Which type of guard would have to support a higher load?

Horizontal guards are designed to support a higher load because they need to account for the weight and forces applied in a horizontal direction, particularly from people leaning or pushing against the barrier. This type of guard is often found in scenarios where it provides protection along edges, such as stairways or decks, where individuals might exert force in multiple directions.

The structural demands placed on horizontal guards require them to be built to handle not just the weight of individuals leaning against them but also potential dynamic loads, like sudden shifts in weight or force. Therefore, the materials and design must be robust enough to meet safety standards and ensure stability under various conditions.

In contrast, other types of guards like vertical guards, railing guards, or balcony guards may have specific roles and load requirements that differ from those of horizontal guards. They have varied design considerations and load paths that do not generally necessitate the same level of horizontal load bearing as horizontal guards.
