Lightweight and high strength: the specific gravity of steel is lighter than that of concrete, and the strength and toughness of steel are also very high, which can reduce the self-weight of buildings and improve the seismic capacity.
Convenient construction: the steel is produced in factory, and the site installation is simple, saving time, labor cost and resources. However, concrete buildings need on-site pouring and maintenance, and the construction cost is relatively high.
Corrosion resistance: After anticorrosion treatment, the service life of steel can be prolonged and the later maintenance cost can be reduced, especially in the coastline, industrial areas and other environments, steel structures are more advantageous.
Variety: steel can be processed into different shapes to create a variety of structural systems to meet different design needs and building types.
Recycling: Steel can be recycled, which is more environmentally friendly and conforms to the concept of sustainable development.
