Caitu in use environment is not the same color coated paper manufacturer in use require a screw in a supporting role, can improve the life of color-coated, following the Xiaobian to introduce how to screw in color coated board applications play an important role because of its ocean-atmosphere contains salt, with strong corrosion. Steel from the coast nearer the more severe corrosion, the corrosion rate is many times higher than inland atmosphere. Steel contact with the timber, the timber due to moisture after the secretion of acid, causes severe corrosion of metal. Practice has proved that to reach more than 30 years of age, you must use AISI304 or 316 stainless steel screw, which is Europe's first choice for steel construction fasteners. Can prevent the occurrence of corrosion fundamentally. Watertight gasket and screws have a great relationship quality, the introduction of Switzerland SFS fastener system with a EPDM waterproof gasket, unique performance, temperature -50 ℃ ~ + 100 ℃, resistance to ozone and ultraviolet light, can effectively resist outdoor weathering, the volume of the gasket has a sufficient elasticity, can adapt to the displacement of the screw and the installation error. "EPDM" waterproof gasket optimized design, the screws are in place, the top of the screw can close the inner gasket to prevent moisture intrusion. SFS stainless steel screw fastening systems and supporting washer fully applicable to the open structure of the roof, the roof drilling and fastening on purlins. The use of hidden structure, although not exposed screws, in order to resist the water film and "acid rain" erosion of house member, must also be made of stainless steel screws. Therefore, we must not be careless in choosing color coated fine without error. Caitu in the country has a large market in Shandong Binzhou color coated paper, Boxing is color-coated, galvanized sheet distribution center, the following analytical about what color coating of color-coated market problems. Second, the lack of high-end products, the low-end products, excess capacity currently caitu grade domestic product is relatively low, high-quality, high-tech, high value-added products less, these products still can not meet the needs of the market, while the low-end general product capacity is large, there have been excesses. China's high-grade painted steel color coated paper market prospect is very broad picture, but China is capable of producing high-grade painted steel manufacturers small, limited production, some products along genus blank color coated paper, need to be developed. It should be said, the past few years, the domestic color coated steel plate has been greatly grow in capacity, variety, size and quality, particularly in the development of more rapid production of domestic low-level redundant construction and vicious competition in the market makes prepainted also makes a lot of investment of tens of millions of units put into discontinued. Caitu industry is a very promising industry. Color coated paper use, Gannan color coated paper, steel Jinhong Run by Boxing Xingfu Town 金宏润 Steel Industry and Trade Ministry.
