This premium termite-proof, cost-effective coextrusion WPC fence is engineered for absolute biological protection and long-term asset value. Utilizing a 360-degree dense polymer shield, it completely blocks termites and wood-boring insects from accessing the inner fibers. By eliminating the need for ongoing painting and pest treatments, it offers unmatched lifetime cost savings.

• 100% Termite and Insect Proof Barrier: The outer co-extruded shield creates an impenetrable polymer barrier that wraps every millimeter of the inner core. Insects and wood-borers cannot bite through or digest this high-density engineering plastic, keeping the fence safe from underground termite colonies.
• Highly Cost Effective Lifetime Value: While the initial purchase price is higher than standard timber, its real financial value shines over time. With a lifespan exceeding 25-30 years and zero expenses for chemical sealing, sanding, or staining, it eliminates hundreds of dollars in annual maintenance fees.
• No Replacement Maintenance Costs: Traditional wooden boundaries often rot or get structurally hollowed out by pests within 5-7 years, forcing expensive replacements. This composite fence retains its strength and beauty decade after decade, ensuring property value appreciation without unexpected repair bills.

Applicable Scenario: Soft ground surfaces such as gardens, lawns, soil, or sandy ground. This is the most stable method for outdoor fencing.

1. Measurement, Layout, and Alignment: Stretch a string line according to the standard span of the fence (typically 1.8 m) to mark the exact center point of each post. Precision in spacing is critical.
2. Digging Post Holes: Dig foundation holes at marked locations. Standard requirement: Hole diameter is generally 300 mm, with a depth of 500-600 mm (in cold regions, depth must extend below frost line).
3. Setting Posts and Pouring Concrete: Insert WPC posts into holes. Pour mixed concrete (Grade C20 or above). Use a spirit level to repeatedly check and adjust the post in two vertical directions to ensure 100% plumb.
4. Curing and Waiting: Temporarily secure leveled posts with bracing timber and allow concrete to cure. Typically wait 24-48 hours for concrete to fully harden before board assembly.

Applicable Scenario: Pre-hardened ground surfaces such as concrete slabs, concrete foundations, or brick/stone patios.

1. Positioning and Marking: Align string line on hardened ground. Determine exact position of post base plates based on net length of fence board. Mark drill holes through base plate.
2. Drilling: Use impact drill with drill bit matching expansion anchors (usually 12 mm or 14 mm diameter). Drill vertically into concrete to depth of 80-100 mm. Clean out all dust and debris.
3. Installing and Securing the Metal Base: Align galvanized steel or aluminum post support base over drilled holes. Insert metal expansion anchor bolts or chemical anchors, and tighten securely using socket wrench.
4. Sleeving the WPC Post: Slide outer hollow WPC post sleeve from top to bottom over fixed metal base plate, then lock inner and outer layers together at bottom using self-tapping screws.
