coating on the steel gives it a protective organic coating that gives the steel long-lasting protection even in corrosive conditions. This coating does not enhance the strength of the steel but gives it the required protection in order that its integrity and strength are maintained.

The procedure of creation of color coated steel coil is certainly one that is certainly highly automated. This coating is likewise referred to as a duplex coating. This organic coating is applied in the coil within a continuous method that includes its cleaning, chemical pre-treatment, and the effective use of primers and paints. The paints are then cured or could be laminated with permanent films of plastic.

Europe pioneered industrial coating lines within the 1940s and also the advantages it had made it increasingly popular, like higher productivity, economical, consistent properties from the sheets, and lesser wastage of the coating material. The pre-painting of sheets in controlled conditions gives these coatings a benefit across the same galvanized sheet being painted after it really is set up in any application. Finishes are smooth, can have high gloss, matt, or textured finishes. The thickness of coatings change from 15 to 40 microns. Standard galvanized colored sheets have thicknesses that vary from 0.12 mm to 1.6 mm and widths change from 600 mm to 1600 mm. Lengths can differ based on the customer requirements.

Color coating can be employed on any type of steel, whether it be cold-rolled or galvanized. Galvanizing the steel can be a separate process, where zinc or a mixture of zinc and aluminum is applied to the steel by hot dipping it in these metallic solutions. So a color-coated steel coil may have this coating of zinc on the base metal which is then further protected with the color coating. This coating can have a pre-treatment chromate coating, a primer coat, and therefore the topcoats of paint. It may also be given a guard film.

One coating line will coat both cold rolled steel and steel that has received some other metallic coating. In this particular process, the coil is uncoiled along with its head mechanically joined for the previous coil that has been coated. Before any paint or primmer is used to the steel coil, it needs to be pre-treated in order that there is certainly better adhesion of the paint. This is achieved by making use of a chemical treatment that helps the top of the steel to bind with any coating. The strip might need to be washed and dried before any chemical is used that can give the pre-treatment chromate coating.

Once the pre-therapy is completed the coil will likely then obtain a coat of your chosen primer. These primers also contain corrosion inhibitors and will be of several types depending on the paints that happen to be to create the hue coating.The color coating line is equipped to make use of the primer or paint on sides simultaneously, in the strip being coated. In the end the coats are applied, the strip then passes in a convection oven, in which the coatings are cured by heat.

This completes the procedure of color coating of the galvanized steel coil.
