Horizontal wires and slats may be suitable for some balcony balustrades, but their design needs particular care where children may be present. Horizontal elements can create footholds and make climbing easier. The overall construction and applicable local safety requirements determine whether a design is suitable.
Horizontal slats should also be assessed for possible footholds, and gaps must be appropriate for the safety requirements of the location. Planters and furniture next to a balustrade can also make it easier to climb. Glass or vertical bars are often more appropriate where children are present. On a ground-level patio, horizontal lines may be a practical design choice.
