A complete fiberglass security fencing system consists of interlocking pultruded panels and square‑tube posts, all fabricated from the same corrosion‑resistant resin. The panels carry a smooth, snag‑free surface on the outside and optional grit‑stippled inner face for added rigidity. Because the material is non‑conductive and non‑magnetic, it generally eliminates the bonding and grounding calculations that steel fencing demands. In a live switchyard, that property helps remove a pathway for induced currents to travel outside the designated ground grid—an outcome safety engineers commonly value.
For industrial FRP fences in coastal or chemical storage areas, the value proposition shifts to lifecycle. Salt mist and chlorine vapour typically attack galvanised coatings within 18–24 months, leaving staining on concrete plinths and rust streaks on panels. FRP fencing in the same location generally stays visually unchanged, with no repainting or sacrificial anode replacement. A washdown with the site hose is commonly the only recurring maintenance, and the material's dielectric properties typically remain unaffected by UV exposure. Electrical properties are commonly evaluated under ASTM D149.
Panel construction uses pultruded square‑tube framing with internal mesh or solid infill, integrally bonded. Standard panel size is 2.4 m wide × 1.8 m high, with custom heights available. Post sections are typically square tube 65 × 65 mm with 4.8 mm wall thickness, spaced at 2.4 m centre‑to‑centre to match panel width. Weight is approximately 12 kg per linear metre of panel. Resin systems include isophthalic polyester as standard, with vinyl ester available for severe chemical exposure. Fire performance generally achieves a flame spread index ≤ 25 when tested per ASTM E‑84. Installation uses 316 stainless steel base‑plate anchors and panel‑to‑post clips—no hot work, no field cutting needed for straight runs. Panels can be trimmed with a carbide blade where compound angles or existing structures require it.

Proven in Field
"We switched from galvanised steel to FRP fencing around our substation perimeter after the grounding audit flagged recurring corrosion at post bases. The new fence has been in place for five years with no recurring maintenance, and the RF transparency solved our radio‑comms dead spots near the compound."
