Construction hardware starts with hand-made workshops such as Tiepu, coppersmiths and tinsmith shops. China had nail-making workshops in the Tang Dynasty. Hand-made nails, latches, locks, and knockers were used. However, due to the use of wood and stone structures in ancient buildings, construction hardware has developed slowly over the past few millennia. After the 19th century, with the widespread use of metal materials and the needs of social life, building hardware has been rapidly developed, and many small steel nails, hinges, latches, window hooks, tap fittings, wire braided screens, etc. have appeared. Factory or workshop. Later, it gradually adopted mechanical processing equipment instead of hand-made, forming a number of specialized companies. With the continuous improvement of various building facilities standards, modern architectural hardware products have evolved from a single species to serialization, and their aesthetic and decorative effects have become increasingly demanding. The production process of architectural hardware products has also made great progress. Most of the products have been developed from semi-manual and semi-mechanical operations into semi-automatic or fully automatic mechanical line production. Architectural hardware has been expanded from traditional copper alloys, low carbon steels, etc., to zinc alloys, aluminum alloys, stainless steels, plastics, fiberglass and various composite materials. However, the development of the construction hardware industry has also presented a series of problems.
According to statistics, in 2010, China's presidential hardware imports amounted to 10.684 billion U.S. dollars, an increase of 22.6% year-on-year, of which hinged products for the main components of Doors And Windows increased by 47.3% in 2010 compared to 2009, indicating that China's high-end market is still occupied by foreign brands. At present, our development methods are extensive, and there is a serious surplus of backward production capacity. There are many low-grade products, and there are few high-end and middle-grade products. Some of our products are still not similar in shape, lacking core technologies, lacking independent intellectual property rights, lacking world famous brands, and lacking core competitiveness. . Unfortunately, at present, we do not have a national-level enterprise technology center in the architectural hardware industry.
Locks are an important part of the construction hardware industry. Although there are a large number of enterprises in the lock industry in China, most of them are small-scale enterprises with backward technologies, low grades of products, and poor competitiveness. Enterprises that have independent research and development capabilities and directly participate in international competition Too little, revitalizing the Chinese lock industry has a long way to go.
