Aluminum gates can be used for either indoors or outdoor areas. Most of the aluminum gates are made from a light weight rust-proof composite of aluminum and stainless-steel. Many of them can be used for both indoor and outdoor purposes. Many of these gates also have extensions available depending upon the model purchased. Many of these gates also have a powder coating that results in a long lasting and easy to clean surface.
The photo shows an example of an outdoor gate. These gates work well for stairways as they will mount at angles up to 30 degrees. Many dogs that are in their senior years have a difficult time navagating stairways so a gate may be needed for the dog’s protection if the dog is unstable when he walks, if he does attempt to navigate the stairs he could fall and injure himself badly and that is something you definately don’t want to happen with your best friend and companion. This will also reduce your worries about your senior pet as you know he will be safe in your yard for several hours as long as he has fresh water and the weather is mild. So if you do need to leave him outside for awhile and he enjoys it then there are no worries!
