There is always a reason for wanting a decorative metal gate. Maybe it is just to give you a bit more security, or a lot of security. It may be to keep your pets safely in your garden away from traffic and to avoid theft. You may want railings to define your property boundry or to stop leaflet delivery people crossing your grass. There is always the fact that you like the look of them. Whatever your reasons, choose wisely, they should be with you for a long time.
