Superb gate! The paintwork is beautiful and the quality seems to be there, but only time will tell. For now, I am completely satisfied with this lovely gate.

It's a shame that the surveyor didn't plan for a corner return and that the feet of the guardrail cannot take into account the slope of the concrete on which it is installed. Otherwise, nothing to say, we'll see how it goes over time.
