LARGE DRIVEWAY GATE WITH FENCE PANELS

Here's a popular configuration with a large driveway gate and fence panels on each side.
 
If your double swing gate width is 12 feet or less, you can use residential fence panels with a residential double swing gate.  You can use 2" x 2" or 2.5" x 2.5" Gate Posts for residential double swing gates up to 12 feet wide
 
If your double swing driveway gate width is 14 - 16 feet wide, you can use residential fence panels but you must upgrade to a commercial double swing gate.  Or, you can simply use commercial grade for everything (fence panels and gate).  You can use 4" x 4" Gate Posts for commercial double swing gates up to 16 feet wide.
 
If your double swing driveway gate is 18 - 28 feet, you can use residential fence panels, but you must upgrade to an industrial double swing gate.  Or, you can simply use industrial grade for everything (fence panels and gate).  You MUST use 6" x 6" Steel Posts for industrial double swing gates 20 feet wide or wider.
