Have you ever noticed a lot of gates(especially the long and heavy ones) have a wheel attached to the bottom so when you open the gate is can roll on this wheel?
This is only done because the type of hinge they are using is too weak to support the gate on its own or the material used to make the gate is of such heavy and rugged material, for security purposes no hinge will be able to handle that weight.
Most Outdoor Gate Hinges are made of rustproof and rugged metal or alloys like brass, copper or stainless steel.
As these metals not only have strength to your average garden gate but because of its beautiful texture, look and sometimes design, it can add that bit of extra to your gate as it is the first thing anyone sees when entering your property.
So choosing the right gate with the right hinges can also add value to your home.
