In the site installation, the steel structure components normally adopt welded connection and bolt connection. In order to meet the bolt connection requirements, the manufacture needs to make holes in the corresponding positions on the surface of the steel components. And the holes' position and dimension must meet the specification requirements. If the installation has trouble of unqualified holes on the site, it will needs the manufacturing rework. It will cause the greater economic losses.
