The price of fencing is primarily driven by material grade, coating thickness, and structural dimensions. For steel fencing, ensure the use of hot-dipped galvanized steel (ASTM A123) to prevent rust. The wire gauge (e.g., 6-gauge or 8-gauge) and mesh size significantly impact the cost; smaller mesh sizes require more material and offer higher security. For aluminum options, verify the alloy grade (e.g., 6061-T6) for structural integrity. Always check the powder coating thickness (measured in microns), as a high-quality AkzoNobel or Tiger Drylac coating ensures UV resistance and longevity, reducing long-term maintenance costs.
