Some problems existing in the development of steel structure processing

        As we all know, the steel structure grid plays an important role in the construction and other aspects, but there are two sides to everything.

   1. Due to the characteristics of steel itself, the fire resistance of steel structure itself is not very good, and the fire resistance is relatively poor. In case of fire, although the steel itself will not burn, with the increase of temperature, all aspects of the performance of the steel structure grid will change, including its bearing capacity and balance stability will also be affected.

       2. For long-term exposed steel structure grid, a layer of coating must be used outside to prevent steel corrosion. However, due to the limitation of the service life of the coating itself, many problems will be caused to the steel structure in the later stage. Therefore, when choosing the coating, we must pay attention to the appropriate selection to avoid the waste of resources caused by this harm.

       3. The grid structure project is not only an independent individual, but also involves the joint cooperation of some supporting material systems such as walls and roofs. In fact, the solution in this respect is also the fundamental of the current steel structure grid.

       4. Due to the development time of grid processing in China is not too long, whether from the technical level or from the related investment in Grid Engineering, it is far behind the developed countries in the West.
