Wrought iron hardware comes in a variety of strengths and uses. When installing a wrought iron decorative gate hinge, it is important that the hinge meets the needs of the gate. The hinge must be strong enough to hold the gate onto its post in addition to being strong enough to withstand constant use. Hanging a fence gate with decorative hinges is not much different from hanging other types of gate hinges.
Check which way the gate will swing, either in or out, to position the hinges in the right direction.
Plan the placement of the hinges. One hinge should go near the top of the post and one on the bottom to evenly distribute gate weight. Allow 2 to 3 inches (5 to 7.5 cm) of space under the gate so it can clear the ground below it during all seasons.
Hold the hinge in place and use a level to make sure the hinge is level. Mark the location of the screw holes with a pencil.
Screw the hinge into place on the post using the pencil marks as a guide. Hold the gate up to the post hinges and mark with a pencil the placement of the hinge on the gate. Use a level when marking the placement of the hinge.
Screw the hinges onto the gate where the pencil marks indicate. Lift the gate with hinges attached and screw it onto the post. Screw the top hinge on first, not completely but enough to hold it in place. Have someone assist you by holding the gate level. Screw the bottom hinge on, but not completely. Make sure one more time that the gate is level. Go back and completely tighten the top and bottom hinge screws.
