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.
3. rust prevention and coating engineering in the whole project, it has a great relationship with the maintenance fee in the future, so a good rust proof coating will save more maintenance costs.
Foshan steel structure believes that when installing, there must be professional staff to conduct testing and command, so as to avoid more mistakes.
