Five is a cover to build a comprehensive industry wide, multi-category, hybrid varieties, including six major categories, thousands of varieties: 1, doors and window hardware accessories, such as metal doors and windows, all kinds of hinges, door closers, floor springs etc.; 2, light steel keel, metal ceilings; 3, decorative hardware accessories, such as a variety of handles, door stays, door stop, door holder, door knockers, metal decorative pieces; 4, nails, wire, such as various types of steel 6, various casters; nails, screws, rivets and various special-shaped wire mesh, etc.; 5, plumbing fittings, such as faucets, civil valves, malleable iron pipe fittings and other pipe fittings and so on. As can be seen from the above products, building products based on traditional five new development yet, and with people's lives, a sunset industry. 2010 year, with hardware built five other industries showed a recovery of growth reached 27%, ranked third in the hardware industry. According to incomplete statistics, the domestic architectural hardware manufacturer over 10,000, accounting for 25% of the number of enterprises in the metal industry, according to customs statistics data, in 2010 architectural hardware exports 22.841 billion U.S. dollars, accounting for 39.7% of the hardware industry ( Hardware industry exports amounted to 57.511 billion U.S. dollars) in 2009, an increase of 32.2% over where nails, wire, mesh was $ 6.412 billion, an increase of 36.3%;. valves exports 5.806 billion U.S. dollars, an increase of 28.6%; faucet was $ 4.017 billion, an increase of 32.2%; pipe fittings to $ 3.514 billion, an increase of 35%; door and window hardware accessories exports of $ 1.745 billion, an increase of 20.8%; hinge products exports $ 761 million, an increase of 38.9%. Architectural hardware products in the exports of metal products ranked first, exporting large hardware industry has a pivotal position in the hardware industry. But there are still many hardship to build five, from 2010 customs statistics architectural hardware products imports can be seen, in 2010 imports amounted to 10.684 billion U.S. dollars, an increase of 22.6%, which is the major parts of the doors and windows hinge 2010 than the 2009 growth rate of 47.3% in the amount of imports, which shows in our high-end market is still dominated by foreign brands. Currently our extensive mode of development behind serious excess capacity, low-end products, less high-end products, but there are still some products like God does not like the situation, the lack of core technology, the lack of independent intellectual property rights, lack of world-famous brand, the lack of core competitiveness . Unfortunately, we are now building hardware industry is not a state-level enterprise technical centers.
