The reasons for chosing DG steel structure building:
1. High strength: Under the same load, steel structure bear the smallest section; On the same section, steel structure have the ultimate bearing capacity

2. Light weight: Generally speaking, the ratio of the dead weight of steel structure against reinforced concrete is 1: 6. The weight of a six-story light steel resident equals to a four-story brick concrete steel tructure

3. Low cost: Effectively improving the indoor space by applying steel structures, and can significantly reduce the load-bearings. While the cost is only 2/3 as the equivalent of civil engineerings;

4. Application scope: Industry, workshop, warehouse, and other industrial facilities. Commerce: Mall, hotel,
Exhibition hall, hospital, office building. Public: The social activity center, school, library, sports stadium, church etc.

5. Perfect design: The biggest single span can reach up to 70 m; Our design is based on the customers' local weather conditions, using the right materilas, which is in line with the local enviroments. Meanwhile, the whole steel frame system is strong and stable enough by the bonding of steel members;

6. Environment-friendly: Nicknamed green building, steel structure building costs less energy when under construction and it can also be recycled, which has more advantage than civil engineering.
