Frequently Asked Questions

What gauge wire is required for commercial chain link fencing in Texas?

Commercial and industrial security fencing requires 9-gauge or 6-gauge galvanized steel mesh (or 9-gauge core with vinyl coating). Standard residential 11.5-gauge wire is too thin and easily cut or pushed through by intruders.

What pipe schedule is used for commercial fence posts?

Commercial applications specify Schedule 40 galvanized steel pipe (minimum 2-3/8" OD for line posts, 2-7/8" or 3-1/2" OD for terminal and corner posts). Schedule 20 or light tubing will bend under wind load or automated gate cantilever stresses.

Are barbed wire and razor wire legal on commercial properties in Texas?

Yes, when installed above a minimum height of 6 or 7 feet from grade (depending on local municipal codes in Houston, Dallas, Fort Worth, etc.). Razor ribbon may require specific industrial zoning classifications.
