Construction hardware starts with hand-made workshops such as Tiepu, coppersmiths and tinsmith shops. China had a nail-making workshop in the Tang Dynasty. It used hand-made nails, latches, locks, and knockers. However, due to the use of wood and stone structures in ancient buildings, construction hardware has developed slowly in 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.
The building materials industry is an important material industry in China. Building materials products include construction materials and products, non-metallic minerals and products, and inorganic non-metallic new materials. They are widely used in fields such as construction, military industry, environmental protection, high-tech industries, and people's lives. At present, China is already the world’s largest producer and consumer of building materials. The main building materials such as cement, flat glass, building sanitary ceramics, stone and wall materials have been ranked first in the world for many years. At the same time, the quality of building materials continues to increase, energy and raw material consumption decline year by year, new types of building materials continue to emerge, and building materials products continue to upgrade.
In 2007, the output and benefits of the building materials industry increased substantially. From January to November, the building materials industry realized a profit of 79.6 billion yuan, a year-on-year increase of 56.6%. The increase in the level of equipment has led to a significant reduction in energy consumption in China's cement industry. In 2007, the comprehensive energy consumption per ton of cement was 138 kg of standard coal, which was a reduction of 4 kg of standard coal from the previous year. In the “Eleventh Five-Year Plan†period, investment in infrastructure construction has reached the middle plate, and the outbreak of investment in infrastructure construction such as roads and railways and the steady increase in ordinary civil construction investment have caused the construction industry to be on the upswing stage. At the same time, under the background of building an energy-saving society and the country’s ability to strengthen independent innovation, the theme of energy conservation and technological innovation will be a hot spot for the development of the industry.
