The technical requirements for stair railings mainly include material requirements, structural design requirements, installation requirements and maintenance requirements.
Material requirements
Stair railings should be made of strong and durable materials, common materials include steel, aluminum alloy, stainless steel, etc. These materials need to have sufficient strength and rigidity, and the corrosion resistance should meet the relevant standards to ensure that the railings will not rust or corrode after long-term use.
Structural design requirements
Height requirements:

The railings in public places should not be left empty within a height range of 0.1 meters from the ground.
Clear distance between rods:
The clear distance between railings in ordinary civil buildings should be less than or equal to 0.11 meters.
The net distance between railings in nurseries and kindergartens should be less than or equal to 0.09 meters.
Style requirements:
The railing style should give priority to the standard style to ensure safety and aesthetics.
Installation requirements:
Professional construction: The railing should be installed by professionals to ensure construction quality and safety.
Fixing requirements: The railing should be installed tightly and fixed without looseness or shaking.
Anti-slip requirements: Anti-slip pads should be set at the bottom of the railing column to prevent it from sliding or shaking.
Maintenance requirements: Regular inspection: The railing should be inspected and maintained regularly to ensure its normal use and safety.
Surface coating inspection: The surface coating of the railing should be inspected regularly. If it is damaged or peeled off, it should be repaired or replaced in time.
Cleaning requirements: The railing should be cleaned regularly to keep it clean and tidy, and prevent pollution and long-term accumulation of impurities from affecting its structure and function.
