Privacy Lattice Trellis Flow Outdoor WPC Garden Fence Composite Fence Board

Product Specification

Privacy-Lattice & Trellis-Flow Outdoor WPC Garden Fence

Product Summary

This specification details a first-generation premium criss-cross lattice and trellis fencing system engineered to blend classic European garden elegance with organic horticultural functionality. Extruded as a high-density, single-layer composite matrix rich in premium wood flour and eco-polymers, it delivers an ultra-matte, authentic timber touch while permanently eliminating the yellowing, cracking, and sagging common to cheap plastic screens. The precision-engineered geometric mesh pattern achieves an ideal architectural harmony—allowing dappled sunlight and fresh air to filter through while maintaining an elegant privacy boundary. Serving as a robust structural framework for climbing ivy, vines, and roses, it provides the ultimate decorative perimeter upgrade for high-end residential courtyards and luxury estate gardens.

About this Product

• Dual-Function Lattice Trellis 

  • Designed with a structural criss-cross diamond or square mesh, this outdoor WPC fence provides an ideal vertical support system for climbing roses and jasmine while creating an elegant garden backdrop.

• Micro-Dappled Sunlight & Air Flow

  • The open-mesh geometry allows soft, filtered daylight and refreshing summer breezes to flow freely into the backyard, avoiding the dark, stagnant, and claustrophobic feel of massive concrete walls.

• Architectural Adaptability & Sizing

  • Built within a sturdy perimeter framing channel, the modular lattice inserts can be easily trimmed down on-site with standard woodworking tools to fit custom architectural framing spans.

• Uniform Matte Through-Body Pigment

  • The single-layer un-capped core is deeply infused with UV-stable pigments and anti-fungal agents, ensuring that direct abrasion from scratching vines or plant moisture will never trigger peeling.

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: Will the weight of heavy climbing plants, like wisteria or heavy ivy, cause this WPC lattice fence to sag or bend?

A1: No, it will not. Unlike thin plastic PVC lattices that easily warp and buckle under organic plant loads, this first-generation WPC profile possesses high flexural stiffness. When locked securely inside our heavy-duty WPC perimeter framing channels, the mesh structure distributes gravity weight evenly, remaining rigid and square even under a dense wall of foliage.

Q2: Does the criss-cross mesh design make the fence fragile against localized baseball or soccer ball impacts?

A2: Not at all. Every intersection of our lattice framework is fused together during extrusion or mechanically secured with high-tolerance interlocking tracks. The solid, fiber-reinforced core provides exceptional shear strength and impact elasticity, meaning it can easily absorb daily backyard chaos like a stray soccer ball or a pet running into it without snapping the bars.

Q3: How much visibility does this trellis fence block? Can people on the sidewalk see directly into my garden?

A3: It offers a highly effective "visual confusion" barrier. While it is an open-mesh product, the standard mesh opening size creates a strong optical depth that naturally blurs incoming lines of sight. When viewed from a distance on a sidewalk, observers see the beautiful geometric pattern and shadows rather than the clear details inside your yard, providing sophisticated semi-privacy.

Q4: Plant moisture and soil trapped in the lattice joints usually cause mold. How do I maintain this fence over time?

A4: Maintenance is remarkably simple. Natural wood lattices rot in the joints because trapped water cannot dry out, but our WPC matrix blocks water absorption. If organic debris or green moss accumulates in the corners from plant growth, you can simply spray the lattice with a standard garden hose or mild domestic algae-wash once a year, and it will look perfectly pristine without needing any scraping or painting.
