Color-coated steel roof panels should be color-coated steel sheets. Color-coated steel sheets belong to a category of profiled steel sheets. Color-coated sheets offer profiled steel sheet roof panels, color steel sheets, galvanized sheets, and aluminum-magnesium-manganese sheets. The color steel plate is formed after the surface of the cold-rolled, (aluminum) zinc-plated steel plate is painted and baked, and can be pressed again.
Galvanized iron is a layer of zinc plated on the surface of the steel plate, and the surface is bright gray. Or dark grey.
In foreign countries, there are many kinds of color-coated steel plates, and different industries use different color-coated steel plates as panels. For example, the side panels of refrigerators in Japan and South Korea usually use high-gloss single-color panels, and the refrigerator panels use high-gloss color panels or film-coated panels; in North America, most of the low-gloss panels, namely embossed panels, are used, which can be used during the embossing process. To enhance the strength of the steel plate, it can also cover the surface defects of the steel plate. The refrigerator panels with fried leather patterns on the surface are widely used in the United States; while the European home appliance industry generally uses low-gloss panels.
There are also many types of color-coated steel sheets in demand in the construction field. There are five or six types of substrates, such as hot-dip galvanized steel sheets, hot-dip galvanized steel sheets, hot-dip galvanized aluminum alloy steel sheets, zinc alloyed steel sheets, and aluminum-plated steel sheets. Alloy steel sheet, electro-galvanized steel sheet, etc. Therefore, for domestic color-coated steel plates, developing varieties and new products of color-coated steel plates and improving the technical content and added value of products is an urgent topic to be researched and tackled.
