WPC Decking Manufacturer and Supplier
Haining Yunxi New Material Technology Co., Ltd. is a China-based WPC Decking manufacturer and supplier with two factories covering nearly 20,000 square meters. We focus on the independent research, development, and production of wood-plastic composite decking, serving residential, commercial, and infrastructure projects across more than ten countries. Our range includes both hollow and solid WPC decking profiles, engineered for outdoor durability, low maintenance, and consistent color retention.
As a direct factory, we control the entire production process—from raw material selection to extrusion and surface finishing. This allows us to offer competitive pricing, custom profiles, and reliable quality assurance for projects of any scale.
Our WPC Decking Range
We supply two main product lines, each designed for specific structural and aesthetic requirements. Both are manufactured with a wood-plastic composite formula that combines recycled wood fiber and thermoplastic resin, offering the look of natural wood with superior resistance to moisture, rot, and insects.
| Product Type |
Key Features |
Typical Applications |
| WPC Hollow Decking |
Lightweight, cost-effective, multi-chamber structure for strength and ventilation |
Residential patios, balconies, garden walkways, pool surrounds |
| WPC Solid Decking |
Dense, heavy-duty construction with high load-bearing capacity |
Commercial boardwalks, public parks, marina decks, high-traffic areas |
Within these categories, we offer various surface finishes, including wood grain embossing and co-extrusion capping for enhanced UV and stain resistance. Our product lineup includes models like the Co-extrusion WPC hollow decking RBCD13922 and the WPC solid decking SCD-YX13723, each available in multiple lengths and colors.
Application Fit and Material Considerations
WPC decking is an alternative to traditional timber for outdoor flooring. Our profiles are suitable for installations over joists on concrete slabs, rooftops, or elevated structures. The material’s inherent moisture resistance makes it ideal for climates with high humidity, rain, or coastal salt exposure.
- Hollow decking is lighter, reducing substructure load, and its internal chambers allow air circulation that helps prevent heat buildup and moisture trapping.
- Solid decking offers higher impact resistance and is recommended for areas with heavy foot traffic or where furniture and fixtures are placed directly on the deck.
We can adjust the wood-to-plastic ratio and additives to meet specific performance requirements, such as increased slip resistance or enhanced UV stability. For projects near water or in freeze-thaw environments, we recommend solid profiles with capped surfaces for maximum longevity.
Critical Specifications and Performance
Our WPC decking is produced to meet international standards for dimensional stability, flexural strength, and weatherability. Key parameters we control during manufacturing include:
- Density: typically 0.55–0.65 g/cm³ for hollow, 0.7–0.85 g/cm³ for solid
- Water absorption: less than 1% after 24-hour immersion
- Modulus of elasticity: above 1800 MPa, ensuring minimal deflection under load
- Surface hardness: 2–5 times that of natural wood, resisting scratches and indentation
We perform in-house testing for color fastness, impact resistance, and screw-holding strength. For large orders, we can provide third-party test reports upon request.
Configuration and Customization
We understand that each project has unique dimensions and design requirements. Our engineering team works with you to customize profile geometry, length, color, and surface texture. We can produce decking boards in standard widths (e.g., 135mm, 140mm, 150mm) and thicknesses (20mm–25mm), or develop a new mold for exclusive profiles.
For large-scale developments, we offer consistent color matching across batches, ensuring a uniform appearance across the entire installation. We also supply matching accessories such as corner trims, end caps, and fasteners to complete the system.
Installation and Maintenance
Proper installation is key to maximizing the lifespan of WPC decking. We provide detailed installation guidelines, including recommended joist spacing (typically 300–400mm for hollow, 400–600mm for solid), expansion gap allowances, and fastening methods. Our technical team is available to review your substructure plans and offer advice on ventilation and drainage.
Maintenance is minimal: periodic cleaning with soap and water is sufficient to remove dirt and prevent mildew. Unlike wood, our decking does not require sealing, staining, or painting, reducing long-term upkeep costs.
Quality Assurance and Project Support
Our factory operates under ISO9001 quality management principles, and we have established a multi-link inspection system from raw material intake to final packaging. Each production batch is tested for dimensional accuracy, surface quality, and physical performance before dispatch.
We support projects from sample approval to container loading. Our export experience ensures proper packaging for sea freight, protecting boards from moisture and damage during transit. We also coordinate with logistics partners to meet your delivery schedule.
Information We Use to Configure Your Solution
To prepare an accurate quotation and technical proposal, please provide the following details:
- Project location and environmental conditions (e.g., coastal, high UV, freeze-thaw)
- Total decking area and board dimensions required
- Preferred profile type: hollow or solid
- Color and surface finish preferences
- Substructure type and joist spacing, if known
- Expected foot traffic or load requirements
- Quantity and delivery destination
With this information, we can recommend the most suitable product configuration and provide samples for your approval before mass production.
Frequently Asked Questions
What is the difference between hollow and solid WPC decking?
Hollow decking has internal chambers that make it lighter and more affordable, while solid decking is denser and stronger, offering higher load capacity and impact resistance. Hollow is ideal for residential decks, solid for commercial or high-traffic areas.
Can you produce custom colors and profiles?
Yes, we can customize colors, surface textures, and profile dimensions. For unique shapes, we can develop new molds. Minimum order quantities apply for custom tooling.
How do you ensure color consistency across batches?
We use precise pigment dosing and maintain strict process controls. For large projects, we recommend ordering a single production run to guarantee uniformity. We also retain batch samples for reference.
What is the typical lead time for a container order?
Lead time depends on quantity and customization. Standard products typically ship within 15–20 days after deposit. Custom orders may require additional time for mold development and sampling.
Do you provide installation instructions?
Yes, we supply detailed installation manuals with each order. Our technical team can also provide remote support or on-site guidance for large projects.
