Color-coated grades, consisting of pre-painted symbols and code base characteristics of the substrate type code in three parts, the third part is a two-digit number, namely 52, 53 and 54; the fourth part is the letter "D", on behalf of Redu. b) structural steel consists of four parts, of which the first part of the letter "S", on behalf of structural steel; the second part is the three figures, representatives of the specified minimum yield strength (in MPa), ie 250,280,300, 320,350,550; The third part is the letter "G", on behalf of the heat treatment; fourth part is the letter "D", on behalf of Redu. Substrate type code "Z" on behalf of galvanized substrate, "ZF" on behalf of galvanized iron alloy substrate, "AZ" on behalf of hot galvanized alloy substrate, "ZA" on behalf of galvanized aluminum alloy substrate, "ZE" on behalf of galvanized substrates. Engaged in construction or manufacturing people, certainly no stranger to Buy painted for color-coated coil, and are aware of color-coated applications. In fact widely caitu depends primarily on its excellent performance, for example, efficient construction, energy conservation, pollution prevention, etc. Of course, not just construction and manufacturing, but also the furniture industry, electronics industry, and so plays an important role. Then, in the development of our country caitu how what? First, the demand is still in a growth period. This year China's economy remains stable and rapid growth, the domestic market is still in steel demand growth, the Olympic project color coated paper plant in Shandong, northeast color coated coil Which is good, and the rest of the western development of urban infrastructure, industrial key projects demand will continue to grow for the second resource caitu adequate supply. By substrate shortage, domestic real output growth is not color-coated, currently abundant substrate, and color-coated market price has not yet stabilized, and therefore have the potential capacity of some domestic manufacturers are still waiting to see among the whole, even if does not consider the import of factors, domestic resources are more adequate color coated.
