Description

Safety railing for construction {SAFETY HANDRAIL FOR BUILDING}

The present invention relates to a construction safety railing for freely changing the protruding direction of a pillar member in the safety railing according to the installation type of the structure.

Typically, when constructing, remodeling, or repairing a building, a steel frame (also called an 'H-Beam') is installed to prevent the collapse of the ground, support a poured foundation wall, or to a steel frame structure. In addition, the steel frame installed as described above is also used as a movement path for workers.
