In this article, let Baowu take you to understand the reasons for the color coating of steel.

Color-coated steel sheets are made of cold-rolled steel strips and galvanized steel strips as substrates on a continuous unit. After surface pretreatment, they are coated with one or more layers of liquid paint by roller coating, and then baked and cooled. plate.

Since the coating can have various colors, it is customary to call the coated steel sheet color coated steel sheet. Color-coated steel plate is an organic coating applied to the surface of the steel. It has the advantages of beautiful appearance, bright color, high strength, good corrosion resistance, convenient processing and forming, and can also reduce costs and pollution for users.

The reason why the steel plate is color-coated is that the steel plate after color-coated will have more characteristics:

Pollution resistance. The color-coated steel plate has strong anti-pollution performance. Apply ketchup, lipstick, coffee drinks, edible oil, etc. on the polyester coating surface, and after 24 hours, wash and dry with washing liquid, the surface gloss, color No change.

High temperature performance. The color-coated steel sheet was continuously heated in an oven at 120 °C for 90 h, and the gloss and color of the coating did not change significantly.

Low temperature resistance. The color-coated steel plate was placed at a low temperature of -54 °C for 24 h, and the bending and impact resistance of the coating did not change significantly.

Boiling water resistance. After the samples of various coating products were immersed in boiling water for 60 minutes, the gloss and color of the surface did not change, and there were no phenomena such as blistering, softening, and swelling.

Color-coated steel plates can be used as building interior and exterior wall panels, suspended ceilings, roof panels, tile panels, corrosion-resistant equipment, components, baseboards, floor panels for facade signs, etc., and can also be used as waterproof penetration panels, exhaust pipes, ventilation Pipes, corrosion-resistant pipes, furniture, water baffles, electrical equipment covers, car shells, etc. The color-coated steel plate can also be made into a profiled plate, and its section shape and size are basically similar to the aluminum alloy profiled plate. Because it has the advantages of good durability, beautiful appearance and convenient construction, it can be used for the walls and roofs of industrial plants and public buildings.

The above is the relevant content of color-coated steel plates and the reasons why the steel plates should be color-coated. If you want to know more, please feel free to pay attention to Baowu.
