Society is developing rapidly, steel structure is developing rapidly, and many construction projects are using steel structure. Why use steel structure and what are the advantages of using steel structure? 

First, because the steel structure engineering can better satisfy the requirements of sensitive separation of large bay than the traditional construction, and can improve the area utilization rate by reducing the cross-sectional area of columns and using light-weight wallboard, and the indoor useful use area can be improved by about 6%.

Second, due to the good energy-saving effect of steel structure engineering, light energy-saving standardized C-section steel, square steel and sandwich panel are selected for the wall, which has good thermal insulation performance and good seismic resistance.Energy saving 50%.

Thirdly, if the steel structure system is used in the residence construction, it can give full play to the steel structure with good ductility, strong plastic deformation ability, excellent seismic and wind resistance performance, and greatly improve the safety and reliability of the residence.Especially in the case of earthquake and hurricane disaster, steel structure can avoid the collapse of buildings.

Fourth, because the total weight of steel structure construction is light, the self weight of steel structure residence system is light, which is about half of that of concrete structure, which can greatly reduce the fundamental cost. 

Fifthly, the construction speed of steel structure engineering is fast, and the construction period is at least one third shorter than that of traditional residence, workshop, canopy and other systems. It only takes 20 days and five workers to complete a 1000 square meter building. 

Sixth, steel structure engineering has good environmental protection effect.For example, the amount of sand, stone and ash is greatly reduced during the construction of steel structure residence. The data used are mainly green, and 100% recycled or degraded data. When the buildings are removed, most of the data can be reused or degraded, and no waste will be formed. 

Seventh, the steel structure engineering is sensitive, rich and practical, can be large bay planning, indoor space can be cut in multiple schemes, can meet the different needs of users.
