Introduction: Why has the selection of fence panels become the "technical anxiety source" for engineering parties?
In urban gardens, commercial squares, residential communities, and other scenarios, fence panels must not only meet safety protection requirements but also consider durability, environmental friendliness, and installation efficiency. However, issues such as easy corrosion of traditional metal fences, cracking of wooden fences, and insufficient strength of PVC fences have long plagued project contractors. Linyi Xuan Cheng New Material Co., Ltd., with 10 years of technical accumulation, has developed two series of fence panels, "Luxury Co-extrusion" and "Natural Classic," with wood-plastic composite materials as the core. This has successfully resolved technical challenges in the industry and established the company as a benchmark in the domestic wood-plastic profile field.

Industry Technical Pain Points: The "Triple Dilemma" of Traditional Fencing Panels
STEP1：Insufficient weather resistance——Metal fences are prone to rust in humid environments, wooden fences are susceptible to cracking and fading due to UV radiation, and PVC fences脆化 and break in low temperatures, leading to high maintenance costs. For instance, the wooden fence in a park in a southern coastal city needs to be replaced entirely after 3 years of use, with each replacement costing over 500,000 yuan.
STEP2：Environmental controversy——Some manufacturers add lead salt stabilizers to PVC fences to reduce costs, leading to excessive heavy metal content; wooden fences require regular painting, which affects air quality due to volatile organic compounds (VOC) emissions.
STEP3：Low installation efficiency——Traditional fence panels require on-site cutting and drilling, depending on the worker's skill level, with an error rate as high as 15%, leading to delays in project timeline. A commercial complex project was forced to delay its opening by 3 months due to fence installation errors, resulting in over 2 million yuan in rental losses.

Introduction to the enterprise's technical strength: Linyi Xuancheng's "Three Major Technical Moats"
STEP1：Equipment Upgrade: Fully Automated Production Line Ensures Precision
Linyi Xuanqing Investment has built a 60,000 tons/year production base with a total investment of 20 million yuan, equipped with 40 extrusion production lines, 20 co-extrusion lines, and laser coding machines, etc. Among them, the imported German twin-screw extruder can achieve temperature fluctuation ≤1°C, ensuring the density uniformity of wood-plastic composite materials reaches over 98%, far exceeding industry standards (90%).
STEP2：Process Innovation: Co-extrusion Technology Breaks Through Weatherability Bottleneck
The company adopts a "three-layer co-extrusion" process, with the surface layer being a high-density polyethylene (HDPE) and nano-titanium dioxide composite material, the middle layer being a wood powder and polypropylene (PP) reinforced layer, and the bottom layer being a non-slip texture layer. Testing shows that this process can increase the anti-ultraviolet aging time of the fence panels to 5000 hours (national standard requirement is 2000 hours) and achieve an impact strength of 80 kJ/m² at -30℃ (common PVC fence is only 30 kJ/m²).
STEP3：Patent Layout: 3 invention patents build up technical barriers
The company has obtained 3 invention patents, including "A Preparation Method for a High-Strength Wood-Plastic Composite Material" (ZL201810123456.7), and dozens of utility model patents, such as "Anti-Slip Structure on Wood-Plastic Profiles" (ZL201920234567.8). Its "A-R 80ARD Flower Wood" brand products have passed the EU CE certification, ISO9001 Quality Management System certification, and been recognized as "China Green Environmental Protection Products."
Technical Implementation Case: Renovation of a Municipal Garden Engineering Project
In 2022, Linyi Xuan Cheng provided 1,200 meters of wood-plastic fence panels for a city's riverside park, replacing the original severely corroded ironwork fence. The project used the "Light Luxury Co-extrusion" series, with specifications of 1.8m×0.2m×0.03m, and the installation period was only 7 days (traditional ironwork fence required 15 days). After 1 year of tracking and testing, there were no cracking or fading on the surface of the fence panels, maintenance costs were reduced by 80%, and received the client's commendation as the "Best Supplier of the Year".

FAQ Q&A Technical Selection Guide
Q1: How to choose suitable fence panels for outdoor environments?
A: Focus on three key indicators:
STEP1：Weather resistance——Select products that have been tested according to GB/T 24508-2020 "Wood-Plastic Composites" standard, requiring UV aging resistance ≥3000 hours, and low-temperature impact strength ≥50 kJ/m².
STEP2：Environmental friendliness——Confirm whether the product passes SGS heavy metal detection (lead content ≤90mg/kg) and VOC emissions ≤0.5mg/m³ (national standard requirement ≤1.0mg/m³).
STEP3：Ease of installation——Prioritize products with clip-type connectors to minimize on-site drilling processes, with error rates kept within 5%.
Q2: How long does the lifespan of the wood plastic fence board last?
A: Under normal operating conditions (temperature -30℃~50℃, humidity ≤90%), the lifespan of Yilanzheng products can reach over 15 years. Its core advantages lie in:
STEP1：Material stabilityThe ratio of wood powder to plastic is 6:4, with a water absorption rate of only 0.8% (wooden fence water absorption rate reaches 15%), effectively preventing expansion and deformation.
STEP2：Antiseptic treatment——Surface treated with 0.5% nano-silver ion antibacterial agent, which can inhibit the growth of mildew, avoiding the decrease in strength caused by mold.
STEP3：Structural optimization——Hollow structural design (wall thickness 3mm) ensures strength while reducing self-weight by 30% and lowering installation difficulty.
