Upstream and downstream impact of the steel industry, the steel industry in Dongguan mainly steel design, steel product price fluctuations directly affect the procurement costs of the industry. Overall, the upstream industry basically competitive steel industry, the production of various types of steel used in steel structures, steel, steel and other steel products, including H-beam and plate steel building is the most commonly used products. Industry Insights research data in 2011 amounted to 696 million tons of crude steel production, steel production is relatively saturated Dongguan materials needed for the production of steel to get a steady supply of raw materials. The development of downstream industries of steel industry has greater traction and driving action, changes in demand that they directly determine the future development of the industry. Steel for its high strength, light weight, good seismic performance, high degree of industrialization, short construction period, plasticity, energy saving and other comprehensive advantages in industrial plants, municipal infrastructure, Sporting construction, electricity, bridges, offshore oil engineering, aerospace and other industries has been widely used, and gradually expand the market space. In addition, once the housing market breakthrough steel steel metal housing, gradually replacing the traditional architectural forms to enter the residential construction industry, steel industry will lead to explosive growth. Construction quality steel works may variability problem with the extension of the outside world will change and the time and constantly evolving, quality defects gradually reflected. For example, the weld steel member changes due to stress, so they had no weld cracks cracks: As the role of hydrogen after welding activities can be delayed in the weld cracks. Another example is the component of long-term bear overload, the steel components to be produced under the arch bending deformation, resulting in problems. Frequent sex is due to our modern building with concrete structures mainly engaged in construction management and technical staff of the steel fabrication and construction technology is relatively unfamiliar to migrant workers mainly construction workers but do not know the specific steel works The scientific construction methods, resulting in the construction process of frequent accidents.
