| Hot-Dip Galvanized Steel | Chain-link fencing, livestock fencing, perimeter security, highways and construction sites | Common outside diameters: 38–76 mm Wall thickness: 1.5–3.5 mm | High structural strength; suitable for moderate to heavy wind and impact loads | Approximately 15–40 years, depending on zinc coating and environment | Strong, recyclable, widely available and suitable for permanent installations | Zinc coating mass or thickness, steel grade, tube wall thickness, weld quality and drainage design |
| Galvanized Steel with Powder Coating | Residential fencing, commercial properties, schools, parks and decorative metal fencing | Common outside diameters: 40–100 mm Wall thickness: 1.5–4.0 mm | Good strength with an additional decorative and protective surface layer | Approximately 10–30 years, influenced by pretreatment, coating thickness and UV exposure | Available in many colors; improved appearance and resistance to abrasion and weathering | Surface pretreatment, powder thickness, adhesion, color stability and repair method for scratches |
| Aluminum | Decorative fencing, coastal properties, gardens, balconies and lightweight temporary barriers | Common outside diameters: 32–76 mm Wall thickness: 1.5–3.0 mm | Lightweight with good natural corrosion resistance; lower strength than structural steel | Approximately 20–40 years in suitable conditions | Easy to handle, resistant to rusting and suitable for humid or coastal locations | Alloy and temper, profile stiffness, fastener compatibility and protection against galvanic corrosion |
| uPVC / Vinyl | Privacy fencing, residential gardens, pool surrounds and low-maintenance landscaping | Common post sizes: 80 × 80 mm to 150 × 150 mm Wall thickness: commonly 2–5 mm | Good moisture resistance; limited resistance to high impact, heat and strong wind without reinforcement | Approximately 15–30 years, depending on UV stabilizers and climate | Does not rust or rot; low maintenance and easy to clean | UV resistance, impact strength, thermal expansion, internal reinforcement and temperature rating |
| Precast Concrete | High-security boundaries, agricultural fencing, infrastructure projects and permanent heavy-duty installations | Common section sizes: 100 × 100 mm to 150 × 150 mm Typical lengths: 1.8–3.0 m | High compression strength and excellent resistance to fire, rot and termites | Approximately 30–60 years or more with suitable concrete quality and drainage | Very durable, rigid and resistant to biological attack | Concrete strength class, reinforcement, freeze-thaw resistance, lifting points and transport damage |
| Pressure-Treated Wood | Rural fencing, farms, landscaping, horse paddocks and traditional timber boundaries | Common cross-sections: 75 × 75 mm to 150 × 150 mm Typical lengths: 1.8–3.6 m | Good impact absorption and simple field installation; performance varies by wood species and treatment | Approximately 10–25 years in ground-contact use when properly treated | Natural appearance, easy to cut and suitable for irregular terrain | Treatment penetration and retention, ground-contact rating, moisture content, end sealing and local regulations |
| FRP / Fiberglass Composite | Chemical plants, wastewater facilities, coastal sites, utilities and electrically sensitive areas | Common outside diameters: 40–100 mm Wall thickness: 3–8 mm | High corrosion resistance, low electrical conductivity and good strength-to-weight ratio | Approximately 20–40 years, depending on resin system, UV exposure and load conditions | Lightweight, nonconductive and suitable for aggressive chemical environments | Resin type, UV protection, fiber orientation, fire rating, connection details and load calculations |
