What went wrong
Underspec'd wire, every time
When we look at a sagging perimeter, the problem is almost always the same: mesh gauge that wasn't matched to the job. Mesh gauge is not cosmetic. A 9-gauge wire is significantly thicker and stronger than 11-gauge wire.
What we check
Gauge, tension bands and boundary
For a commercial parking lot perimeter in Van Nuys, where vehicles back up close and wind channels between buildings, 9-gauge galvanized fabric with a 1-5/8 inch top rail is the correct starting point. Tension bands must be torqued at correct intervals: over-torqued and the fabric distorts, under-torqued and the perimeter loosens over time.
What holds up
A fence that stays at spec
For residential jobs in tighter neighborhoods, we run a full boundary check before setting posts. Property lines in dense areas like Panorama City are frequently within inches of where a homeowner thinks the line sits. We confirm post spacing against the actual boundary, not a rough estimate.
