Characteristics of steel

Steel of features is strength high, and weight light, and overall rigid good, and deformation capacity strong, so for built big span and super high, and super heavy of buildings special suitable; material uniform quality sex and isotropic good, is ideal elastic body, most meet general engineering mechanical of basic assumes that; material plastic, and toughness good, can has larger deformation, can is good to bear power load contains; building duration short; its industrialization degree high, can for mechanized degree high of professional production. Steel structure research of high strength steel, greatly improving their yield-point strength, in addition to new varieties of rolled steel, for example, h (also known as wide flange steel) and the t-shaped steel and steel plate to fit large-span structures and high-rise building needs.
