In modern construction projects, reinforced concrete structures have been widely used, and as a special building material, steel plays an extremely important role. In 2009, the total amount of steel used for construction in China exceeded 110 million tons, which is close to half of China's steel output. It is the largest user of metallurgical industry in China, and the consumption of threaded steel accounted for about 23% of the total amount of steel. However, the standard shape of rebar used for construction is messy, and the rebar material produced by rebar factories can not be directly used in engineering. Generally, it is required to pass the process according to the requirements of construction drawings.
现在大部分地区修建用钢筋长期以来依托人力来进行加工，随着一些钢筋加工设备的呈现，才使之变为半机械化加工方法，加工地址主要在钢筋销售点或施工工地现场 进行加工，由于所运用的钢筋加工机械技能功能、自动化程度和加工能力较低，严峻限制修建施工现代化的进步，给施工管理带来很大的麻烦，而且这种加工方法具 有劳动强度大，加工质量难以控制，加工功率底，材料和能源浪费高，加工本钱高，安全隐患多，占地大，噪音大等缺陷。
At present, most of the construction of steel bars have been processed by manpower for a long time. With the appearance of some steel bar processing equipment, it has become a semi-mechanized processing method. The processing address is mainly processed at the steel bar sales point or construction site. Due to the low function, automation and processing ability of the steel bar processing machinery, the construction is severely restricted. The progress of modernization has brought great trouble to construction management, and this processing method has such defects as high labor intensity, difficult to control the processing quality, low processing power, high waste of materials and energy, high processing cost, many hidden dangers of safety, large occupation of land and large noise.
The so-called commercial processing and distribution of construction reinforcement means that the various types of reinforcement required by the project are automatically controlled by mechanical processing according to the actual scale of the construction structure (straightening and shearing of wire bars, shearing of bar bars at fixed length, bending and bending of steel bars, forming of steel mesh, mechanical jointing of steel bars, forming of large prefabricated steel bars such as steel cages and columns, etc.). It is transported to the construction site for direct use at the actual construction time.
混凝土结构修建工程施工主要分为三个部分：混凝土、钢筋和模板。这三个方面的开展情况反映了修建工业化和施工技能的开展水平。开展钢筋商品化加工配送是为了 改变修建用钢筋加工分散落后面貌，以先进技能手段和方法实现化、规模化运营，进步钢筋加工质量，为施行先进的施工技能提供物质基础，必然会进步工程质 量、下降工程本钱、进步机械化施工水平，添加经济效益和社会效益，契合社会开展的需求。
The construction of concrete structure is mainly divided into three parts: concrete, steel bar and formwork. The development of these three aspects reflects the development level of construction industrialization and construction skills. The purpose of developing commercial processing and distribution of reinforcing bars is to change the backward situation of reinforcing bars in construction, to realize specialized and large-scale operation with advanced technical means and methods, to improve the quality of reinforcing bars processing and to provide material basis for implementing advanced construction skills, which will inevitably improve engineering quality, reduce engineering cost, improve the level of mechanized construction, and to add economic and social benefits. Benefits are in line with the needs of the society.
Steel bar processing and distribution is the demand of basic construction.
Construction industry has been listed as one of the four pillar industries of national economy. During the Tenth Five-Year Plan period, the focus of investment is still infrastructure construction and residential industry. The real estate industry will continue to grow rapidly before 2010: in 2008, the completed area of township houses reached 482,000 square meters, using 183,000 tons of steel; in 2009, the completed area of township houses reached 513,000 square meters, using 19,000 tons of steel; in 2010, the completed area of township houses in China is estimated to reach 600,000 square meters, using 22,800 tons of steel. Large-scale construction projects provide a broad market for steel bar processing products.
