building hardware manufacturers have a long history. It can be said that architectural hardware started in hand workshops such as ironsmith shops, coppersmith shops and tinsmith shops. In the Tang Dynasty, China had a nail-making workshop, which made nails, door latches, locks, and door knockers by hand. However, due to the use of wood and stone structures in ancient buildings, the development of architectural hardware has been slow in the past few thousand years. After the 19th century, with the widespread use of metal materials and the needs of social life, construction hardware has developed rapidly. There have been many small manufacturers of steel nails, hinges, latches, window hooks, tap valves, and wire woven screens. Factory or workshop. Later, mechanical processing equipment was gradually used to replace manual production, forming many specialized enterprises. With the continuous improvement of the standards of various building facilities, modern building hardware products have developed from a single variety to a series, and the requirements for their beauty and decorative effects are getting higher and higher. The production technology of construction hardware products has also made great progress. Most products have been developed from semi-manual and semi-mechanical operations to semi-automatic or fully automatic mechanical assembly line production. Building hardware has expanded from traditional copper alloys and low-carbon steels to zinc alloys, aluminum alloys, stainless steel, plastics, glass steel and various composite materials.
