A solid leaf acts like a sail. In a strong gust it can push against the operator, trip the obstruction setting or, in the worst case, bend the arm. Louvred or slatted leaves catch less wind, and heavier operators with an electric lock hold a closed gate steady.
If your gate faces open ground or a gap between buildings, mention it on the site visit. Qasar Al Neil Automatic Doors can choose an operator rated for the leaf size and set the force limits so wind alone does not stop the gate.
