Coextrusion WPC Wood Plastic Composite Fence Panels UV Resistant Waterproof

Product Specification

UV resistant waterproof moldproof coextrusion WPC fence

Product Summary

This professional solution highlights the UV resistant, waterproof, and moldproof coextrusion WPC fence engineered for harsh outdoor climates. By utilizing a 360-degree co-extruded polymer shield, it completely blocks moisture penetration and effectively reflects intense solar radiation. This overview directly tackles industry headaches like fading, cracking, and rotting, offering a long-lasting, premium architectural framing solution for regions prone to heavy rain, high humidity, and prolonged sun exposure.

Product Features

• Advanced UV Resistance & Color Stability

•  Our second-generation coextrusion fence incorporates premium UV inhibitors within its outer polymer shield. Tested under accelerated weathering chambers, it resists color degradation and chalking under intense sunlight, ensuring your estate boundary looks vibrant and new for decades. 

• 100% Waterproof Outer Shield 

•  The outer engineering-grade polymer cap is completely non-porous and hydrophobic. It forms an impenetrable barrier that keeps rainwater, morning dew, and groundwater away from the internal composite core, preventing structural swelling or weakening. 

• Extreme Mold and Rot Prevention

•  Traditional fences easily breed black mold in humid conditions. Due to the seamless capped technology, bacteria and fungal spores cannot find a foothold to grow. The fence remains 100% moldproof and rotproof, making it ideal for lakeside, seaside, or garden perimeter setups.

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 UV resistant technology prevent the coextrusion WPC fence from fading?

A1: The outer polymer layer is enriched with high-density UV stabilizers and light-blocking pigments. These components absorb and dissipate harmful ultraviolet radiation before it can break down the color molecules, providing a level of colorfastness that standard wood or Gen-1 WPC cannot match. 

Q2: Can this waterproof WPC fence be used in coastal or high-humidity areas?

A2: Absolutely. Since the 360-degree shield is completely waterproof and saltwater resistant, it will not rust, erode, or absorb coastal moisture. It successfully eliminates the warping and salt-corrosion issues that usually destroy traditional iron or natural wood fences in coastal environments. 

Q3: Why is a moldproof WPC fence better than treated timber for family backyards?

A3: Treated timber requires toxic chemical sealants to fight mold, which can leach into the soil. Our coextrusion fence achieves its 100% moldproof status purely through its physical, non-porous polymer shield. It requires zero chemical maintenance, making it completely safe for children, pets, and backyard eco-systems. 

Q4: Will severe winter freezes affect the waterproof integrity of this fence? A4: No. Because the fence is entirely waterproof, there is no moisture trapped inside the material. Without internal water, there is no risk of the freeze-thaw cycle causing internal ice expansion, which is the primary cause of cracking and splitting in traditional timber and budget composites.
