Balcony, terrace, and stairway guards and railings
Critical itemPer EN 1991-1-1 and national building regulations, guards (balustrades) are required on all elevated walking surfaces. Minimum guard heights vary by country but generally require 1000 mm (1100 mm in Germany per DIN 18065 for drops over 12 m, 1100 mm in France per NF P01-012 for drops over 1 m). Openings in guards must not allow passage of a 100 mm sphere (child safety, per most national codes). Horizontal loads on guards must resist 0.5–1.0 kN/m per EN 1991-1-1 Table 6.12. Insurers flag non-compliant or deteriorated guards as significant liability.
