The main differences are appearance, sightlines and how easy the balustrade is to climb. Horizontal bars create long, contemporary lines, whereas vertical bars give a more traditional pattern without the same step-like arrangement. Horizontal bars can provide footholds and may be easier to climb.
Where young children may be present and the balustrade protects against falls, vertical bars are often the more suitable choice. On a ground-level patio, where the balustrade mainly defines the space, horizontal bars can be an attractive design option. Both aluminium and stainless steel balustrades are available with bar infill.
