Handrail (5% spare)4.20 m
Posts (1.2 m spacing)5 posts

Calculation

  1. 1GB 50096-2011: vertical bar clear gap ≤ 110 mm, never exceed it
  2. 2Bars = ⌈4×1000 ÷ (20+110)⌉ = 31
  3. 3Handrail = 4 × 1.05 = 4.20 m
  4. 4Posts = ⌈4 ÷ 1.2⌉ + 1 = 5
  • GB 50096-2011 (mandatory): bar clear gap ≤ 0.11 m — small children must not squeeze through.
  • Min guard height: ≥1.05 m for floors ≤6; ≥1.10 m for floors ≥7, measured from the climbable surface.
  • Stair handrails ≥0.90 m; ≥1.05 m for horizontal runs longer than 0.50 m.
  • Bars that can hold flower pots need anti-fall measures (mandatory clause).
  • Post spacing of 1.2 m is typical for DIY builds; 1.0-1.5 m per brand spec is acceptable.
  • Two horizontal rails (top handrail + bottom rail) are standard for zinc-steel / wrought-iron fencing.
