1.The structure of light weight. Compared with the concrete structure, the weight is lighter, and the reduction of the structural self-weight reduces the internal force of the structural planning. It can reduce the need for the construction of the foundation. The construction is simple and the construction cost is reduced. 2. C-shaped steel planning personality is sensitive and generous. In the same case of high beam height, the opening of the steel structure can be 50% larger than the opening of the concrete structure, and then make the construction and placement more sensitive.
3. The steel structure mainly made of hot-rolled C-shaped steel has scientific and reasonable structure, good plasticity and flexibility,high structural stability. It is suitable for structures that are subjected to large shock and vibration loads and has strong natural disaster resistance. It is particularly suitable for Construction of some seizure belts. 4.Add a useful structure to use the area. Compared with the concrete structure, the steel structural column has a small cross-sectional area, and then it can be added to construct a useful use area, and depending on the way of construction, a useful use area of 4-6% can be added. 5.Compared with welded c-shaped steel, can obviously save labor and materials, reduce raw materials, power and labor costs, low residual stress, good appearance and surface quality. 6. easy to mechanical processing, construction of convergence and devices, but also easy to remove and reuse.
