The color coated steel roof panel should be color steel plate. The color coated steel plate of the company belongs to the type of profiled steel plate. The color coated steel plate quoted price is divided under the profiled steel roof panel, color steel plate, aluminium-galvanized plate, aluminium-magnesium-manganese plate. Coloured steel sheet is formed on the surface of cold-rolled (aluminized) zinc-plated steel sheet after painting and baking, and can be re-pressed.
Galvanized iron sheet is coated with zinc on the surface of steel sheet, and the surface is bright gray. Or dark grey.
In foreign countries, there are many kinds of color-coated steel plates, and different industries adopt different color-coated steel plates as panels. For example, the side panels of refrigerators in Japan and Korea are usually made of high gloss single color panels, while the front panels of refrigerators are made of high gloss single color panels or cladding panels; in North America, low gloss panels are mostly made of embossing panels, which can not only enhance the strength of steel plates in embossing process, but also cover the surface defects of steel plates. The fridge panels with fried leather pattern on the surface are widely used in the United States, while in European household appliances industry. Low light plate is generally used.
There are many kinds of color-coated steel sheets needed in the construction field. There are five or six kinds of base plate, such as hot-dip galvanized steel sheet, hot-dip aluminium-zinc alloy steel sheet, hot-dip galvanized aluminium alloy steel sheet, galvanized alloy steel sheet, aluminium-plated steel sheet, galvanized steel sheet, and so on. Therefore, for domestic color-coated steel plate, it is an urgent task to develop varieties and new products of color-coated steel plate and improve the technical content and added value of products.
In the next 10 years, China's color coated steel plate market will be more and more promising, and there is a great space for development. However, facing the increasing integration of the international market, foreign products will enter the Chinese market in large quantities, and the competition will become more and more fierce. For example, Australian BHP Group has extended color coated steel plate to Yunnan, Chengdu, Xi'an and other places in China. At present, BHP has established subsidiaries in Tianjin, Shanghai, Guangzhou and other cities in China. The annual sales volume of color coated steel plate has risen from 20,000 tons to 50,000 tons, and the market sales price has risen by about 5% this year. It is reported that BHP Group will also set up a number of subsidiaries in the western region, such as Xi'an, Yunnan and Chengdu. In 2003, the sales volume of color aluminized and galvanized steel coils in the Chinese market will strive to increase by 20% to 30% on the basis of 2002.
The potential huge market of color coated steel sheet, how to expand the market share of domestic products, still need to be further explored and studied by iron and steel enterprises and steel traders.
