What is a steel structure?

Release:     Release date:2019-05-18

Steel structure is a structure composed of steel materials, is one of the main types of building structures.


The structure is mainly composed of beam steel, steel column, steel truss and other components made of section steel and steel plate, etc., and adopts silanization, pure manganese phosphating, washing drying, galvanizing and other rust removal and rust prevention processes. Welds, bolts or rivets are usually used to connect the members or components.


In the global scope, especially in developed countries and regions, steel structure has been reasonably and widely used in the field of construction engineering. Steel structure industry is usually divided into light steel structure, high-rise steel structure, residential steel structure, space steel structure and bridge steel structure five subcategories.

Extended information:

The characteristics of


1. High material strength and light weight


Steel strength is higher, the elastic modulus is also high. Compared with concrete and wood, the ratio of its density and yield strength is relatively low, so under the same stress condition of steel structure components section small, light weight, easy to transport and installation, suitable for large span, high height, heavy bearing structure.


2, steel toughness, good plasticity, material uniformity, high structural reliability


Suitable for bearing impact and dynamic load, with good seismic performance. The internal structure of steel is homogeneous, close to isotropic homogenizer. The actual working performance of steel structure accords with the calculation theory. Therefore, the steel structure has high reliability.


3. High mechanization degree of steel structure manufacturing and installation


The steel structural members are easy to assemble in the factory and the construction site. Factory mechanized manufacturing steel structure components finished products of high precision, high production efficiency, site assembly speed, short construction period. Steel structure is the most industrialized structure.
