| Railing function and purpose | Height (MM) |
| Handrail height of indoor stairs | 900mm |
| Balconies, verandahs, inner patios and roof railing height | Below 6 layers (multi-layer) ≥ 1050mm,7 layers above (middle and high-rise) ≥1100mm |
| When the railing length of the horizontal section of the stairs is ≥500MM, the height of the handrail | ≥1050mm |
| The stairs and ramps of elderly buildings should have two consecutive levels of railings, and the height of the upper and lower handrails | 900mm and 650mm |
| Elderly building balcony railing height, roof wall guardrail height | ≥1100mm |
| Children’s handrail height should be set on the side of the wall of the nursery building stairs | ≤600mm |
| The clear height of the guardrail of the nursery building balcony and roof terrace | ≥1200mm |
