Double-sided Co-extruded Seven-round-hole

As a high-performance wood-plastic profile specially developed for multiple outdoor scenarios, it takes double-sided co-extrusion protection and seven-round-hole mechanical structure as core highlights, balancing protection, stability and economy, suitable for global outdoor building materials market needs.Adopting "base material + double-sided co-extruded protective layer" composite structure: The base material is made of high-density PE as the core, mixed with dried and screened wood powder and anti-aging, UV-resistant, flame-retardant additives, formed by high-temperature melting; 0.6-0.8mm special outdoor weather-resistant layers are co-extruded on both front and back sides, seamlessly bonded to the base material. No formaldehyde or heavy metal release, with indicators better than EU E0 level and US CARB P2 standard, 100% recyclable. Certified by CE, ASTM D7032 and ISO 14001, fully complying with the access requirements of major global markets.

Core Outdoor Features
Dual Structural Advantages, Outstanding Performance: The double-sided co-extruded layer provides 360° protection,
with UV resistance, scratch resistance and stain resistance. The fading rate is ≤5% after 5 years of outdoor exposure, and both sides are universal, adapting to diverse installation needs; the seven-round-hole is mechanically optimized, with bending strength ≥17MPa and impact strength ≥5.0kJ/m² under the 2.6kg/m lightweight design, and the load-bearing capacity is comparable to thick-walled boards. It also features efficient drainage and ventilation, eliminating the problem of rainwater accumulation and aging, with stronger adaptability to humid environments.Extreme Weather Resistance, Long Service Life: Certified by third-party testing, it can withstand extreme temperature differences of -40℃~75℃, and easily resist tropical strong sunlight, cold zone freeze-thaw, coastal salt spray and industrial mild pollution. The outdoor service life is 20-25 years, far exceeding traditional solid wood and ordinary single-sided co-extruded wood-plastic.
Lightweight & Efficient, Convenient Maintenance: With a 2.6kg/m weight design, one worker can carry more than 60 meters at a time, greatly improving construction efficiency; the double-sided co-extruded layer forms a dense protective barrier, fundamentally solving the problems of moth and mildew. Daily maintenance requires no painting or waxing, and it can be kept clean by rinsing with water, significantly reducing the later maintenance cost.
High Cost-Effectiveness, Suitable for Foreign Trade: The 150mm width improves laying efficiency, with only 6.7 meters per square meter; mature technology ensures dimensional accuracy error ≤0.3mm and installation loss <0.5%; lightweight + seven-round-hole structure saves raw materials, making the purchase cost more competitive, while reducing cross-border transportation costs, suitable for foreign trade long-distance transportation needs.
Global Outdoor Application Scenarios
Widely adapting to mid-to-high-end outdoor scenarios around the world, the core application areas include:
1. Public landscape projects: urban central park trails, 5A scenic spot boardwalks, wetland park water-facing platforms, municipal square leisure areas;
2. Commercial outdoor spaces: high-end shopping mall outdoor seating areas, five-star hotel courtyards, chain restaurant terraces, RV camp high-quality floors;
3. High-end residential outdoors: villa courtyards, top-floor terraces, high-end homestay outdoor platforms, private garden trails;
4. Special outdoor scenarios: dock anti-slip trails, yacht club deck auxiliary materials, swimming pool surrounding anti-slip floors, golf course supporting trails, etc.

Standard Installation Method
Adapting to the general installation process of outdoor floors worldwide, the operation is convenient and efficient without professional special equipment:
1. Foundation pretreatment: The outdoor ground needs to be leveled and compacted, with a 2%-3% drainage slope reserved. For soft soil foundations, a 10-15cm gravel cushion and C15 concrete leveling are required;
2. Keel laying: Use outdoor-specific anti-corrosion wood keels (moisture content ≤15%) or hot-dip galvanized steel keels, fixed at a spacing of 40-45cm. The keel level error is ≤2mm/m, and the top surface must be consistent with the drainage slope;
3. Board installation: Choose either side to face up according to scenario needs, connect with keels through seven-round holes using special stainless steel buckles or self-tapping screws, and reserve 3-5mm expansion joints between boards to cope with temperature changes;
4. Final acceptance: After installation, clean the surface debris, check the firmness of the boards, uniformity of gaps and flatness, and put them into use if there is no looseness, warping or height difference.

Environmental Advantages
The product uses recycled plastics and natural wood fibers as raw materials, reducing the consumption of primary resources and reducing white pollution and deforestation. The production process is environmentally friendly with no harmful gas or substance emissions. After being discarded, it can also be recycled and reused, conforming to the sustainable development concept of environmental protection and contributing to green buildings and the ecological environment.
