Choosing a hinge for your swing gate is important since it will always be moving when the gate opens and closes. Self-closing or non-self closings hinges are available for wood, steel, aluminum and chain link gates. These hinges are offered in polymer, aluminum, steel or stainless steel and must be chosen according to the weight of the gate. Truclose and Sureclose hinges are commonly used for pool gate safety since they are self closing. Steel and/or stainless steel hinges are used more for larger driveway and estate gates since these gates weigh more than the normal pool or garden gate. The selection of hinges AIDI offers can be welded or mechanically fastened to the gate frame and gate post.
