Project name：Staircase renovation works
Project introduction：
The installation of railings should be carried out in accordance with the requirements and the sequence of construction ink line from the starting point up. The vertical poles at both ends of the platform at the start of the stairs should be installed first, and the installation method should be fixed by bolts. During welding construction, the electrode should be of the same material as the base material. When installing, the vertical rod and the embedded part will be temporarily fixed by spot welding. After elevation and vertical correction, the welding is firm.

The installation of railings should be carried out in accordance with the requirements and the sequence of construction ink line from the starting point up. The vertical poles at both ends of the platform at the start of the stairs should be installed first, and the installation method should be fixed by bolts. During welding construction, the electrode should be of the same material as the base material. When installing, the vertical rod and the embedded part will be temporarily fixed by spot welding. After elevation and vertical correction, the welding is firm.
When bolted connection is adopted, the holes on the metal plate at the bottom of the vertical rod should be processed into waist round holes, in case the location of the expansion bolt is inconsistent, and minor adjustment can be made during installation. During construction, at the base of the erection pole, after drilling into the expansion bolt with an electric drill, connect the erection pole and fix it slightly. When the installation elevation is wrong, adjust it with a thin metal gasket, and tighten the nut after correcting the vertical and elevation.
After the erection of both ends of the vertical rod, the pull line with the same way to install the rest of the vertical rod. Vertical rod installation must be firm, not loose. Vertical rod welding and bolt connection parts, after installation, should be anticorrosive treatment. Stair handrail installation, generally welded installation except special size.
