Either way, the stair railing needs to be installed on site.

The more traditional method of installing a guardrail is to drill holes in the stair treads, wedge expansion screws, and then fasten the guardrail bars into the holes to secure the guardrail. Although there are currently prefabricated stairway plates in which holes are reserved or in which internally threaded holes are pre-embedded, thereby reducing the mechanical operations of drilling holes in the field, there are problems in the field assembly, for example, one of the existing guardrail post installations is designed to have a threaded rod at the end of the post, which is drilled into the pre-embedded internally threaded hole in the stairway plate at the installation site, and this way has the following problems: when the threaded rod and threaded hole are fully tightened, the positioning of the upright in the circumferential direction of rotation may be inadequate, it is desirable that the parts on the upright for attaching the crossbar be properly positioned for smooth installation of the crossbar, and if the upright is not rotated into position, the crossbar will not be properly installed. In the installation process, in order to settle the installation of horizontal pole, often the screw rod on the pole setting is not screwed with the screw hole or the screw rod is by transition screw in, and this all can influence the steadiness of guardrail.

Further, after the vertical rod is fixed, the cross rod needs to be assembled, the installation of the cross rod is expected to be simple and easy, but the installation of the cross rod is too complex due to the design of the guardrail in the prior art, on-site drilling is needed, more bolts are needed, the installation workload is large, the installation effect depends on the operation fidelity of workers, and the uniformity after installation is poor.
