For swing gates with leafs 12' wide or wider and cantilever gates for openings wider than 16', we recommend steel posts for structural integrity. These durable 4''x4'' posts are available in a variety of lengths and in all five standard Integrity colors, but must be ordered as blank posts. When attaching fence panels to these posts, mounting brackets are a necessity. On rare occasions, customers request even larger 6''x6'' steel posts. This larger size must be special ordered and often cannot be shipped within typical lead times.
