In green environmental protection has become today's life theme today, stainless steel cistern is more and more valued. In some metropolises in China, water supply departments have made strict regulations on the selection of materials for roof water tanks of new residences. According to Shanghai tap water company about personnel introduction, in last few years, stainless steel cistern is used in Shanghai nearly 100 new residential area, the effect is good. It is expected that in the next few years, stainless steel water tank will become a new growth point of domestic stainless steel consumption.

Same, conduit of stainless steel also is "12th five years" a main field that is applied in construction industry during, because conduit of stainless steel has anticorrosive, sanitation, light weight, maintenance is little, the advantage such as long life. Stainless steel conduit is in developed country already popularize day by day, the conduit stainless steel of Tokyo area is changed already achieved 90% above, conduit leakage quantity drops by original tens of thousands of places 2 / year ~3 / year. According to the national standard ANSI/NSF61-1996a formulated by the U.S. government in 1996, only stainless steel and ductile iron pipes are allowed to enter the water supply pipes of high-rise buildings. Stainless steel pipes are selected.

In recent years, a few cities of our country also use stainless steel conduit. As early as 2003, China's ministry of Construction issued a new revision of the "building water supply and drainage code", "stainless steel clamping pipe", "building water supply thin-wall stainless steel pipe engineering technical specifications" and other national standards and specifications, marking the application of stainless steel thin-wall pipe time has been mature. Shanghai has piloted drinking water directly into the household, drinking water pipes choose stainless steel water pipes; The cold and hot water pipes and direct drinking pipes of Shanghai World Expo related projects are all made of stainless steel thin-walled pipes. Thin-walled stainless steel pipes and clamping fittings have been used in the water supply system of some high-grade commercial buildings. Pipeline direct drinking water in Beijing, Shenzhen, Shanghai, Chongqing and other cities are developing rapidly, the economic development of medium-sized cities are also actively planning to catch up. At present the guesthouse of domestic grade, public place already configured or pipeline of straight drinking water is in configuration, stainless steel conduit is in "12th five year plan" the amount that should consume in construction industry will increase obviously, potential market is very huge.

At the same time, the plan proposes that during the 12th Five-Year Plan period, the amount of steel bar above HRB400 in the construction industry will reach 45% of the total amount. Then, the future stainless steel reinforcement will be promoted and applied in the construction industry. In addition to corrosion resistance, stainless steel bar also has high yield strength, toughness and ductility and fatigue resistance. Stainless steel bar has been used in bridge construction. Some domestic steel mills have successfully trial-produced 316L, 2205, 2304 stainless steel thread rebar, and the Ministry of Transport highway research institute cooperation related application research, for stainless steel plate, stainless steel wire into the road, bridge and other industries laid a foundation.

Industry experts believe that the main characteristics of stainless steel reinforcement is that the surface of stainless steel has a self-healing layer of chrome-rich oxide film, its excellent corrosion resistance not only makes stainless steel a choice of building components, or reinforced concrete components in the carbon steel bar as an alternative material. The use of stainless steel steel bars in reinforced concrete structures enhances strength and resists corrosion of embedded steel bars by harsh Marine environments and chlorides formed in concrete. Corrosion resistant stainless steel concrete is used on the deck of many Marine buildings, pier, pier, pile foundation, slope embankment, anchorage system, mooring tools, gangway, balustrades, and in urban infrastructure, such as street overpass, stainless steel reinforced concrete structure is also used. Compared with ordinary carbon steel steel bar, the cost of stainless steel bar is higher, but from its good comprehensive performance and service life is cost-effective. With the continuous development of society, in the future construction industry, stainless steel bars will gradually be widely used, and slowly replace the status of ordinary carbon steel.

"Twelfth five-year" period, stainless steel in the construction industry will show their talents. People firmly believe that with the improvement of China's comprehensive national strength, as well as the expansion of stainless steel production scale, product types, quality improvement, the application of stainless steel in the construction industry will open a new situation.
