Color-coated sheet is a product made of cold-rolled steel sheet and galvanized steel sheet as the base material, after surface pretreatment (degreasing, cleaning and chemical conversion treatment), continuous method (roller coating method) coating, baking and cooling. The main production processes of ordinary two-coating and two-baking continuous color coating units are as follows: uncoiling pretreatment, coating, drying, post-treatment, coiling.

The color-coated board is also very environmentally friendly, not easy to deform, fireproof and moisture-proof, and is very suitable for hotels as an isolation material for room layout. Retrofit can ensure the simplicity and refinement of the hotel and create different styles for the hotel. Therefore, from the perspective of its application range, it is not difficult to see the reason why the price of color-coated boards continues to rise.

I hope you can choose a regular large manufacturer and buy regular products. There are many reasons for the price increase of color-coated board, such as its wider application, more and more demand, or the growth of raw materials. Now I will take you to analyze the specific reasons. The reason why the price of color-coated steel plate continues to rise: The construction industry is an industry where color-coated steel plate is widely used. Now every city is developing rapidly, high-rise buildings are rising, and most of the color-coated steel houses of workers are in use. In addition, color-coated board is a plate product made of rock wool after machining and high temperature curing with a specific thermal insulation effect.

The basic concept of color-coated sheet: using cold-rolled strip and galvanized strip (electro-galvanized and hot-dip galvanized) as the base material, on a continuous unit, after surface pretreatment (degreasing and chemical treatment), one or more layers of liquid paint are applied by roll coating, and the plate obtained after baking and cooling is coated steel plate. There are back (bottom) paint and surface (front) paint in China, generally one layer of back paint and two layers of top paint in China, and two layers of top paint in foreign business.
