Jiulong Hot Dipped Galvanized Handrail Ball Joint Type Stanchion
Industrial stairs are not like the regular stairs. They have to be designed and fabricated considering the location of the staircase and its utility. There are certain set guidelines and government norms which have to be followed while manufacturing industrial stairs. Different types of industrial stairs have different steel handrail options
Guardrail is to provide edge protection at the edge of a floor, platform or walkway. Handrail is rail that provides a handhold on a platform, walkway, stairway or step ladder. Guardrail can be designed to be suitable for use as a handrail.
NJMM is available in component form, eg, Stanchions, bends, pipe and kick-plate or can be supplied in fully fabricated panels for even quicker site installation.
NJMM HANDRAIL can be supplied in panels and manufactured to suite your exact requirements.
