structural steelwork is mainly made of steel,mainly composed of steel and steel plate, steel structure building , steel truss and other components, the components are usually connectioned by welding, bolt or rivet, is one of the main types of building structures. Because of its light weight and simple construction, it is widely used in large factories, bridges, venue, super high-rise and other fields.
Although China has made remarkable achievements in iron structure in the early stage, due to the shackles of the feudal system for more than 2000 years, the science is underdeveloped, so it has long stayed at the level of iron buildings. Until the end of nineteenth Century, China began to adopt modern steel structure. After the founding of new China, the application of steel structure has made great progress, both in quantity and quality is far more than the past. China have reached a higher levelIn the design, manufacture and installation technology. And know well various design and construction technology of complex buildings, and have built many large scale and complicated structure of the steel structure workshop,steel structure warehouse, civil construction and railway steel structure of large span bridge, the Great Hall of the people in our country steel truss, steel the grid of Beijing and Shanghai and other places of the stadium, the three hinged steel arch of Shaanxi Qin Shihuang Museum of terracotta warriors and Beijing's bird's nest etc.. all over the country.
