In the whole steel structure, it is important, whether in general or in small details, because it is often the key to the material that we don't care or think it is not important. What quality control points should we pay attention to in engineering? The steel structure of Foshan tells you that:
1. directly affect the quality of installation is the embedment of anchor bolts, whether location, length, elevation or other factors are very important. The same high strength bolt link is also important.
2. welding engineering is an important part in the process of production and installation. The welding methods adopted will be determined according to different heights and angles.
