Update time:2020/08/07 18:04:08  Click:  
Analysis of the architectural characteristics of modern steel structures. The degree of pre engineering is high, the construction cost is reduced, and the construction period is shortened. The coordinated and unified standard of steel structure building modules has achieved large-scale industrial production of buildings, improved the pre engineering of buildings, and made building components with different materials, shapes, and manufacturing methods have a certain degree of universality and interchangeability. At the same time, the pre engineering of steel structure buildings integrates material processing and installation, greatly reducing construction costs; And it has accelerated the construction speed, shortening the construction period by more than 40%, thereby accelerating the capital turnover speed of real estate developers and enabling the buildings to be put into use earlier.
