Iron gates are used for decorative purposes as well as for safety and securing property. Most pillars are built of concrete or brick. For aesthetics, some pillars are iron posts that have been encased in wooden boxes. Because iron gates can be too heavy for one person to lift safely, it is advised to enlist a helper when attaching the gates to the pillars. A third person would be helpful in marking the placements for carriage bolts and screws. There are dozens of hinge styles to choose from, but they basically all work the same.

Skill level:

Things you need

  • 2 sets, 36-inch strap hinges with carriage bolts
  • Electric drill
  • Masonry drill bits
  • 16 galvanised screws, 3/8-inch by 5 inches
  • Screw driver
  • Tape measure
  • Pencil
  • 4 to 6 wooden blocks, 4 by 6 inches

  1. 1

    Open the packages of hinges. Decide on the placement, using one hinge near the top of the gate and the other near the bottom of the gate. With one side of the gate lying on the ground with the inside facing up, place the long side of the hinge on the gate.

    Align the hinges. Trace the outline of the carriage bolt holes. Drill the three holes for the carriage bolts for both hinges.

  3. 3

    Hold the gate upright and place the bolts in the holes, securing them with the nuts and washers that came with the hinge sets. With the gate next to the pillar, support it with the wooden blocks underneath to achieve the proper height. The short side of the hinge will be between the gate and the pillar.

    Open the short side of the hinge against the pillar. Mark the screw holes. Pre-drill the screw holes with a bit slightly smaller than the diameter of the screws. Screw the top hinge into the pillar first, then screw the bottom hinge into the pillar.

    Repeat steps 2 through 4 for the other side of the gate. Have a helper hold the second side of the gate in place in complete alignment with the first side of the gate before marking the screw holes.

Tips and warnings

  • Adjustments can be made if the two sides of the gate do not align perfectly. Galvanised screws are usually included in the hinge kit, but sometimes you may have to buy your own. Larger strap hinges are available if your gate is very heavy. Heavier gates may need three hinges per gate.
  • It is not advised to install heavy gates without a helper.
