Coextrusion WPC Fence Termite Proof 100x20mm WPC Composite Fencing

Product Specification

100mm*20mm Termite proof cost effective coextrusion WPC fence

Product Summary

This premium layout introduces the termite proof, cost effective coextrusion WPC fence 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. This overview directly tackles the industry headaches of insect destruction and soaring upkeep costs, delivering a highly profitable outdoor fencing solution.

About this Product

• 100% Termite and Insect Proof Barrier

• The outer co-extruded shield creates an impenetrable polymer barrier that wraps every millimeter of the inner core. Because insects and wood-borers cannot bite through or digest this high-density engineering plastic, the fence remains safe from the underground termite colonies that ruin natural timber. 

• 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 to 30 years and zero expenses required for chemical sealing, sanding, or staining, it cuts out hundreds of dollars in annual maintenance fees, lowering your total cost of ownership. 

• No Replacement Maintenance Costs

• Traditional wooden boundaries often rot or get structurally hollowed out by pests within 5 to 7 years, forcing expensive replacements. This cost effective composite fence retains its strength and beauty decade after decade, ensuring your property value appreciates without unexpected repair bills.

How to Install

Method 1: In-Ground / Dig-In Installation

[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; otherwise, the fence boards will not fit into the post slots.

2. Digging Post Holes: Dig foundation holes at the marked locations. Standard requirement: Hole diameter is generally 300 mm, with a depth of 500 mm - 600 mm (in cold regions, the depth must extend below the frost line).

3. Setting Posts and Pouring Concrete: Insert the WPC posts (or composite posts with internal steel/aluminum reinforcements) into the holes. Pour in mixed concrete (Grade C20 or above). Key Step: Use a spirit level to repeatedly check and adjust the post in two vertical directions to ensure it is 100% plumb.

4. Curing and Waiting: Temporarily secure the leveled posts with bracing timber and allow the concrete to cure. Typically, a waiting period of 24 to 48 hours is required to ensure the concrete has fully hardened before proceeding with board assembly.

Method 2: Bolt-Down with Base Plate

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

1. Positioning and Marking: Align the string line on the hardened ground. Determine the exact position of the post base plates based on the net length of the fence board (e.g., 1750 mm plus the post slot depth). Mark the drill holes through the base plate using a marker.

2. Drilling: Use an impact drill equipped with a drill bit that matches the expansion anchors (usually 12 mm or 14 mm in diameter). Drill vertically into the concrete to a depth of 80 mm - 100 mm. Clean out all dust and debris from the holes.

3. Installing and Securing the Metal Base: Align the galvanized steel or aluminum post support base over the drilled holes. Insert the metal expansion anchor bolts or chemical anchors, and tighten them securely using a socket wrench to anchor the base firmly to the concrete.

4. Sleeving the WPC Post: Slide the outer hollow WPC post sleeve from top to bottom over the fixed metal base plate, then lock the inner and outer layers together at the bottom using self-tapping screws.

FAQ

Q1: How does the 360 capped technology make a coextrusion fence completely termite proof?

A1: Termites target natural wood to feed on cellulose. Our second-generation coextrusion fence encapsulates the wood fibers beneath a tough, inedible engineering-grade polymer shield. Termites cannot sense or penetrate this outer barrier, leaving the internal structure completely safe and untouched. 

Q2: Why is this premium coextrusion WPC fence described as a cost effective option?

A2: It is cost effective because it eliminates the ongoing "hidden costs" of fencing. A cheap wood fence requires expensive paints, sealants, and termite sprays every 2 years, plus full replacement in a decade. Our fence requires zero maintenance spending and lasts 3 times longer, breaking even within just a few years.

Q3: Can termites tunnel up through the post or base connections of this WPC fence?

A3: No. When combined with our heavy-duty rust-proof aluminum posts and composite brackets, there are no organic entry paths for pests. The entire perimeter system is engineered from non-organic surfaces at ground level, preventing insects from climbing or nesting inside the structural joints. 

Q4: Will the termite proof additives inside the shield wear out and lose efficacy after many years?

A4: No, because we do not rely on temporary chemical sprays. The termite proof property comes from the physical density and hardness of the polymer shell itself. Since it is a structural barrier extruded under extreme heat, it will never wash away or degrade, protecting your garden for its entire lifespan.
